The recent Invertebrate Wars reminded me of spectacular, but often ignored, group of gastropods. The parasites! This is a group that I have totally geeked out on in the past. In my previous work I have focused on the Ptenoglossa likely a paraphyletic or polyphyletic group, established originally of unspecified rank by Gray (1853).

In most classes of Mollusks, the buccal cavity contains a tongue called the odontophore. The odontophore possess multiple rows of teeth called radula that chitonous and flexible. Among Mollusks the number of teeth can range from a few to over 100,000. The size, . . . → Read More: On How Mollusks are Cooler Than Echinoderms (or anything else) Pt. 3: The Radula

I just happen to have data sitting on my computer to address that issue. Don’t ask…I lay awake at night thinking about the body size of marine organisms.
