1.The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage (cartilaginous fish) or bone (bony fish).
2.The turtle shell has a top (carapace) and a bottom (plastron). The carapace and plastron are bony structures that usually join one another along each side of the body, creating a rigid skeletal box. This box, composed of bone and cartilage, is retained throughout the turtle's life.
3.Dolphins have smooth, rubbery skin and are usually colored in some mixture of black, white, and gray. They have two flippers, or fins, on their sides, as well as a triangular fin on the back. Like other whales, they have an insulating layer of blubber (fat) beneath the skin.
4.The head is quite large and features a pair of ridges that run from the eyes along the center of the snout. The scales are oval and the scutes (bony plates) are small compared to other species. Young saltwater crocodiles are pale yellow with black stripes and spots found on the body and tail.

1.Adaptations for Water
Fish have gills that allow them to “breathe” oxygen in water. ... They are typically long and narrow, which reduces water resistance when they swim. Most fish have several fins for swimming. They use some of their fins to propel themselves through the water and others to steer the body as they swim.
2.They are adapted for aquatic life, with webbed feet or flippers and a streamlined body. Sea turtles rarely leave the ocean, except to lay eggs in the sand. Freshwater turtles live in ponds and lakes, and they climb out of the water onto logs or rocks to bask in the warm sun. Tortoises are land animals.
3.Dolphins are aquatic mammals that have evolved from land animals to ocean animals. Physical adaptations include a blowhole located at the top of the body, which allows a dolphin to come up to the surface, easily take in air, and continue swimming. While asleep, half of a dolphin's brain remains awake.
4.There are special bony flaps in the throat which allow a crocodile to eat when submerged or breathe when its jaws are open underwater. Crocodilians, being cold-blooded reptiles, have to avoid extremes of temperature. When it is fairly cool, they rest on a waterside bank, allowing the sun to warm their body.
