Which of the following fishes has no head, bone, eyes or nose?

Correct option is A

​The correct answer is (a) Jellyfish.

Explanation:

• Jellyfish are unique marine creatures that have no head, bones, eyes, or nose.
• They belong to the phylum Cnidaria and have a simple body structure consisting of a gelatinous umbrella-shaped bell and trailing tentacles.
• They rely on their nervous system and sensory organs to detect light and movement, but they lack complex organs like eyes or a centralized brain.

Information Booster:

• Jellyfish are invertebrates, meaning they do not have a backbone or any bones.
• They use their tentacles to capture prey and defend themselves, often equipped with stinging cells called nematocysts.
• Jellyfish have been around for over 500 million years, making them one of the oldest living creatures on Earth.

Additional Knowledge:

• Catfish: Catfish have heads, bones, eyes, and noses. They are a diverse group of fish known for their whisker-like barbels.
• Starfish: Starfish (or sea stars) have a central body and arms but lack a head, bones, or a nose. However, they have simple eyespots at the tips of their arms, which distinguishes them from jellyfish.
