Genus
Common name: Orangutan Crab
Scientific name: Achaeus
Achaeus is a genus of crabs known for their distinctive furry appearance, which has earned them the nickname 'Orangutan Crab'. These crabs are small, typically reaching only a few centimeters in size, and are adorned with reddish-brown setae that resemble the fur of an orangutan. They are often found in association with various species of Pocillopora corals, where they blend in perfectly with their surroundings. Achaeus crabs are fascinating additions to reef aquariums due to their unique looks and behavior. They are generally peaceful and can be kept with a variety of other invertebrates and fish, but care should be taken to ensure they have appropriate hiding places and access to food.
