Pestarella
''Pestarella'' is a genus of thalassinidean crustacean erected in 2003 from former members of the genus ''Callianassa''. It is distinguished from ''Callianassa'' by the rounded, rather than squarish telson, and by the absence of the first two pleopods in males.

Pestarella Tyrrhena
''Gilvossius tyrrhenus'' (formerly ''Pestarella tyrrhena'') is a species of thalassinidean crustacean (''ghost shrimp'' or ''mud shrimp'') which grows to a length of . It lives in burrows in shallow sandy parts of the sea-bed in the Mediterranean Sea and northern Atlantic Ocean. It is the most common thalassinidean in the Mediterranean, and has been used as bait by fishermen for at least 200 years. Description ''G. tyrrhenus'' is a small crustacean, up to long, with a soft exoskeleton apart from two large, unequal claws. It is whitish or greenish-grey, with pink or blue spots. Because of its burrowing lifestyle, ''G. tyrrhenus'' has small eyes on short stalks, and its maxillipeds can form an operculum; the telson is very short, and the rostrum is almost entirely absent. Larval development is rapid and involves few stages. Eggs hatch into a zoeal stage, which is followed by a second zoea and then a megalopa stage before adulthood. This rapid development allows the larvae to se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callianassa (genus)
''Callianassa'' is a genus of mud shrimps, in the family Callianassidae. Three of the species in this genus ('' C. candida'', '' C. tyrrhena'' and '' C. whitei'') have been split off into a new genus, '' Pestarella'', while others such as '' Callianassa filholi'' have been moved to '' Biffarius''. Species Forty-six species are currently recognised in the genus ''Callianassa'': *'' Callianassa acutirostella'' Sakai, 1988 *'' Callianassa affinis'' A.

Thalassinidea
Thalassinidea is a former infraorder of decapod crustaceans that live in burrows in muddy bottoms of the world's oceans. In Australian English, the littoral thalassinidean ''Trypaea australiensis'' is referred to as the ''yabby'' (a term which also refers to freshwater crayfish of the genus ''Cherax''), frequently used as bait for estuarine fishing; elsewhere, however, they are poorly known, and as such have few vernacular names, "mud lobster" and "ghost shrimp" counting among them. The burrows made by thalassinideans are frequently preserved, and the fossil record of thalassinideans reaches back to the late Jurassic. The group was abandoned when it became clear that it represented two separate lineages, now both recognised as infraorders: Gebiidea and Axiidea. Recent molecular analyses have shown that thalassinideans are most closely related to Brachyura (crabs) and Anomura (hermit crabs and their allies). There are believed to be 556 extant species of thalassinideans in 96 gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decapoda
The Decapoda or decapods (literally "ten-footed") are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crabs, lobsters, crayfish, shrimp and prawns. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs, porcelain crabs, squat lobsters (about 2500 species) making up the bulk of the remainder. The earliest fossil decapod is the Devonian ''Palaeopalaemon''. Anatomy Decapods can have as many as 38 appendages, arranged in one pair per body segment. As the name Decapoda (from the Greek , ', "ten", and , '' -pod'', "foot") implies, ten of these appendages are considered legs. They are the pereiopods, found on the last five thoracic segments. In many decapods, one pair of these "legs" has enlarged pincers, called chelae, with the legs be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
