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.
