The study of molluscs is called malacology. Octologists are ear specialists (no, really). I've never heard of a term specific to octopus scientists, except for Dr. Octopus. Coming up with a proper term might be a good assignment for your students.
Octopod \Oc"to*pod\, n. [Gr. ? eight-footed; 'oktw` eight +
poy`s, podo`s, foot: cf. F. octopode.] (Zool.)
One of the Octocerata.
