Idotea
Idotea is a genus of isopods in the family Idoteidae. These crustaceans are commonly known as “sea slaters” or “gribbles” and are found in marine environments worldwide. They are typically small, ranging from a few millimeters to several centimeters in length, and have a flattened, oval-shaped body. Idotea species are characterized by their segmented bodies, seven pairs of legs, and two pairs of antennae. They are herbivores and feed primarily on algae, but may also scavenge on dead organisms.
Common Names
Idotea species are commonly referred to as "sea slaters" or "gribbles." These names are often used interchangeably, though "gribbles" can also refer to other wood-boring isopods, such as Limnoria.
