Arachnids have eight legs and segmented bodies made up of two main parts - the cephalothorax and the abdomen. They can be found everywhere except the open ocean and include spiders, scorpions and mites. Arachnids breathe through book lungs or tracheal systems and have an open circulatory system. They reproduce sexually and give birth to live young or lay eggs. Common characteristics include a hard exoskeleton, venom glands, and respiratory, excretory and nervous systems adapted for their lifestyle. Arachnids are generally solitary and prefer brief mating encounters.

The reptile
Reptiles have scales that retain moisture and lay amniotic eggs adapted for land. They live in varied habitats except very cold areas as they are ectothermic. All reptiles share scaly skin, claws, lungs, and lay amniotic eggs. Adaptations like strong skeletons and claws allow movement on land while highly developed vision aids predation and predator avoidance. Ectothermy limits habitats but basking and shade-seeking regulate temperature. Lungs and partially divided hearts aid gas exchange. Reproduction is usually oviparous but some are ovoviviparous, protecting eggs inside females.
Amphibia class
a cold-blooded vertebrate animal of a class that comprises the frogs, toads, newts, and salamanders. They are distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.
Amphibians
Amphibians evolved from lobe-finned fishes around 345 million years ago. They can live both on land and in water, using various organs for respiration in different environments. There are over 2,000 living amphibian species classified into four orders: Anura (frogs and toads), Urodela (salamanders), Trachystoma (mud eels), and Apoda (caecilians). Amphibians have key adaptations like permeable skin and an aquatic larval stage that allow them to transition between aquatic and terrestrial habitats.
Presentation
Snakes have well-formed biting apparatuses coupled with toxic venoms produced by poison glands. Their fangs are long, pointed, and hollow, allowing venom to be injected. The biting mechanism involves opening the mouth through muscle contraction, rotating the maxilla bone to erect the fangs, and then closing the mouth to inject venom. Snake venoms contain complex chemical mixtures including enzymes and proteins that can be neurotoxic, causing paralysis, or haemotoxic, resulting in tissue damage and hemorrhaging. The first aid treatment for a snake bite involves remaining calm, immobilizing the bitten area, seeking medical help, and avoiding actions like cutting the wound or sucking out venom.
CLASSIFICATION OF MAMMALS
Mammals are classified into 5420 species within 152 families and 29 orders. The two subclasses are Prototheria and Theria. Prototheria contains monotremes like platypuses and echidnas that lay eggs. Theria contains marsupials in the infraclass Metatheria that give birth to immature young developing further in pouches, and placentals in Eutheria that give live birth to mature young. Marsupials include opossums and kangaroos, while placentals make up the majority of mammal species and include humans, whales, bats and more. Classification systems continue to evolve as new genetic and fossil evidence is discovered.
Arthropod classification
This document classifies arthropods into three subphyla: Trilobitomorpha, Chelicerata, and Mandibulata. Trilobites were diverse marine invertebrates that lived 500-250 million years ago. Chelicerates include spiders, scorpions, ticks, and sea spiders and have two body segments, pedipalps for holding prey, and book lungs. Mandibulatans include insects, centipedes, millipedes, and crustaceans and have mandibles for chewing and three body segments in insects.
Reptiles
Reptiles were the first terrestrial vertebrates and dominated during the Mesozoic era. There are around 7,000 reptile species worldwide today, with the most successful group being squamates (snakes and lizards). Reptiles are characterized by scaly skin, laying amniotic eggs, and various anatomical adaptations for living on land such as efficient lungs and kidneys. The four surviving orders are squamates, crocodilians, turtles, and the tuatara; turtles are notable for their protective shells.
Amphibian history notes
The document discusses the characteristics and evolution of amphibians. It notes that lobe-finned fish were ancestors of amphibians, which allowed them to move between bodies of water. There are approximately 4,000 known amphibian species classified into three orders. Amphibians are characterized by their permeable skin, three-chambered hearts, and typically having an aquatic larval stage before transforming into terrestrial adults.

