To which of the following clades does this organism most likely belong? A) CephalopodaB) ChelicerataC) BivalviaD) ErrantiaE) Polyplacophora

Cephalopoda

Explanation:

Cephalopods are commonly known as inkfishes.

But cephalopods are not at all fishes. They are molluscs.

They belong to Class Cephalopoda of phylum Mollusca.

Like other molluscs, these are also soft bodied, but have a series of tentacles that actually developed from theprimitive foot.

Cephalopods have a well developed nervous system and have large bulging eyes.

Examples of cephalopods are, octopus, giant squid etc.

Considering all the above characteristics, we can conclude that the predator stated in the question is most likely to belong to the clade cephalopoda.
