An animal like a rockSourced
A rocky-looking exterior hides a filter feeder
Piure, Pyura chilensis, is a tunicate found along Chilean and Peruvian shores. It resembles a mass of organs inside a rock. It draws in seawater and filters microorganisms for food, and is also harvested as food in Chile.
The rocky appearance conceals a living, feeding animal.