Examples are given of advanced eusocial insect societies like ants, bees, and termites that live in colonies with castes and cooperative care of young.
Class Arachnida Notes
The document discusses the class Arachnida, which is characterized by having two main body parts - a cephalothorax, which is a fused head and chest region, and an abdomen. The cephalothorax has eight legs attached to it. Spiders, which are in the order Araneae, have chelicerae or fangs and pedipalps or leg-like appendages, and their abdomen terminates in spinnerets which produce silk.
Arthropods - An Introduction
Introduction to the most successful animals on Earth, the arthropods. May be used for Junior or Senior High School
Respiration in amphibians and reptiles
- Amphibians can respire through their skin, lungs, and gills. Larval amphibians use their gills and skin, while adult amphibians primarily use their lungs but can also use their skin.
- As frogs develop from tadpoles, they absorb their gills and their lungs take over respiration. More terrestrial amphibians like toads have larger lungs with more respiratory surfaces.
- Reptiles exclusively use lungs for respiration and do not go through an aquatic larval stage like amphibians. Their lungs are often divided into chambers and have alveoli to increase surface area for gas exchange.
Scorpion
Scorpions are poisonous arachnids found in tropical and subtropical regions. They are nocturnal predators that hunt insects and spiders. Scorpions have a segmented body with a cephalothorax, pre-abdomen, and post-abdomen. They have pedipalps that end in claws used to capture prey and inject venom. Scorpions breathe through book lungs and reproduce viviparously, with the young riding on the mother's back for about a week after birth.

