Its an adaptation created over time in order to help them maneuver through their environment. Evolution to be frank.
so that they can move smoothly
streamlined body. vertebrates. possess fins and gills.
the shape which is narrow in the beginning and broad in the middle is called a streamline shape. fishes have streamlined shape which makes their movement in water easier and helps to reduce water resistance.octopuses do not have a streamlined body but while moving it makes a streamlined body .boats ,fishes,airoeplanes etc have streamlineshape.
A tuna and other fishes have a thunniform body plan which is streamlined to minimize drag within the water.
Yes, mudskippers have a streamlined body shape that helps them move efficiently through the mud and water. Their flattened bodies and strong pectoral fins allow them to navigate their unique habitat of intertidal zones.
Yes it does it has a streamlined body
Fish have several adaptions to help them survive in the water. Firstly, they need gills to breathe, secondly, fins and a tail to help them swim and finally it is important for them to have a streamlined body.
Streamlined often means aerodynamic.
It reduces friction
fish need to be more streamlined than land mammals because they need to be able to stream quickly through water. They need to be able to do this for many reasons such as to either catch their prey (if they are large carniverous fish) or escape from their predator.
Sharks, Tuna, Mackerels, and Marlins are all examples of Streamlined body shape fishes.
They are streamlined and & they have light yet strong skeletons. The inside of a bird's bone is almost hollow. Internal crisscrossing structures strengthen the bones without making them as heavy as mammal bones are. Because flying requires a rigid body, a bird's tail vertebrae are joined together by to provide the needed rigidity, strength, and stability.
