Classification o animals
Scientists divide the Animal Kingdom into two main groups: vertebrates, which have backbones, and invertebrates, which do not. Vertebrates are then divided into mammals, birds, reptiles, amphibians, and fish. Mammals are warm-blooded and furry or hairy, feed their young milk, and give live birth. Birds are warm-blooded and covered in feathers, lay eggs which hatch into chicks. Reptiles are cold-blooded and covered in scales, lay eggs. Amphibians can live on land and water, are moist and smooth, lay eggs. Fish live in water, are cold-blooded and covered in scales, breathe
Invertebrates-INSECTS
Insects have distinct body characteristics including a head, antennae, legs, abdomen, and thorax. They eat a variety of foods like plants, nectar, seeds, and grass. Insects live in nearly every habitat on Earth from deserts to mountains to streams, with most living on land. Insects reproduce by laying eggs and the babies, called larvae, look very different than the adults. Their key characteristics are being cold-blooded, having six legs, three main body parts, an exoskeleton, and many have four wings.
Birds
Birds are vertebrates that have feathers and lay eggs. They have two legs and while most birds can fly, some like ostriches and penguins cannot. Birds come in many varieties such as ducks, owls, flamingos, eagles, parrots and vultures.
Reptiles, Amphibians and fish ppt
This document discusses the characteristics of reptiles, amphibians, and fish. It notes that most reptiles lay eggs on land and have scales, while amphibians lay eggs in water and undergo metamorphosis. It also explains that fish breathe with gills and many are oviparous, though some keep their eggs in their mouths until hatching and sharks give live birth.
Mammals
Mammals are a class of warm-blooded vertebrates that have hair or fur and produce milk to feed their young. The document discusses the key characteristics of mammals and divides them into subclasses and orders. It provides examples and details for monotremes, marsupials, and placentals. The largest orders described are rodents, bats, cetaceans, carnivorans, artiodactyls, and primates.
Reptiles ppt
Reptiles are cold-blooded animals that can survive on land and in water. There are four main groups of reptiles: crocodiles, lizards, turtles, and snakes. Crocodiles are found in tropical environments and can stay underwater for over an hour. Lizards come in many varieties and shed their skin as they grow. Turtles have a hard shell and can retract their head inside. Snakes shed their skin several times per year as they grow and are carnivorous.
BIRDS
Birds are vertebrate animals with feathers and beaks that can fly, stand, walk or run. They live on every continent and eat a variety of foods like fruit, plants, fish, seeds and insects. Birds communicate using songs, calls and visual signals like wing flapping. Many birds lay eggs in nests and are cared for by their parents.

The Birds
Birds are warm-blooded vertebrates that have feathers, beaks, and lay eggs. They use their feathers for protection, breathing, and movement. Birds such as song thrushes and owls have unique characteristics - song thrushes build nests and eat worms while listening for prey underground, and owls hunt at night using sharp claws and silent flight to catch mice and rats.
Reptiles
This document discusses the characteristics of reptiles, noting that snakes, crocodiles, turtles, and lizards are reptiles. Reptiles are vertebrate animals with skeletons, backbones, and scales; they are born from eggs and can have four legs, no legs, live in water or on land, and eat plants or meat.
ANIMAL CHARACTERISTICS
The document defines the characteristics of mammals, birds, reptiles, amphibians, fish, and insects. Mammals have hair, give birth to live young, and feed their babies milk. Birds lay eggs, have feathers and wings, and can fly. Reptiles lay eggs, have scales, and may have no legs or four legs. Amphibians have wet skin and live both on land and in water. Fish lay eggs, live only in water, have scales, fins, and gills. Insects have six legs, a head, thorax, abdomen, and antennae and are invertebrates that lay eggs.
Birds
Birds are vertebrates that lay eggs and have feathers, wings, and a beak. They breathe with lungs and have lightweight skeletons that allow most birds to fly, though some like ostriches cannot. Common types of birds include sparrows, pigeons, ducks, chickens, flamingos, owls, and parrots.
Class Aves
Birds are characterized by feathers, wings, a beak or bill, laying eggs, a lightweight skeleton, and molting. Feathers are made of keratin and have several functions, including flight, insulation, incubation, courtship, and waterproofing. There are two main types of feathers - pennaceous feathers which form the wings and tails and provide lift, and plumulaceous feathers which are wispy and insulative. Birds have strong flight muscles and either monogamous or polygamous reproductive behaviors, where they build nests and care for altricial or precocial offspring after laying clutches of eggs.
Life cycles of some animals
The document describes the life cycles of several animals including eagles, butterflies, frogs, and mammals. Eagles lay eggs which hatch into eaglets. Butterflies go through stages of an egg, larva/caterpillar, pupa, and finally an adult butterfly. Frogs undergo metamorphosis from eggs to tadpoles to adult frogs. Young mammals like bobcats develop from eggs inside their mother's body and are born as kittens, growing into adults.