Classification of reptiles
Reptiles are a group (Reptilia) of tetrapod animals comprising today's turtles, ... The reptiles were, from the outset of classification, grouped with the amphibians. ... between lizards, birds, and their relatives on the one hand (Sauropsida)
Birds
- Birds evolved from reptiles and Archaeopteryx possessed both reptilian and avian features. Key avian traits include feathers, hollow lightweight bones, beaks, endothermy, and amniotic eggs.
- Birds have highly specialized organ systems for flight including strong heart and respiratory systems. Their feathers provide insulation and flight abilities.
- There are many orders of birds with varied traits like waterfowl that are aquatic, owls with keen vision and hearing, and songbirds that communicate through song.
Characteristics of mammals
Mammals share 7 key characteristics: (1) making milk, (2) breathing air, (3) being endothermic, (4) having hair, (5) having specialized teeth, (6) sexual reproduction, and (7) having large brains. Placental mammals make up the majority of mammals and their embryos develop inside the mother's uterus, receiving nutrients via the placenta. Living placental mammals are divided into 11 main groups including insectivores, rodents, carnivores, hoofed mammals, primates, and cetaceans.
17. Class Chondrichthyes Notes
Class Chondrichthyes includes cartilaginous fish such as sharks, rays, and skates. They have skeletons made of cartilage and possess movable jaws and teeth. Their skin is rough and sandpaper-like, made of scales with the same composition as teeth. Sharks have been largely unchanged for over 100 million years. The largest predatory fish ever was the ancient megalodon shark, which was twice the size of a great white shark.
Classification of aves
All birds are in the Animalia Kingdom, Phylum of Chordata (with a backbone), and Class Aves (birds). At the Order level, the birds begin to diverge. For instance, the pelicans are in the Pelecaniformes Order while the nuthatches are in the Passeriformes Order.
Phylum Arthropoda
The document summarizes key characteristics of the phylum Arthropoda. Arthropods have segmented bodies, jointed exoskeletons, and appendages for feeding, sensation, defense and locomotion. They include insects, arachnids, crustaceans and trilobites. Arthropods are found in many environments and have a variety of respiratory, circulatory and digestive systems.
URINOGENITAL SYSTEM
The urinogenital system includes the urinary and reproductive systems of vertebrates. The urinary system includes kidneys and ducts, while the reproductive system includes gonads and ducts. These two systems are closely related in vertebrates. The kidneys develop from the pronephros, mesonephros and metanephros in embryos. The metanephros contains nephrons, the functional units of vertebrate kidneys. Male gonads are testes that produce sperm, while female gonads are ovaries that produce eggs. Sperm and eggs meet during reproduction and are exchanged via various genital ducts and organs between males and females.
Insect respiratory system
This document discusses the respiratory system of insects. It begins by defining respiration as the process of gas exchange between an organism and its environment. It then describes the main components of the insect respiratory system, which includes spiracles, trachea, tracheoles, and air sacs. Spiracles allow air to enter the body and are surrounded by valves and a peritreme. Trachea are elastic tubes that branch throughout the body and terminate in fine tracheoles near cells. Air sacs act as oxygen reservoirs and provide other functions. The document classifies different types of respiratory systems in insects based on the number and location of open spiracles.
The bird
This document discusses the key characteristics of birds. It notes that birds are endothermic, having feathers, wings, and a lightweight skeleton adapted for flight. Their fast metabolism allows efficient digestion to fuel flight and maintain a high body temperature of 40-44 degrees Celsius. Feathers insulate birds and flight requires adaptations like a strong breastbone and fused collarbone. A bird's beak and feet reflect its diet and habitat, with different shapes for perching, wading, or catching prey.
Reptiles class
1. Reptiles originated from primitive labyrinthodont amphibians during the Carboniferous period and underwent two major periods of adaptive radiation - in the Paleozoic and Mesozoic eras.
2. During the Mesozoic era, reptiles dominated land, sea and air, represented by 16 orders, including dinosaurs, pterosaurs, marine reptiles and the ancestors of modern crocodiles and birds.
3. Transitional fossils like Archaeopteryx provide evidence that birds evolved from reptiles with feathers and wishbones evolving among traits shared with modern avians.
Respiratory system of pila
Pila is an amphibian that can perform both branchial and pulmonary respiration. When in water, it breathes through gills called ctenidia located in the branchial chamber. On land, it breathes through a pulmonary sac located in the pulmonary chamber. The pulmonary sac allows for gas exchange between air and blood. Pila can also respire underwater using a respiratory tube formed by its nuchal lobe to bring air into the pulmonary sac. Its osphradium organ helps detect chemicals in the water.
Phylum Annelida
This document summarizes key characteristics of the phylum Annelida. It describes the three classes - Polychaeta, Aelosomata, and Clitellata (with subclasses). It then discusses the basic body plan, skeletal system, circulatory system, digestive/excretory system, reproductive system, nervous system, and some examples of specific annelid worms like the sea mouse, giant feather duster, leeches, giant Australian earthworm, colonial polyps, and king ragworm.
Predatory and Spider mite interaction
The document discusses the morphological and behavioral adaptations of predatory mites that allow them to prey on spider mites. It describes the different life types of spider mites, including little web, complicated web, and web nest types. It also characterizes the life styles of various predatory mite species as specialists that can invade spider mite webs or generalists that forage outside of webs. Specialist predators like Phytoseiulus persimilis and Galendromus helveolus have adaptations like thread-cutting abilities that facilitate predation within spider mite webs. Understanding these life styles and adaptations can help select compatible predator-prey combinations for biological control of spider mites.
All Mites
The document summarizes different types of mites including itch mites, house dust mites, and scrub typhus mites. Itch mites cause scabies in humans through burrowing under the skin. House dust mites are found worldwide in dust and are a common cause of allergies. Scrub typhus is transmitted by the larvae of trombiculid mites and causes a disease called scrub typhus in parts of Asia and Australia.

Arachnida ppt
Arachne, a skilled weaver, challenged the goddess Athene to a weaving contest and lost. In her rage, Athene tore Arachne's tapestry and transformed her into the first spider. Spiders are part of the arachnid class and secrete venomous poison from their jaws to paralyze prey, though few spider bites are actually poisonous to humans. Spider venoms produce symptoms in poisonings and homeopathic provings that are similar to the conditions they can treat, such as swelling, tissue breakdown, lymph node swelling, and nervous symptoms. Each substance, including spider venoms, has a unique pathogenic and therapeutic effect.

