Question

While snorkeling you come across an organism that appears to be a mollusk. In an effort to identify the type of mollusk you make the following observations: fast moving, large eye. What type of mollusk do you believe you have found (bivalve, gastropod, or cephalopod)?

Answer 1

Cephalopods (such as octopi and squid) typically have large eyes and can move very quickly, therefore the correct answer is cephalopods.
