Cherax parvus is a species of crayfish in the family Parastacidae. It is only known from its type locality – the Upper Tully River catchment in the Cardwell Range of north-eastern Queensland – and is listed as data deficient on the IUCN Red List. It was discovered in a rainforest catchment in a highland of northeastern Queensland during a Queensland Museum expedition to the upper Tully River area in November 1992. It is one of the smallest species in the genus. No species of Cherax has been considered endemic to wet upland or highland areas before it was discovered; most previous records were from elevations less than 400 meters. It also has several morphological features unique to the genus, and does not appear closely related to any extant species, suggesting a long period of geographic isolation.
Parribacus japonicus, the Japanese mitten lobster, is a species of slipper lobster. Though the common name for this lobster is the Japanese mitten lobster, it is locally called zōri-ebi (ゾウリエビ) – zōri denoting the Japanese sandal it resembles, and ebi meaning shrimp or lobster.
Xantho hydrophilus, the furrowed crab or Montagu's crab, is a species of crab from the family Xanthidae. It is yellowish-brown and grows to a carapace width of 70 mm (2.8 in). It is a nocturnal omnivore that lives in shallow marine waters from western Scotland to the Cape Verde Islands.
Geryon trispinosus is a species of crab that lives in deep water in the north-eastern Atlantic Ocean.
Chaceon crosnieri is a species of crab.
Chaceon bicolor is a species of crab. Chaceon bicolor differs from all species of the genus in color pattern, with the anterior part of the body purplish rather than reddish. In addition to color pattern, C. bicolor also differs from C. granulatus in having compressed rather than depressed dactyli on the walking legs; also, the hepatic region of the carapace in C. granulatus is coarsely granular, whereas it is smooth in C. bicolor. Juvenile specimens differ from adults in many features: the teeth of the carapace are much larger and sharper, there is a sharp spine on the carpus of the cheliped and a distal spine on the merus of each walking leg, plus the legs are longer and slenderer. Adult females differ from males in having much sharper anterolateral teeth on the carapace, sharper suborbital spines, and much shorter legs, with less trace of a distal dorsal projection on the merus. The carapace of females is more strongly arched from front to back and the protogastric regions are noticeably more inflated. The species is named as such because of its colour patter, purple an tan.
Chaceon atopus is a species of crab. This species resembles C. gordonae, from the Cape Verde Islands and Sierra Leone, in many features: its large size, well-developed frontal and
Lauridromia intermedia is a species of crab in the family Dromiidae and is native to the western Indo-Pacific. It often carries a piece of sponge on its back by way of camouflage, and one individual was found carrying a sea anemone in a similar manner.
Alpheus tricolor is a crustacean belonging to the family of snapping shrimp. It was first isolated in Indonesia and Sri Lanka. It counts with a setose carapace, an acute rostrum, shallow adrostral furrows and a basicerite with a strong ventrolateral tooth. The lamella of its scaphocerite is not reduced, with an anterior margin that is concave. Its third maxilliped counts with an epipodial plate bearing thick setae, while its first chelipeds are found with their merus bearing a strong disto-mesial tooth; its third pereiopod has an armed ischium, with a simple and conical dactylus. Its telson is broad, distally tapering, with 2 pairs of dorsal spines. The species is named after its characteristic colour pattern, including white, red and orange.
Myra fugax is a species of crabs in the family Leucosiidae.
Eurynome aspera, the strawberry crab, is a species of crab in the family Majidae.It is small (1–2 cm) and sometimes a vague strawberry colour. The carapace and legs are often encrusted with algae and mud which act as camouflage.
Actea savignii is a species of Indo-Pacific crab from the family Xanthidae which is one of the spiny-legged rock crabs. It has colonised the Levantine Sea by Lessepsian migration through the Suez Canal from the Red Sea since the mid 2000s.
Ashtoret lunaris, also known as the yellow moon crab, spotted moon crab or box crab, is an Indo-Pacific species of carnivorous crab which is a member of the family Matutidae. It has been recorded in the eastern Mediterranean since 2010, probably reaching that sea through the Suez Canal from the Red Sea by Lessepsian migration.
Automate branchialis is a species of pistol shrimp from the family Alpheidae which was thought to be a Lessepsian migrant, i.e. a species which had colonised the Mediterranean from the Red Sea via the Suez Canal. This was because before its description in 1958 all the species of the genus Automate were found in the Indo-Pacific region. A. branchialis has not been recorded in the Indo-Pacific region and has been found to be widespread in the Mediterranean so it is now considered to be a Mediterranean endemic.
Hyastenus hilgendorfi is a species of spider crab from the family Epialtidae, classified in the sub-family Pisinae, from the Indo-Pacific region. It has been recorded in the Suez Canal and there have been a few records in the eastern Mediterranean, making it a Lessepsian migrant.
Notopus dorsipes is a species of frog crab from the family Raninidae which has an Indo-Pacific distribution and which has recently spread into the eastern Mediterranean. It is the only extant species in the genus Notopus.
Ixa is a genus of Indo-Pacific pebble crabs from the family Leucosiidae. The genus was erected by William Elford Leach in 1816. One species, the Red Sea pebble crab, is a Lessepsian migrant and the species was first described to science from specimens collected on the Mediterranean Sea although the species is native to the Red Sea and had colonised the eastern Mediterranean through the Suez Canal.
Charybdis longicollis, the lesser swimming crab, is a species of crab from the swimming crab family, the Portunidae. It has a native range which covers the north-western Indian Ocean and it has invaded the Mediterranean Sea by Lessepsian migration through the Suez Canal.
Tubuca alcocki is a species of fiddler crab. Its range includes most of the northern Indian Ocean, from western Thailand, through the Bay of Bengal and India, to the Red Sea.
Leptuca terpsichores, commonly known as the dancing fiddler crab, is a species of fiddler crab native to the eastern Pacific coast of the Americas, from Nicaragua to Peru.
