Aristotle’s lantern is found in____
A. Jellyfish
B. Sea anemone
C. Sea lily
D. Sea urchin

Answer 1

Hint: Aristotle’s lantern is a confusing arrangement of muscles and calcium composed teeth. Along with this, some plates help in shaping an organ in many echinoids. This structure is venomous. It is used for scraping away the algae and making resting and hiding place for the organism. It is quite a unique physical feature possessed by Marine organisms.

Complete answer:
Sea urchins have an intricately built denture on the underside of the mouth which is called Aristotle’s lantern. This denture is very strong and is u. The mouth of most of the Sea urchins is composed of five calcium carbonate in scratching algae from the hard surfaces. The teeth can also be used to uncover the hidden spots. The mouth of a Sea urchin is composed of teeth or jaws, with a fleshy, tongue-like structure.
Sea urchins are marine invertebrates belonging to the Echinoidea class. They have a globular body and a radial plan of organs, which appeared by five groups of pores running from the mouth to anus over the test. They have thin and extensible tube feet that have suckers on their tips. They live in the depths of the sea, especially near hard surfaces. They move with the help of cylinder feet or spines.
Jellyfishes do not have a feature like this because they do not require a scraping of the rock surfaces to hide. Instead, the tentacles possessed by them are poisonous which doesn’t allow predators to come near. Moreover, it has a transparent body which is a bonus to hide in case the tentacles fail.
Therefore, option (a) is not correct.
Sea anemones also belong to tentacles possessing a category of Marine organisms. But their tentacles are used to cover their upper body and hide near a rock.
Therefore, option (b) is incorrect.
Sea Lily have a feathery body and they remain attached to the corals which makes them resemble a flower. They remain hidden during the day and come out at night for predation. The most distinctive feature is that they start feeding on their own feet if they don’t get food for a long time.
Therefore, option (c) is also incorrect.
From the above explanation, sea urchins are the one’s possessing Aristotle’s lantern.
So, the correct answer is “Option D”.

Note:
Aristotle is popular for his work in philosophy and has composed numerous books. In one of his books “ Historia Animalium”, he portrayed the mouth portion of the Sea urchin. He said that the mouth mechanical assembly of Sea urchin is constant from one end to the next, yet the outward appearance is not along the lines. It resembles a horn lantern with sheets. Later the other researchers named that lantern Aristotle’s lantern.
