Giant Squid Vs Sperm Whale!

Like all squid, the Giant Squid has a mantle, 8 arms, and 2 longer tentacles which are the longest known tentacles of any cephalopods.

The inside surfaces of the arms and tentacles are lined with hundreds of subspherical suction cups, each mounted on a stalk. The circumference of these suckers is lined with sharp, finely serrated rings of chitin.

These serve to help the squid attack and attach itself to prey.

The Giant Squid has a sophisticated nervous system, which attracted great interest from dissectors like Sebastian in his previous life and they also have the largest eyes of any living creature. 

For Sperm Whales, they are the largest of the toothed whales and the largest toothed predator. It uses echolocation and vocalization as loud as 230 decibels, which means their ability to locate objects underwater by reflected sound.

It also has the largest brain known of any modern or extinct animal.
