Form 5: Chapter 2 – Locomotion and Support 2.1 Support and Locomotion in Humans and Animals This document summarizes how fish are able to swim and move efficiently in water. It explains that a fish's body is streamlined and covered in overlapping scales to reduce resistance in water. The fish's vertebral column moves from side to side as myotomes, or W-shaped muscle blocks, contract and relax on either side of the body in an alternating wave. This sweeping motion pushes water backwards and propels the fish forward. Fins help counter unwanted pitching, yawing, and rolling movements and provide thrust and directional control. A swim bladder containing gas helps the fish control its buoyancy to

A SURVEY ON UNDULATORY MOTION BASED ROBOTIC FISH DESIGN
Robotic fish design (Biomimetic) is an upcoming research area in which undulation motion has its own set
of parameters to decide its efficiency. To analyse its swimming efficiency several existing robotic models
using undulation motion have been thoroughly studied and few critical parameters such as fin size, shape,
flexibility of material, fin flapping rate etc., have been identified. After simulating the above critical
parameters using a MATLAB based CFD tool, mainly to design prototypes for research purpose which
concentrates on optimizing its swimming efficiency. Several combinations of critical parameters are
discussed for robotic fish prototype design by identifying critical parameters and maximizing the swimming
efficiency of robotic fish based on the above properties. The fin models have been tested using Matlab
based CFD tool through simulation and the swimming speed, direction have also been tested for various
models. An improved benchmark for designing robotic fish model is proposed in order to simplify selection
of components, architecture, and cost involve.
Animal movement
This document summarizes different types of animal movement in water and air. It discusses how fish propel themselves using body-caudal movement powered by undulating muscles along their body and tail fin. It also describes how sharks and other fish maintain buoyancy using dynamic lift from pectoral fins or a swim bladder. Aquatic invertebrates like jellyfish and starfish move via hydrostatic skeletons and contractions of their fluid-filled bodies. Water mammals like dolphins and whales use powerful tail strokes, while sea otters rely on large lungs for buoyancy. Flight in birds is enabled by specialized feathers forming airfoils and hollow bones reducing weight; they can both flap wings and glide or soar using therm
Fish swim
Fish swim using undulations of their body and fins. They have a network of muscles that contract and relax to create waves that travel down the body and propel the fish forward. Fins provide control, thrust, lift, and drag. Forces acting on the fish include thrust from parts of the body pushing against water and lift and drag forces. Fish also generate lift using their swim bladder by inflating or deflating it with oxygen to control buoyancy. Forces resisting the fish's movement include frictional, pressure, and form drag.
Aquatic adaptations
Introduction:
Adaptation to environment is one of the basic characteristics of the living organisms. Living organisms are plastic and posses the inherent properties to respond to a particular environment.
It is a facet of evolution and involve structural diversities amongst living organisms that are heritable. Organisms exhibit numerous structural and functional adaptations that help them to survive as species and to overcome the tremendous competition in nature.
All classes of vertebrates have their representatives leading to partial or total aquatic life.
Water is a homogenous medium for animals.
As a medium, it is heavy in concentration than air.
Stable gaseous and osmotic concentration in a specific region.
Temperature fluctuation is minimum for a particular region.
Water bodies generally have very rich food resources.
Characters of an Aquatic Animal:
An aquatic animal should have the ability to swim to overcome the resistance of the surrounding medium.
Therefore, it should have a streamlined body with an organ or ability to float.
The animal should also have to overcome the problem of osmoregulation.
There are two types of animals living in the present day water, which have undergone aquatic adaptation.
According to their origin, they are primary and secondary aquatic animals.
Adaptations to water habitat are of two types:
Primary aquatic adaptations which includes primitive gill-breathing vertebrates (fishes); Those animals, whose ancestors and themselves are living in the water from the very beginning of their evolution, are called primary aquatic animals. In other words, primary aquatic animals never had a terrestrial ancestry. They exhibit perfect aquatic adaptations. All fishes are primary aquatic animals.
Secondary aquatic adaptations which are acquired as in reptiles, birds and mammals. Those animals whose ancestors were lung breathing land animals, migrated to the water for some reason and ultimately got adapted to live in aquatic habitat, are called secondary aquatic animals. Some of them live partially while others live totally in the water. All aquatic reptiles, aves and mammals are representatives of secondary aquatic animals. Amphibians are in a transitional form between primary and secondary aquatic life.
