What is the shape of the fish?
Bony fishes show great variety in body shape, but the “typical” fish body shape is roughly cylindrical and tapering at both ends. This characteristic fusiform shape is quite energy efficient for swimming.
What is fish morphology?
Fish anatomy is the study of the form or morphology of fishes. The main external features of the fish, the fins, are composed of either bony or soft spines called rays which, with the exception of the caudal fins, have no direct connection with the spine.
What is a fusiform body shape?
Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel.
What are the classification of fish based on morphology?
Fish are also classified as per their shape. There are two shapes of fish—round and flat. As the name suggests, flat fish are flat in appearance while round fish are well rounded and plump. There are many ways in which one can differentiate between flat and round fish (Table 13.2).
Why do fish this shape?
(i) The streamlined body shape (boat shape) allows the fish to move easily in water.
What are the adaptations of a fish?
Adaptations for Water
- Fish have gills that allow them to “breathe” oxygen in water.
- Fish have a stream-lined body.
- Most fish have several fins for swimming.
- Fish have a system of muscles for movement.
- Most fish have a swim bladder.
Why are the fish fusiform?
The generally fusiform shape of groupers and sea basses helps them attain speed, but their shape requires a broad, powerful tail to propel them through the water quickly.
What animals are streamlined?
Many animals that move through water are streamlined, including different kinds of fish, whales, stingrays, eels, and more. Marine animals are not the only ones with streamlined bodies, weasels are one example of a land dwelling animal with a streamlined body. Most types of birds will also have streamlined bodies.
Can a person be exasperating?

Why do fish have this shape 5 points?
Fish comes in various colors, shapes, and patterns. Fish’s side to side swimming motion is powered by myotome– a group of muscles served by a spinal nerve root. Initially, each future developing myotome segment is cuboidal in shape. However, over five hours, it deforms into a pointed ‘V’ shape.
What is streamlining give example?
Streamlined flow is observed when fluid is moving with slow velocities. Water flowing slowly in a pipe and motion of spermatozoa are examples of streamline flow. Motion of water flowing in a river and motion of blood in arteries are examples of turbulent flow.
What does streamlining mean?
transitive verb. 1 : to design or construct with a streamline. 2 : to bring up to date : modernize. 3a : to put in order : organize. b : to make simpler or more efficient a system that streamlines the process.
Why do fish differ in body shape?
Fish Body Shape and Movement Like all animals, the fish’s body is a result of specialization in its environment. Water is about 800 times thicker than air and an aquatic life has its own difficulties, such as buoyancy, drag and the amount of effort needed to move through such a dense medium.
Why Fish has a streamlined body?
Examples: Fishes have streamlined body so that they have less resistance when swimming in water. Birds have a streamlined body to make their flight easier through air. Snakes have streamlined body to help them move forward.
What is the importance of fins in fish?
Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling.
Why are fish streamlined?
Fish are streamlined because the streamlined shape helps them move through the water with the least amount of resistance.
What is streamlining in science class 8?
Answer: Streamlining is a design that offers the least resistance to the flow of a fluid, especially air or water. Friction is minimum for a streamlined shape, which is rounded in the front and narrow at the back. It is useful as: Ship also have streamlined shapes to reduce friction with water.
