Papuadocus blodiwai is the only type of monotypic genus Papuadocus belonging to the flea crabs belongs (Amphipoda). It lives on the seabed of the Bismarck Sea off Papua New Guinea at depths of 500 to 600 meters.
features
The physique of these amphipods is flattened on the sides. They have sturdy bristles on the uropods . The species was incorporated into the flea shrimp family Maeridae when it was first described in 2015 . This family was separated from the Melitidae family in 2008 .
Papuadocus blodiwai is characterized by the fact that the first maxillae are not symmetrical, that is, the right palpus of the first maxilla differs from the left. Papuadocus is most closely related to the genus Bathyceradocus , which also has this characteristic, but in contrast to Papuadocus also has gills on the coxes of the 7th pair of striding legs . Papuadocus shows no sexual dimorphism with regard to the grasping tools of the second pair of legs.
Way of life
Papuadocus blodiwai feeds on decomposing organic material in the depths of the bathyal . All specimens of this species of amphipod collected so far have been found in the cavities of rotting tree trunks and branches. They have never been observed on the surface of the wood . Papuadocus blodiwai is believed to feed on wood. In the closely related species Bathyceradocus stephensensi , which lives in a similar habitat , remains of wood were found in the stomach contents. It is not yet known exactly how this material can be digested and whether endosymbiotic bacteria and archaea such as termites and other wood-digesting organisms play a role. Research in which the first person describing Papuadocus blodiwai , Laure Corbari , was involved, has shown the special role of endosymbiotic bacteria and archaea in the food chain of the lightless and oxygen-poor depths in the past .
