How closely related are squid and octopus?

You wouldn't be alone if you thought the octopus and squid were the same animals. They are cousins—both part of the group cephalopoda—a group of marine mollusks that include squid, octopus, nautilus, and snails. The largest cephalopod is the giant squid and the smallest being the pygmy squid.

What role does the octopus play in the ecosystem?

Octopuses play a key predatory role in shaping communities that is unmatched by any other invertebrate. Additionally, their “live fast, die young” life history strategy means their populations respond quickly and dramatically to changes in the environment, which suggests they could be an indicator of ecosystem change.

What is squid ecosystem?

Is a squid a predator or prey?