two spotted mite
The document discusses the two spotted spider mite, Tetranychus urticae. It describes the mite's morphology, life cycle, distribution, host plants, and economic importance. The two spotted spider mite can damage a wide range of plants by feeding on their leaves and flowers. Management strategies discussed include biological control using predator mites and insects, as well as chemical control using miticides.
Biological control of phytophagous mite
Phytophagous mites are plant-feeding pests that damage crops. Predatory mites in the family Phytoseiidae provide effective biological control by voraciously feeding on phytophagous mites like the two-spotted spider mite. Releasing predatory mites like Phytoseiulus persimilis at early signs of an infestation can suppress pest mite populations without the need for pesticides. Proper timing and methods are required to establish predatory mites and allow them to control phytophagous mites in an economical and sustainable manner without the pest mites developing resistance.

Chapter 26 notes Arthropods.ppt
Arthropods are a phylum of jointed-limbed invertebrates that include insects, arachnids, crustaceans and others. They have segmented bodies, exoskeletons, and jointed appendages. Arthropods are highly diverse, with six main classes. Insects are the largest class and undergo complete or incomplete metamorphosis from egg to adult. Spiders and scorpions are arachnids with eight legs and silk-spinning abilities. Crustaceans include crabs, shrimp and barnacles, most living in water. Centipedes and millipedes differ in having an odd/even number of legs per segment. Horseshoe crabs are ancient marine ar

Chapter 26 notes Arthropods.ppt
Arthropods are invertebrates with segmented bodies and jointed appendages that include insects, arachnids, crustaceans, and others. They have an exoskeleton, a segmented body, and bilateral symmetry. Arthropods have well-developed senses including compound eyes, taste and smell receptors. They undergo molting to grow, have open circulatory systems, and many reproduce sexually with internal or external fertilization. The largest class is Insecta, which undergo complete or incomplete metamorphosis from egg to adult.
Spider Taxonomy
Spiders have a two-part body consisting of a cephalothorax and abdomen connected by a pedicel. The cephalothorax bears eight eyes and six pairs of appendages including chelicerae with poison glands. The abdomen contains book lungs and spinnerets used to spin silk. Spiders are predators that use silk and venom to capture prey, and most species are nocturnal.

Here are the key structures to locate in the thoracic cavity:
1. Locate the heart. The heart is located in the thoracic cavity, surrounded by the pericardial sac. It is a muscular organ that pumps blood throughout the body via arteries and veins.
2. Locate the lungs. The lungs occupy most of the posterior thoracic cavity. They are soft, pinkish-gray organs responsible for gas exchange between inhaled air and blood.
3. Locate the trachea. As reviewed earlier, the trachea is a cartilaginous tube that carries air from the mouth and nose into the lungs. It branches into the two mainstem bronchi that enter each lung.

It covers the main body parts and systems of insects, the four main types of insect life cycles including complete and incomplete metamorphosis, and how insects are classified into taxonomic groups from kingdom to species. It also notes that while some insects can be harmful, most play important ecological roles such as pollination, food production, and decomposition.
Animalia
The document discusses the Search for Extraterrestrial Intelligence (SETI) project which searches outer space for signs of life. It notes that the US spends millions of dollars annually on SETI to search for aliens. It then asks if readers believe in the possibility of aliens and asserts that there may be aliens on other planets in the universe given the vast number of solar systems.
Phylum Annelida Dating Service
The document introduces the phylum Annelida, or segmented worms. It notes that annelids can live in marine sediments, soil, or as parasites inside other organisms. They have a segmented body that allows separation of organ systems and bilateral symmetry. Annelids have a closed circulatory system, coelom, and separate mouth and anus.

Arachnids
- 1. Arachnids
- 2. We, the Arachnida class, are part of the Arthropoda phylum. Are the first things you look at when you see your potential mate his/her legs? Well, we have EIGHT LEGS !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Like the feel of silk? Spiders will gladly wrap you in some! Want protection? Many of us fight with venom! Last but not least, there would be no Spider-Man without us!
- 4. Favorite Activities This is what happens when you give too much free time to spiders. => Nobody tends to get a picture of a scorpion attacking something because they attack so fast (duh), so here’s one in attack mode! BLOOOOD!
