Matuta planipes is a species of moon crab in the family Matutidae. [1] It is a small colorful crab with flattened limbs. [2] The Matuta planipes, in contrast to other species of crabs inhale pure oxygen-water through an area near their eye sockets. This species of crabs enjoy spending their daytime hidden under some sort of shade such as a sand bed and they are more active during the night.
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless.
Squat lobsters are dorsoventrally flattened crustaceans with long tails held curled beneath the cephalothorax. They are found in the two superfamilies Galatheoidea and Chirostyloidea, which form part of the decapod infraorder Anomura, alongside groups including the hermit crabs and mole crabs. They are distributed worldwide in the oceans, and occur from near the surface to deep sea hydrothermal vents, with one species occupying caves above sea level. More than 900 species have been described, in around 60 genera. Some species form dense aggregations, either on the sea floor or in the water column, and a small number are commercially fished.
The Christmas Island red crab is a species of land crab that is endemic to Christmas Island and Cocos (Keeling) Islands in the Indian Ocean. Although restricted to a relatively small area, an estimated 43.7 million adult red crabs once lived on Christmas Island alone, but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years. Christmas Island red crabs make an annual mass migration to the sea to lay their eggs in the ocean. Although its population is under great assault by the ants, as of 2020 the red crab had not been assessed by the International Union for Conservation of Nature (IUCN) and it was not listed on their Red List. The crab's annual mass migration to the sea for spawning is described as an "epic" event. Millions emerge at the same time, halting road traffic and covering the ground in a thick carpet of crabs.

Ocypode is a genus of ghost crabs found in the sandy shores of tropical and subtropical regions throughout the world. They have a box-like body, thick and elongated eyestalks, and one claw is larger than the other in both males and females. They inhabit deep burrows in the intertidal zone. They are primarily nocturnal, and are generalist scavengers and predators of small animals. The genus contains 21 species.
Fordonia leucobalia is an aquatic snake known by the common names crab-eating water snake and white-bellied mangrove snake. It is a common resident of mangrove swamps and tropical tidal wetlands from coast of Southeast Asia to Indonesia and the coasts of Northern Australia.

The Majoidea are a superfamily of crabs which includes the various spider crabs.
Ovalipes australiensis is a species of crab found in southern Australia. Its range extends from Western Australia to Queensland, including Tasmania. It is fished commercially and recreationally, although it is not as important as the blue swimmer or mud crab.
Matutidae is a family of crabs, sometimes called moon crabs, adapted for swimming or digging. They differ from the swimming crabs of the family Portunidae in that all five pairs of legs are flattened, rather than just the last pair, as in Portunidae. Crabs in the Matutidae are aggressive predators.
Matuta is a genus of crabs in the family Matutidae, containing the following species:
Pleuroncodes planipes, sometimes called the pelagic red crab, tuna crab or langostilla, is a species of squat lobster from the eastern Pacific Ocean.
Pyromaia cuspidata, also known as the dartnose pear crab, is a species of crab in the family Inachoididae. This crab appears similar to Anasimus latus. It is a long-legged crab with a trident-shaped rostrum, and occurs in Atlantic waters from North Carolina to west Florida, and in the Gulf of Mexico through the Yucatán Peninsula down to Nicaragua. It is also found in Cuban waters. This species lives in depths of 27–549 metres (89–1,801 ft) on bottoms of mud, sand, or pebbles.
Rhizophora mucronata is a species of mangrove found on coasts and river banks in East Africa and the Indo-Pacific region.
Portunus sanguinolentus, the three-spot swimming crab, blood-spotted swimming crab or red-spotted swimming crab, is a large crab found throughout estuaries of the Indian and West Pacific Oceanic countries.
Tubuca flammula, commonly known as the flame-backed fiddler crab is a species of fiddler crab that is found in the northwest of Western Australia, the northern part of the Northern Territory and the western half of Papua New Guinea
Austrothelphusa transversa(von Martens, 1868), also known as the inland crab, freshwater crab, or tropical freshwater crab is a species of freshwater crab endemic to Australia. A. transversa is the most widely-dispersed species of its genus, as it has adaptations giving it a high tolerance to drought and arid conditions.
Cymbacha saucia is a crab spider found in Australia. The body length of the female is up to 7 mm, the male 4 mm. A cryptic small species, the colour is usually brown, grey and black. Often found in a folded leaf, used as a retreat.
Australoplax tridentata, commonly known as the furry-clawed crab or tuxedo shore crab is a species of crab in the family Macrophthalmidae that is found in Queensland, New South Wales and the Northern Territory.
Helopgrapsus haswellianus or Haswell’s shore crab, is the sole species of crab in the genus Helograpsus. It lives in river mouths and bays on the eastern coast of Australia. The carapace is strongly convex with one distinct notch behind the eye. Adult males have larger claws than adult females. The carapace is olive, dark slate grey or reddish. Claws of adult males are orange-yellow. Carapace size is up to 30 mm wide. The orange color is stronger when these crabs live in habitat with lower pollution levels.
