Question

Explain the features of fishes which help it to adapt to live in water.

Answer 1

Hint: Fishes have specialized features that allow them to survive in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water because it passes over them. Fish have a streamlined body.

Complete answer: Some of the characteristic adaptations found in fishes that allow them to survive in water are listed below:
1. Gills: Gills enable fish to soak up oxygen from the water. Fishes don't chemically break down water to derive oxygen. They absorb oxygen that's dissolved within the water.
2. Camouflage: Coloration in the form of stripes, patterns, and spots are present in fishes that help them to escape predators. This also helps them to match their background, and a few can actually change color to blend in with their surroundings.
3. Sense Organs: Light doesn't penetrate to the depths of the ocean, other senses became far more refined in fish. Some fish have much more sensitive noses, and some can detect vibrations within the water.
4. Body shape: The streamlined bodies of fishes are perfectly adapted in order for them to move through the water and navigate against the strong water currents.

Note: The primary fishes evolved about 500 million years ago, much before humans yet they are still existing even today. There’s a really good reason that fishes are still around; they're extremely well-adapted to their environment.
