Halicryptidae

	Halicryptidae ''Halicryptus'' is the sole genus of its class of priapulid worms, and has an important effect on the structure of soft-sediment communities. This genus contains the following species: * '' Halicryptus higginsi'' * '' Halicryptus spinulosus'' - type species ''Halicryptus spinulosus'' exhibits a wide distribution around the Arctic Ocean and can reach lengths of 4 cm as adults, while the distribution of ''Halicryptus higginsi'' appears to be restricted to the Beaufort Sea near Point Barrow, and can grow to about 40 cm, the largest known priapulids, even if 20 cm long adults are more common. Halicryptus spinulosus Halicryptus spinulosus is a species of priapulid worm found in marine environments. It is a macrobenthic priapulid living in disjunct subarctic brackish seas, including the White Sea, waters off Iceland, northern Siberia and Alaska, and in an outlying range in the Baltic Sea. Known for its distinctive spiny appearance, this worm plays a role in the benthic ecosyste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Priapulid Priapulida (priapulid worms, from Gr. πριάπος, ''priāpos'' 'Priapus' + Lat. ''-ul-'', diminutive), sometimes referred to as penis worms, is a phylum of unsegmented marine worms. The name of the phylum relates to the Greek god of fertility, because their general shape and their extensible spiny introvert (eversible) proboscis may resemble the shape of a human penis. They live in the mud, except for a few tropical meiobenthic species which live in medium- to coarse-grained sands, and are found in comparatively shallow waters to deep waters and no warmer than 12–13°C. Some species show a remarkable tolerance for hydrogen sulfide, anoxia and low salinity. ''Halicryptus spinulosus'' appears to prefer brackish shallow waters. They can be quite abundant in some areas. In an Alaskan bay as many as 85 adult individuals of '' Priapulus caudatus'' per square meter has been recorded, while the density of its larvae can be as high as 58,000 per square meter (5,390 per square foot). ...
