chondrichthyes and osteichthyes are the two classes of gnathostomata where fishes also lies
Fish float in water due to their buoyancy. Their bodies are less dense than the water they displace, so they are able to stay afloat. Additionally, fish have swim bladders, air-filled organs that help them control their buoyancy and maintain their position in the water column.
Oviparous fishes lay many eggs to increase the chances of offspring survival, as only a few may actually develop into adults. Viviparous fishes invest more energy in developing fewer offspring to ensure their survival by providing them with nutrients and protection during gestation. This leads to a higher likelihood of offspring reaching maturity compared to oviparous fishes.
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.
Fish need to descend or rise to different water levels to regulate their buoyancy, avoid predators, find food, or locate suitable spawning or breeding grounds. By moving to different depths, fish can adjust their position in the water column to meet their specific biological needs.
so that we will know where they come from
I need time to familiarize myself with the new software before I can use it efficiently.
