Matutidae
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. Taxonomy Traditionally, this taxon contained the single genus ''Matuta'', and was considered a subfamily of the Calappidae. Now, the group is ranked as a family and six genera (four extant and two fossil) are now recognised. Although placed in the Calappoidea, it is not clear that Matutidae and Calappidae are closely related. *''Ashtoret'' Galil & P. F.

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calappa Japonica
''Calappa japonica'', also known as the Japanese shame-faced crab, is a marine species of box crab in the family Calappidae. Originally found in the waters around Japan, more recently it has been found in Africa, the Red Sea and Western Australia. Description ''Calappa japonica'' is a large crab, and has a yellow and red colouration. The length of carapace is approximately .65 times the width, with a tuberculated surface. Seven sharp teeth are located around the margins of each clypeiform expansion. Distribution and habitat This species was first discovered in Tokyo Bay, Japan. It is now known to occur in regions as far away as Africa and Western Australia, and lives in waters up to deep. as well as being found in the Red Sea. Behaviour and diet This crab is a predator, and feeds on invertebrates such as other crabs, as well as oysters and snails. It has a specially adapted right pincer which it uses to break open snail's shells. There is a large accessory tooth located at ...

Henri Milne-Edwards
Henri Milne-Edwards (23 October 1800 – 29 July 1885) was an eminent French zoologist. Biography Henri Milne-Edwards was the 27th child of William Edwards, an English planter and colonel of the militia in Jamaica and Elisabeth Vaux, a Frenchwoman. Henri was born in Bruges, in present-day Belgium, where his parents had retired; Bruges was then a part of the newborn French Republic. His father had been jailed for several years for helping some Englishmen in their escape to their country. Henri spent most of his life in France. He was brought up in Paris by his older brother Guillaume Frederic Edwards (1777–1842), a distinguished physiologist and ethnologist. His father was released after the fall of Napoleon. The whole family then moved to Paris. At first he turned his attention to medicine, in which he graduated as an MD at Paris in 1823. His passion for natural history soon prevailed, and he gave himself up to the study of the lower forms of animal life. He became a stude ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22.
