yes,they are.I know because they can lay eggs in places many other animals cant.(water animals)
fish and water snakes
Vertebrates are animals with a backbone, so some vertebrates live in water (e.g. fish) but others live on land (e.g. cows).
A bird is similar to a fish in that they both make eggs. They are also from the same kingdom chordates and are both vertebrates.
Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
They need moist on there scales and they eat fish
The main way fish differ from other types of vertebrates are they live in/under water. Also fish have scales.
Gills, fins, and scales.
They have scales and dont live long out of water they breathe through gills. Yes, but you are illiterate. Know*
Fish have specialized parts (gills, fins, scales, for example) that enable the fish to live and breathe under water.
Scales can help to protect a fish and make it more comfortable when it swims or moves around; scales are typically hard, sturdy, and slippery which can also make it more difficult for predators to catch it.
