Odontophora sp.

Several Odontophora species occur along the Dutch Coast. These nematodes, with a length of 2 – 3 millimeter  are provided of a mouth cavity with six impressive teeth. The mouth cavity is protrusable by which the teeth, usually inside the mouth cavity, can be seen. Almost nothing is known regarding their way of life. We might assume that the teeth play a role in food consumption but the food consists of algae or animals is still unknown.  In contradiction to terrestrial nematodes, marine nematodes as this Odontophora,  are often provided of setae or small hairs and horseshoe shaped organs, the so called amphids.
