Description
Grapsus grapsus is one of the most common crabs along the western coast of the Americas. It is known variously as, "red rock crab", "abuete negro", and along with crabs such as Percnon gibbesi as, "Sally Lightfoot" Grapsus grapsus is a typically shaped crab, with five pairs of legs, the front two bearing small, blocky, symmetrical chelae. The other legs are broad and flat, with only the tips touching the substrate. The crab's round, flat carapace is slightly longer than 8 centimetres (3.1 in). Young G. grapsus are black or dark brown in colour and are camouflaged well on the black lava coasts of volcanic islands. Adults are quite variable in colour; some are muted brownish-red, some mottled or spotted brown, pink,or yellow. Grapsus grapsus is found along the Pacific coast of Mexico, Central America, South America (as far south as northern Peru), and on nearby islands, including the Galápagos Islands. It is also found along the Atlantic coast of South America, but is replaced in the eastern Atlantic Ocean (Ascension Island and West Africa) by its congener Grapsus adscensionis.

Percnon gibbesi is a species of crab. It is one of at least two species commonly called "Sally Lightfoot" (the other being the semi-terrestrial Grapsus grapsus from the Pacific coast of the Americas), and is also referred to as the nimble spray crab or urchin crab. It has been described as "the most invasive decapod species to enter the Mediterranean" Adults have a carapace 30 millimetres (1.2 in) wide, and legs with yellow rings at the joints. Each of the five pairs of walking legs has a row of spines along the leading edge. Females carrying eggs have been caught off West Africa between February and April and August; the larvae which hatch from them are planktonic and long-lived, which may contribute to the species' invasiveness. P. gibbesi is one of the most widespread grapsid crabs, being found on both sides of the Atlantic Ocean and on the Pacific coast of North America. There, its range extends from California to Chile, while in the Atlantic, it occurs natively from Florida to Brazil and from Madeira to the Gulf of Guinea. It has recently invaded the Mediterranean Sea, having first been discovered at Linosa, Sicily in 1999. It has subsequently been found on the Balearic Islands, in Greece, in Libya in Malta and in Israel.

This crab is in English also called Anemone Spider Crab or Leach's Spider Crab called. Inachus phalangium, Leach's spider crab, is a species of crab from the north-eastern Atlantic Ocean and Mediterranean Sea. It is up to 20.5 mm (0.81 in) wide, and is very similar to other species in the genus Inachus. Large males may reach a carapace size of 20.5 by 17.5 millimetres (0.8 in × 0.7 in), and is brownish-yellow in colour. The carapace becomes narrower towards the front of the animal, and is often concealed by epibionts. I. phalangium resembles the closely related species Inachus dorsettensis, but has less prominent spines on the carapace. I. phalangium is found in the eastern Atlantic Ocean, from Norway in the north to West Africa and the Cape Verde islands in the south, and extending into the Mediterranean Sea. It lives at depths of 11–55 metres (40–180 ft).

Portunus is a genus of crab which includes several important species for fisheries, such as the blue swimming crab, Portunus pelagicus and the Gazami crab, P. trituberculatus. Other species, such as the three-spotted crab (P. sanguinolentus) are caught as bycatch. Fossil of Portunus convexus The genus Portunus contains more than 90 extant species and over 40 further species known only from fossils.[4] Fossils of crabs within this genus can be found in sediment of Europe, the United States, Mexico, Venezuela, Brazil and Australia from Paleogene to recent (age range: 48.6 to 0.0 million years ago).

Planes minutus is a species of pelagic crab that lives in the North Atlantic Ocean. It is typically less than 10 mm (0.4 in) long across the back, and is variable in colouration, to match its background. It may have been the crab seen by Christopher Columbus on Sargassum weed in the Sargasso Sea in 1492. Planes minutus is a small crab, reaching a maximum carapace length of 17.5 millimetres (0.7 in), and typically less than 10 mm (0.4 in). It has conspicuous eyes in wide orbits at the corners of the wide front edge of the carapace. The first pair of pereiopods (walking legs) bear a symmetrical pair of chelae with cutting teeth; the other four pairs are adorned with spines on the last two segments of each leg. It differs from the larger P. major in that males have a broadly triangular abdomen, rather than one which narrows abruptly after the third segment, and from P. marinus in having flattened legs with a fringe of setae that aid in swimming. The colouration of Planes minutus is very variable, and camouflages the crab against the Sargassum weed it often lives on. The base colour is typically brown, sometimes tending towards yellow or red. This is often supplemented with large patches of white, apparently imitating the calcareous tubes attached by annelid worms to Sargassum. Although the colour pattern tends to match that of the substrate on which the crab is found, the colouration is only able to change slowly after a change of substrate. Planes minutus is found in the North Atlantic Ocean, between the latitudes of 11° N and 32° N, and also from the west coast of Africa.

Maja squinado (the European spider crab, spiny spider crab or spinous spider crab) is a species of migratory crab found in the north-east Atlantic and the Mediterranean Sea. M. squinado feeds on a great variety of organisms, with seaweeds and molluscs dominating in winter, and echinoderms such as sea urchins and sea cucumbers in summer. Migrations generally take place in autumn, with some crabs covering over 100 miles (160 km) in eight months. All crabs are vulnerable to predation when moulting, and M. squinado becomes gregarious around that time, presumably for defense against predators. Females can produce up to four broods per year.
