The Spionidae (Polychaeta) act as invertebrate hosts for marine Myxozoa

Actinosporean stages including spherical pansporocysts and oval tetractinomyxon actinospores about 8 μm long were found in two unidentified spionid polychaetes in the northern Øresund, Denmark. The myxosporean stages in fish are unknown. Members of the Spionidae occur worldwide and at all depths and it is likely that they act as invertebrate hosts for several species of Myxozoa. *Corresponding ...

Spionidae (Annelida: Polychaeta) from the Parque Nacional Morrocoy, Falcón, Venezuela.

Five species of polychaetes (Spionidae) were found associated to Thalassia testudinum meadows in Parque Nacional Morrocoy, Venezuela. We included a guide for their identification and present range extensions for the Venezuelan coasts and Southern Caribbean Sea. The species are: Dipolydora socialis, Prionospio (Minuspio) cirrifera, P. (Prionospio) fallax, P. (P.) steenstrupi, and Spio pettiboneae.

Spionidae (Polychaeta: Canalipalpata: Spionida) from seamounts in the NE Atlantic.

Spionidae (Polychaeta) collected from seamounts in the Atlantic Ocean were studied. Altogether six species were found of which two are new to science and one belongs to a new genus. Aonidella cf. dayi Maciolek in López-Jamar, 1989 and Glandulospio orestes gen. et sp. nov. were the most common species and occurred on both the Great and Little Meteor Seamount, the Irving Seamount and the Hyeres S...

Polydora nuchalis (Polychaeta: Spionidae), a New Hawaiian Record from Aquaculture Ponds!

The spionid polychaete Polydora nuchalis was collected from the mud bottoms of penaeid shrimp and oyster culture ponds at two aquaculture farms on Oahu, Hawaii. The polychaetes formed masses of mud tubes , which contained egg capsules and early and late larval stages. Polydora nuchalis is not a shell-boring worm like the congener P. websteri that infects commercial shellfish, but is considered ...
