Answer:

[tex][/tex] Write some characteristics of fishes.

Some characteristics of fishes are as follows -

1. Water habitats - Live in water their entire lives.
2. Vertebrates - have a backbone, and some cartilaginous fish have vertebrae made of cartilage rather than calcium-hardened bone.
3. Gills to breathe - Gills, which are slits on both sides of fish that allow for respiration, or the exchange of oxygen and carbon dioxide.
4. Fins for Movement - Fins are an almost universal characteristic of fish. Many types of fins exist, but the most common are the tail fin, a matching pair of side fins, dorsal fins, and an anal fin.
5. Swim Bladders - All fish have a swim bladder, which is a specialized organ filled with air that helps ensure fish maintains a stable buoyancy in the water, neither sinking or floating too much.
6. All Fish Are Cold-Blooded - All fish are cold-blooded, which is also called ectothermic. This means that fish are unable to regulate their body temperature, relying solely on the outside environment for temperature regulation.
