Prostoma Jenningsi
''Prostoma jenningsi'' is a species of ribbon worm known only from one site near Croston, Lancashire. It was described in 1971, and is believed to be the county's only endemic species. It grows up to long, with 4–6 black eyespots, and has a long eversible proboscis. Distribution The only site where ''P. jenningsi'' has been found is a former clay pit now used for recreational fishing between Bretherton and Croston in Chorley borough, Lancashire. It was discovered there in 1967, and described by Ray Gibson and Johnstone O. Young in 1971. It is thought to be the only species endemic to Lancashire. Prior to the discovery of ''P. jenningsi'', there had only been four reports of freshwater nemerteans in the British Isles, in the River Cherwell at Oxford, the River Cam at Cambridge, a tank in Regent's Park, London, and the Grand Canal at Clondalkin, County Dublin. Description ''Prostoma jenningsi'' is a slender worm, with an elliptical cross-section. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stylet (anatomy)
A stylet is a hard, sharp, anatomical structure found in some invertebrates. For example, the word ''stylet'' or stomatostyle is used for the primitive piercing mouthparts of some nematodes and some nemerteans. In these groups the stylet is a hardened protrusible opening to the stomach. These stylets are adapted for the piercing of cell walls and usually function by providing the operative organism with access to the nutrients contained within the prey cell. The mouthparts of tardigrades, diptera and aphid Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A t ...s are also called stylets. In octopodes, the stylets are internal, needle-like bent rods within the mantle, the vestigial remnants of an external shell. References Nematode anatomy {{Animal-anatomy-stub ...
