Phoresis is the name for when one organism attaches to another for the purpose of travel, and pea clams (Sphaeriidae) are masters of it. They attach to birds, fish, salamanders, and even aquatic insects like dragonflies or water boatmen to get a ride upstream. Ride on, little clams! (293)

New paper is officially out!
Ratfish have a second jaw on their foreheads - CT + histology show they’re real teeth, built from the same tissues and signals as oral teeth.

This common fish has an uncommon feature: forehead teeth, used for mating

New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...