Sensory adaptations like, electroreception for electrolocation and electro communication, olfaction (vomeronasal system), balance (spatial orientation, movement perception), vision (cornea curvature, retinal topography), and hearing (acoustics, ear anatomy) under the underwater sound reception mechanisms in various aquatic amniotes are well developed.
Fins and locomotion in fishes by Iram Bee M.Sc. II Year.pptx
Fins are key anatomical features of fish that aid in locomotion and other functions. The document discusses the various types of fins found in fish and their purposes. It outlines that fins help with swimming through undulation and thrust generation. Pectoral fins can aid flying fish in gliding and various fins are modified for other functions like reproduction and defense. Fins work with different swimming styles like anguilliform to propel fish through the water.

Swimming pe
Swimming is a sport that involves moving through water using the entire body. There are various competitive swimming strokes including breaststroke, butterfly, backstroke, freestyle, and individual medley. Swimming has been practiced since ancient times and has been an Olympic sport since 1896. It is considered a full-body exercise that provides cardiovascular and muscular benefits while being low impact, making it a suitable exercise for people of all ages and physical abilities. Common equipment used in swimming includes swimsuits, goggles, caps, kickboards, paddles, and pull buoys.
Presentation on aquatic mammals
The document discusses the aquatic adaptation of mammals. It acknowledges those who helped with the seminar topic. The contents include introduction, adaptation of aquatic mammals, modification and loss of original structures, development of new structures, types of aquatic mammals, and conclusion. It describes various anatomical modifications that aquatic mammals undergo, such as streamlined bodies, flippers, valvular nostrils, large lungs, blubber, and tail flukes to adapt to aquatic living.
Adaption of animals
The document discusses three types of animal adaptations: aquatic, volant (flight-related), and desert adaptations. Aquatic adaptations in primary aquatic animals include streamlined bodies, swimming organs like fins, respiration through gills or diffusion, and buoyancy organs like swim bladders. Secondary aquatic animals also have streamlined bodies and enlarged sizes. Volant adaptations include the development of wings, feathers, lightweight skeletons, and flight muscles in birds. Desert adaptations help animals obtain and conserve moisture, like deep roots in plants or reduced sweat glands in mammals, and protect from heat/sun like thick skins.
2[1].1 (c) FORM 5
Earthworms use hydrostatic skeleton and antagonistic muscles to move forward by extending segments through fluid compression. Grasshoppers use strong hind legs and wing contractions to jump and fly. Fish rely on tail lashing and fins for stability and thrust in water. Birds evolved light bones and wings for lift via flapping, overcoming air resistance.
Aquatic mammals and their adaptation, General Feathers of Aquatic mammals
Aquatic mammals have adapted to live fully or partially in water. Some mammals, like whales and dolphins, live their entire lives in water. Others, like seals and otters, spend most of their time in water but need to return to land for activities like mating. Adaptations for aquatic life include streamlined bodies, webbed limbs or flippers, large lungs and nostrils placed high on the head. Examples of fully aquatic mammals are whales, dolphins and manatees. Semi-aquatic mammals include seals, otters and hippopotamuses.
ANATOMY OF FISH
The document provides information about the external and internal anatomy of fish, using a largemouth bass as an example:
- Externally, it describes fins, scales, lateral line, eyes, mouth, gill covers, and vent. Internally, it outlines the spine, spinal cord, brain, swim bladder, gills, kidneys, stomach, intestines, liver, heart, gonads, muscles.
- It provides details on measuring fish length and girth, and formulas for estimating weight from length and girth measurements.
- The closing paragraph notes that many fish swim by contracting muscle blocks from head to tail to flex the body side to side or up and down.
U nit 6 vertebrates (1)
This document provides an overview of vertebrates, including their key characteristics and how they are classified. It discusses the main groups of vertebrates - fish, amphibians, reptiles, birds and mammals. For each group, it describes physical features, temperature regulation, reproduction methods, and examples of common types. The largest sections are devoted to fish, amphibians, and reptiles, explaining their distinguishing attributes and subgroups in detail.
