Extra Ecological Information

Unidentified species of Neoparamoeba have been found in the listed parasite hosts.

Diagnosis

Small to moderate sized amoebae, somewhat flattened. Locomotion monopodial with conical, tapering subpseudopodia emerging from an anterior lobopodium. All species carry a DNA-containing body, the parasome (now known to be a eukaryotic endosymbiont) adjacent to the nucleus. Exclusively marine. Certain species are agents of amoebic gill disease in teleost fish, especially when intensively farmed, and of less well-studied infections of crustaceans and echinoderms.