Animals classification
This document classifies animals according to their structure, diet, and reproduction. It divides animals into invertebrates without backbones and vertebrates with backbones. Invertebrates include arthropods, worms, mollusks, sponges, and echinoderms. Vertebrates include mammals, birds, fish, reptiles, and amphibians. Mammals are viviparous and nourish their young with milk. Birds lay eggs but are otherwise diverse. Fish primarily reproduce through laying eggs while reptiles can be either viviparous or oviparous. Amphibians undergo metamorphosis from aquatic young to terrestrial adults.
Agnatha
There are only a few vertebrates that have no jaws, such as lampreys and hagfish. Jaws evolved from gill arches in fish and provided benefits like being able to hold food so it couldn't escape from the stomach. Paired fins also evolved around the same time, and it would have been difficult to swim without front fins. Both lampreys and hagfish are jawless fish, with lampreys having an eel-like body structure and hagfish having eyes beneath their skin and no vertebrae.
Butterfly
The document outlines the 4 stages in the life cycle of a butterfly:
1) Egg stage - Eggs are laid on leaves and take 1-3 weeks to develop into caterpillars.
2) Caterpillar or larva stage - The caterpillar emerges from the egg and eats voraciously, shedding its skin several times as it grows.
3) Pupa stage - The caterpillar forms a cocoon and undergoes metamorphosis within, emerging after weeks or months as a butterfly.
4) Adult stage - The butterfly emerges from its cocoon with wings and a familiar form, living on average only a few weeks before the cycle repeats.
Mammals presentation
This document discusses different types of mammals. It describes three main groups of mammals: monotremes, marsupials, and placental mammals. Key details include monotremes laying eggs and nursing their young, marsupials giving birth to underdeveloped young that attach to the mother's pouch, and placental mammals being born at an advanced stage through a placenta. The document also outlines the fastest, slowest, largest, and smallest mammals as well as other interesting mammal facts.
Mammals
Mammals are characterized by warm-bloodedness, hair or fur, highly developed brains, muscular diaphragms, mammary glands, and parental care. They have four-chambered hearts, skulls with teeth and jaws, and two sets of teeth. Mammals have four limbs adapted for locomotion like walking, running, swimming, flying or burrowing. They maintain a constant body temperature through homeothermy. Their skin has hair and glands. Mammals are classified into monotremes, marsupials, and placental mammals.

This document discusses the life cycles of different living things, specifically comparing complete and incomplete metamorphosis. It provides examples of the butterfly and frog life cycles to illustrate complete metamorphosis, where the organism changes completely in shape and form between stages. The chicken life cycle is given as an example of incomplete metamorphosis, where the changes are less drastic and the young still resemble the adult. Key stages of the butterfly and frog life cycles like egg, larva, pupa, and adult are defined.
Animals and their young
The document discusses animals and their young. It defines what animals are, noting they are living things that can move in different ways. It also explains that animals come in many types and have babies with different names, like tadpoles for frogs. The document then matches young animals, such as kittens for cats, calves for cows, and cubs for lions, with their mothers.
Life Cycle Of The Butterfly
This document summarizes the life cycle of a butterfly through four stages:
1) Egg - The first stage where butterflies lay eggs on leaves.
2) Larva (caterpillar) - The second stage where the caterpillar hatches and eats leaves, molting several times as it grows.
3) Pupa (chrysalis) - The third stage where the caterpillar undergoes metamorphosis inside the chrysalis.
4) Adult - The fourth and final stage where the butterfly emerges with wings and mates, continuing the cycle.
Birds ppt
Birds have several key features that help them survive and thrive. They have wings that allow most birds to fly, lightweight hollow bones, and claws and feet adapted for their environments and diets. Birds also have beaks suited to their food sources - some have crushing beaks, others curved or probing beaks. Their bodies are streamlined for flight and many have specialized leg and foot structures for swimming, wading, or perching.
Mammals, birds, fish and amphibians (ScienceandEnglish.com)
Mammals are vertebrates that have fur or hair, breathe with lungs, give live birth, and drink milk from their mothers as babies. They come in a wide range of sizes from the smallest mice to the largest whales and elephants. Mammals can walk on four legs or have flippers to swim and are herbivores, carnivores, or omnivores depending on their teeth.
Types of animals
The document describes different types of animals including mammals, birds, fish, reptiles, and amphibians. It defines their key characteristics such as having fur or feathers, breathing methods, birthing young, and whether they lay eggs. Examples are provided of animals that would be classified as mammals, birds, fish, and amphibians based on these distinguishing traits. The purpose is to teach how to classify animals based on their physical features, means of reproduction, and locomotion.
