Explanation
The largest invertebrate known to science is the giant squid. This animal belongs to the phylum Mollusca and the class Cephalopoda. It is famous for its enormous size, with some individuals reaching lengths of more than ten meters, including their long feeding tentacles. Because it has no backbone, it is classified as an invertebrate, and among all invertebrates, it is considered the largest. The giant squid lives in deep ocean waters and is rarely seen alive, which makes it a mysterious and fascinating animal.