Adaptations For Movement (30 Jun)
The document discusses structural adaptations that help animals move efficiently. It explains that streamlined bodies help aquatic animals like fish move fast through water to catch prey or escape predators. Fish also have modified limbs and swim bladders to aid movement and buoyancy. The document then discusses adaptations for flight, noting that flying animals are generally lightweight with large, wing surfaces, streamlined shapes, and strong flight muscles. Birds in particular have feathers, hollow bones, and streamlined bodies to reduce air resistance and fly efficiently.
Fish anatomy
This document provides information about fish anatomy and aging using otoliths. It describes the external anatomy of fish such as fins, scales, lateral line and internal anatomy including organs like gills, kidneys and gonads. It also explains how otoliths, structures located behind the brain, are used to determine a fish's age by counting growth rings similar to tree rings. Validating the age estimates involves techniques like tagging and recapturing fish that have been injected with chemicals that appear as bands in the otoliths.

Validating the age estimates involves techniques like tagging and recapturing fish or rearing them in laboratories to compare known ages to otolith ring counts.
Support and movement[1]
1. All living things need a support system consisting of a skeleton and muscles to provide structure, movement, and survival.
2. There are three basic types of support systems - exoskeletons which are outside the body like insects, endoskeletons inside the body like humans, and hydrostatic skeletons using fluid pressure like worms.
3. The human skeletal system includes 206 bones that make up the skull, spine, ribs, and limbs to support weight, maintain shape, protect organs, and allow movement.
Aquatic adaptations in mammals by Brijesh Singh M.Sc. II year.pptx
This document discusses the aquatic adaptations of mammals. It begins by classifying aquatic mammals as either completely aquatic or semi-aquatic. It then examines the body modifications that help mammals live in water environments, including streamlined bodies, blubber for insulation, flippers for locomotion, lung and skeletal adaptations for swimming, and sensory modifications. Reproductive adaptations are also covered, such as long gestation periods so young are large enough for aquatic life. Overall, the document outlines the major physical adaptations mammals have evolved to live either fully or partially in aquatic environments.
17.2 Fish
Fishes have gills that extract oxygen from water. Water passes over the gills as fish swim, allowing oxygen to diffuse into blood vessels and carbon dioxide to diffuse out. There are three main classes of fish: jawless fish like lampreys and hagfish that lack jaws; cartilaginous fish like sharks that have skeletons made of cartilage; and bony fish, which is the largest class and have skeletons made of bone. Bony fish use a swim bladder to control their buoyancy and have scales and fins adapted for swimming.
Animal Support System
This document discusses different types of skeletons and locomotion in animals. It describes three main types of skeletons: hydrostatic, exoskeleton, and endoskeleton. Hydrostatic skeletons use fluid pressure, while exoskeletons are external shells and endoskeletons are internal structures like bones. It also outlines different modes of locomotion including swimming, movement on land through structures like joints and muscles, and flying through wing adaptations. The document concludes with assigning worksheets on topics like the human skeleton, fill in the blank questions, and crossword puzzles.
LSU MNS gulf coast sea life - fish
This document discusses fish anatomy and morphology. It describes the different types of fins found on fish, including dorsal, pectoral, pelvic, anal, and caudal fins, and explains their functions in movement and stabilization. It also outlines various fish body shapes such as fusiform, sagitiform, and anguilliform, and how these shapes aid in swimming, hiding, and maneuverability. The document provides instructions for the Japanese art of fish printing called gyotaku and an activity where students can build their own fictional "frankenfish" by combining different fish parts.
Taxonomy Of Fishes.pptx
The document discusses different ways that fish can be classified and organized taxonomically. It outlines eight key methods of fish taxonomy: 1) by scientific naming conventions, 2) physical traits measured, 3) evolutionary lineage, 4) presence of jaws or not, 5) bone structure, 6) habitat salinity tolerance, 7) position in the water, 8) migratory behavior, and 9) feeding behavior. The taxonomy of fish involves categorizing them into groups based on observable shared characteristics.
Aquatic adaptations of mammals
Aquatic mammals have undergone several anatomical adaptations for living in aquatic ecosystems. They include streamlined bodies, fins or flippers for propulsion, insulating blubber, and circulatory systems that optimize oxygen retention and delivery. Sensory adaptations allow them to navigate, hunt, and communicate underwater using echolocation. Over time, mammals independently colonized aquatic habitats through evolutionary changes like the development of tail flukes, dorsal fins, baleen plates, and other structures suited for an aquatic lifestyle.