MY FAVOURITE ANIMAL
The document discusses the narrator's three favorite animals: dolphins, leopards, and cats. Dolphins are gray whales that live in oceans, have long tails and noses, and swim and hunt fish well. Leopards are yellow big cats with black spots found in Africa that have sharp teeth and hunt prey in tall grass. Cats are domestic pets with claws and eyes that eat meat, fish, and milk, and can run and jump. The narrator's pet cat Barsik is gray and they teach it tricks and consider it a good friend.
The spiders
Spiders can live in almost any habitat except oceans, high mountains, and polar regions. They have two body segments - the cephalothorax contains the eyes, mouth, brain, and poison glands, while the abdomen contains the silk-producing spinnerets. Spiders have 8 eyes, pedipalps near the fangs, 48 knees, and an exoskeleton that young spiders molt. They are predators that eat insects and other spiders, though large spiders may occasionally catch small vertebrates, birds, or bats. Spiders reproduce through eggs and have a lifecycle where the young spiders grow and molt until adulthood.
The Life cycle of frog
Frogs go through distinct stages of development from egg to adult. They begin as frog spawn, laying eggs in water. These hatch into tadpoles with tails and live in water. Over 5 weeks, tadpoles grow hind legs and lungs as their tails shrink. They become froglets and then young frogs, shedding their tails and developing fully on land as adult frogs that live mostly on land and eat insects.
Reptiles
Reptiles are vertebrates that lay eggs and have scales covering their bodies. They are cold-blooded and breathe with lungs. While some reptiles have four legs, others have no legs or shells. Common reptiles include crocodiles, alligators, turtles, tortoises, snakes, lizards, chameleons and iguanas.

Amphibians
Amphibians live part of their lives in water and part on land, near water or damp places. They lay eggs in water and baby amphibians live and grow in water, changing through metamorphosis into adults. Examples of amphibians include frogs, salamanders, newts and toads.
Parantal care in fishes
Parental care in fishes involves various behaviors to protect eggs and offspring. Many fish build elaborate nests, such as sunfish creating shallow basin nests. Others guard eggs in their mouths or coil around them. Parental care increases survival chances for offspring and helps continue species. Behaviors seen include nest building, guarding eggs, and caring for hatchlings. Parental care is an important evolutionary development for fish reproduction.
Comparative Anatomy - Skeletal System
The skeletal system is the most important organ system for studying vertebrate morphology. It provides shape, support, and protection to the body. The skeletal system consists of two main parts - the axial skeleton which includes the skull and vertebral column, and the appendicular skeleton. The axial skeleton gives the body its basic form and protects the spinal cord and vital organs. It develops from cartilage that later ossifies into bone. The skull is made up of the neurocranium, dermatocranium, and splanchnocranium. Vertebrae come in different shapes depending on the number and fusion of centra. Ribs attach to vertebrae and form a protective rib cage in most vertebrates

Reptiles lay eggs and have scales, while amphibians can live on land and water and have moist skin. Fish live exclusively in water, breathe through gills, and use fins to move. All five groups have an internal skeleton and spinal column.
Animals
In this PPT we have given animal classification. vertebrates and invertebrates. We have also given definition of different types of animals and supporting pictures. Standard 1 children can see this PPT for their NSO preparation.
Vertebrates
This document discusses the key characteristics of vertebrates and their five major classes: Pisces, Amphibia, Reptilia, Aves, and Mammalia. It defines vertebrates as animals that have a backbone or spinal column. All vertebrates possess features like a notochord, dorsal nerve cord, and are bilaterally symmetrical. Each class is then defined, such as fish being exclusively aquatic and having scales, reptiles laying eggs on land rather than water, birds being warm-blooded and having feathers, and mammals having hair and mammary glands. Examples are provided for each class.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Amphibians
- 1. Amphibians
- 2. Amphibians are vertebrates Amphibians have a skeleton inside, so they are vertebrates
- 3. Amphibians are oviparous Amphibians lay eggs. They are born from these eggs
- 4. Metamorphosis Amphibians change their body when they are adults. They are born in water, like fish. They can swim and breathe with gills When they are adults, they grow four legs and lungs. They have to breathe air.
- 6. Bare, moist skin Amphibians don’t have hair, scales or feathers covering their body. They have a bare and moist skin. They use the skin to breathe as well.
- 7. Four legs when adults Amphibians are born with no legs, but they grow four legs when they’re adults.
- 8. Some amphibians are… Frog Toad Salamander Newt
- 9. Summing up! Amphibians are vertebrates They are oviparous They have a metamorphosis: their body changes from babies (no legs, live in water) to adults (four legs, breathe air)
