''Biffarius'' is a genus of ghost shrimp in the family Callianassidae, containing species formerly included in the genus ''Callianassa''. Its members are small and generally live in the intertidal zone. In April 2020, a new species was described from the northeastern Brazilian coast. ''Biffarius'' was named in honour of Thomas A. Biffar, and includes the following species: *''Biffarius arenosus'' (Poore, 1975) *''Biffarius biformis'' (Biffar, 1971) *''Biffarius botterae'' (Hernáez, Miranda & Tavares, 2020) *''Biffarius ceramicus'' (Fulton & Grant, 1906) *''Biffarius debilis'' Hernandez-Aguilera, 1998 *''Biffarius delicatulus'' Rodrigues & Manning, 1992 *''Biffarius filholi'' (A.

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] |
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] |
Callianassa
''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. Milne-Edwards, 1861 *''Callianassa amplimaxilla'' Sakai, 2002 *''Callianassa anoploura'' Sakai, 2002 *'' Callianassa aqabaensis'' Dworschak, 2003 *'' Callianassa australis'' Kensley, 1974 *''Callianassa bangensis'' Sakai, 2005 *''Callianassa batei'' Woodward, 1869 *''Callianassa brachytelson'' Sakai, 2002 *''Callianassa brevirostris'' Sakai, 2002 *''Callianassa chakratongae'' Sakai, 2002 *''Callianassa contipes'' Sakai, 2002 *''Callianassa costaricensis'' Sakai, 2005 *''Callianassa diaphora'' Le Loeuff & Intes, 1974 *''Callianassa exil ...

Pennsylvanian (geology)
The Pennsylvanian ( , also known as Upper Carboniferous or Late Carboniferous) is, in the International Commission on Stratigraphy, ICS geologic timescale, the younger of two period (geology), subperiods (or upper of two system (stratigraphy), subsystems) of the Carboniferous Period. It lasted from roughly . As with most other geochronology, geochronologic units, the stratum, rock beds that define the Pennsylvanian are well identified, but the exact date of the start and end are uncertain by a few hundred thousand years. The Pennsylvanian is named after the U.S. state of Pennsylvania, where the coal-productive beds of this age are widespread. The division between Pennsylvanian and Mississippian (geology), Mississippian comes from North American stratigraphy. In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian.
