Haliplectus sp.

Haliplectus is a marine nematode which also occurs in brackish waters and even in dry soil. In Saaftinghe Land, in the south-west of the Netherlands, number of 25 million per square meter have been found. Nothing is known regarding the feeding behavior of Haliplectus but as a protrusable stylet is missing as wel as small denticles in the mouth cavity and the pharynx tube is rather narrow, we assume that it is a bacterial feeder. Remarkable is the round structure (terminal bulb) with wa well developed valvular apparatus. Plant parasites have a comparable structure, they use the structure as a pump. Is this also the case in Haliplectus or acts the structure to grind bacterial colonies?
