Kudoa sp. (Myxozoa) causing a post-mortem myoliquefaction of North-Pacific giant octopus Paroctopus dofleini (Cephalopoda: Octopodidae).

Abstract

A myxosporean belonging to the genus Kudoa was found from a North-Pacific giant octopus P. dofleini (Cephalopoda) caught in Japan exhibiting muscle degeneration, often referred to as postmortem myoliquefaction in the arm. The spores were 6-8 µm in diameter and possessed 4 pyriform polar capsules. This is the first report of a myxosporean infection in an octopus.
