Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories. They first appeared in the Tithonian age of the Late Jurassic epoch, 145–152 million years ago.
Petrolisthes is a genus of marine porcelain crabs, containing these extant species:
The Galatheidae are a family of squat lobsters.
Munidopsis serricornis is a species of squat lobster. It is widely distributed in the world's oceans, being found in the eastern Atlantic Ocean, the western Atlantic Ocean, and the Indo-Pacific. It grows up to a carapace length of 20 millimetres (0.8 in).
Galathea intermedia is a species of squat lobster in the family Galatheidae. It is found in the north-eastern Atlantic Ocean, as far north as Troms, Norway, south to Dakar and the Mediterranean Sea.
Galathea strigosa is a species of squat lobster in the family Galatheidae. It is found in the northeast Atlantic Ocean, from the Nordkapp to the Canary Islands, and in the Mediterranean Sea and Red Sea. It is edible, but not fished commercially. It is the largest squat lobster in the northeast Atlantic, reaching a length of 90 millimetres (3.5 in), or a carapace length of 53 mm (2.1 in), and is easily identified by the transverse blue stripes across the body.
Munidopsis is a genus of squat lobster. It is the second largest of all the genera of squat lobsters, after Munida, with over 200 species. Its members are mainly found on continental slopes and on abyssal plains. A few fossil species are also known, including specimens from the Campanian (Cretaceous). More species are being discovered as deep-sea exploration becomes more accessible.
Munida is the largest genus of squat lobsters in the family Munididae, with over 240 species.
Nanogalathea raymondi is a species of squat lobster from the Bay of Bengal. It is the only species in the genus Nanogalathea. It can be distinguished from other squat lobsters by the lack of any teeth along the edge of the rostrum. The specific epithet raymondi commemorates the carcinologist Raymond B. Manning.
Chirostylus is a genus of squat lobsters in the family Chirostylidae, containing the following species:
Uroptychus is a genus of squat lobsters in the family Chirostylidae found across the Indo-Pacific. The genus Uroptychus contains the following species:
Bathymunida is a genus of squat lobsters in the family Munididae, containing the following species:
Coralliogalathea is a genus of squat lobsters in the family Galatheidae. Initially thought to be monotypic, solely represented by Coralliogalathea humilis, recent analysis has split the genus into six, morphologically similar but genetically different species.
Fennerogalathea is a genus of squat lobsters in the family Galatheidae, containing the following species:
Lauriea is a genus of squat lobsters in the family Galatheidae, containing the following species:
Phylladiorhynchus is a genus of squat lobsters in the family Galatheidae, containing the following species:
Raymunida is a genus of squat lobsters in the family Munididae, containing the following 11 species:
The Galatheoidea are a superfamily of decapod crustaceans comprising the porcelain crabs and some squat lobsters. Squat lobsters within the three families of the superfamily Chirostyloidea are not closely related to the squat lobsters within the Galatheoidea. The fossil record of the superfamily extends back to the Middle Jurassic genus Palaeomunidopsis.
Pilumnus is a genus of crabs, containing the following species:
Lauriea siagiani, is a species of squat lobster in the family Galatheidae, genus Lauriea.
