Question

What is a fish and explain its parts?

Answer 1

Fish:

Fish refer to craniate, gill-bearing aquatic animals that lack digitized limbs.

Parts of fish:

1. Scales: Like the skin on the human body, Scales protect fish from damage.
2. Eyes: A fish's eyes feature huge spherical pupils that do not vary in size.
3. Nostril: They lead to scent organs, which are usually quite sensitive, allowing a fish to sense the presence of food in the water from long distances.
4. Mouth: The mouth is used to take in food and breathe in water.
5. Gills: To take in water, a fish "breathes" by closing its gills and opening its mouth.
6. Lateral line: The lateral line is used to detect faint vibrations in the water.
