Daldorfia horrida, the horrid elbow crab,[1] is a species of elbow crab in the family Parthenopidae. It is native to tropical and subtropical waters of the Indo-Pacific.
Taxonomy
Daldorfia horrida was originally classified by Carl Linnaeus as Cancer horrida in 1758. It was subsequently moved to the genus Daldorfia in 1904.[2]
Description
Daldorfia horrida is a medium-sized species of crab with a carapace approximately 12 centimetres (4.7 in) in diameter. It utilises camouflage, as its carapace resembles a rock, which allows it to avoid predators in its natural environment.[3] In addition to this, the carapace is roughly shaped like a pentagon, and covered in spines. The pincers are unequal in size and double the length of the carapace.[1]
