[1] It has been observed in the muscles of the dagger-tooth pike conger Muraenesox cinereus, a muraenesocid marine fish off Japan.

[1] The parasite was detected by the presence of small black spots, 1–2 mm in diameter, in the flesh (muscles) of fish; these black spots are accumulations of eggs.

The nematode was differentiated from other members of the genus Huffmanela by the dimensions of its eggs and the characteristics of their surface.

It is the single Huffmanela species which is parasitic in a fish of the family Muraenesocidae.

Since Huffmanela hamo is a parasite of the flesh and the fish is consumed by humans, it is useful to remind that species of the genus Huffmanela do not infest humans, and thus the consumption of infected fish is harmless.
