Tales from the Logbook--Feeding the Wolf Eel







One of the tasks I enjoy the most is feeding the wolf eel (Anarrhichthys ocellatus) in the Bird Habitat tank at the Alaska Sea Life Center.  This activity takes place at the beginning of the first part of the dive when I do a quick survey of the habitat for mussel shells, large kelp, and other debris that might get caught in the siphon used to clean the habitat surface.  I carry a large mesh goody bag to hold the items I collect.  A small side compartment contains the half dozen or so pieces of squid that I wolf eel.

As described my Milton Love, “wolf eels are marvelous eel-shaped fishes withextremely long bodies, large canines and molars, and dorsal and anal fins that taper together to form a point.  Adults are blue-gray, red-brown, or sometimes almost white, and darkly spotted (sometimes heavily, sometime not).  Females are sometimes brownish….Adults live over reefs or around hunks of human-made material.  You mostly see the adults with their heads sticking out of crevices and caves, although they will go out for undulating sojourns on occasion.”

Bird Habitat hosts a long rock-covered den near the side viewing window.  I seldom see the wolf eel, which is about four to five feet long, swimming freely the habitat.  Rather, she resides in the den face near one opening, tail near the other.  Taking one piece of squid out of the bag at a time, I dangle it near the opening of the den to coax her out.  Most of the time, she emerges from the den and pursues the squid that I hold in my fingertips.  Other fish in the habitat may try to move in on the morsel but the wolf eel is pretty adept at getting the squid.  Soon, all the pieces of squid are consumed and the wolf eel returns to its lair as quickly as it emerged. 

If guests have been watching the feeding, I turn to them hold up my gloved hand which held the squid, and with the index finger of the other hand count my five fingers and then pass my wipe my hand across my forehead to show relief that all five digits are intact.  It is a bit of a shtick, but the kids seem to really like it. 

Sometimes the wolf eel will not eat what is offered.   She generally refuses all food when she is fecund with eggs.  During that time, usually around October, we don’t attempt to feed her.
