Many thanks to the underwater photographer, Barry Brown for using the image Pylopagurus discoidalis (called“The Three Amigos” )in our on-line encyclopediathe!
Thomas Wiewandt : "Three rare, deep water hermit crabs (Pylopagurus discoidalis) living in discarded tusk-shells. These 2-3-inch specimens were discovered and collected between 700-1000 feet by a manned submersible called the Curasub. The most striking feature of the animal is it's chelae, a shield-shaped appendage that allows it to firmly seal it's shell when alarmed or threatened. BAR-2535 shows these crabs in their "alarmed mode". Substation Curacao, Curacao Sea Aquarium, Curacao, Netherlands Antilles.”
Pylopagurus discoidalis is an unsually hermit crab, a deep sea hermit crab with a shield-shaped appendage.
The Tusk Shell Hermit Crab has a tube-shaped body and a shield-shaped appendage. Pylopagurus discoidalis needs a tusk shell (Scaphopoda)for housing.Both ends of the tusk shell can be sealed by shield-shaped appendage and the body.
The animals were found at a depth of 50 to 305 m.
