Animal Species:Ocellate Snake Eel, Myrichthys maculosus (Cuvier, 1816)

As its standard name implies, this largely tropical species is spotted.  What it doesn't convey is that the spots change with age.

Alternative Name/s

Spotted Snake Eel

Identification

The Ocellate Snake Eel has dark spots on a cream-coloured background. The arrangement of spots changes as a fish grows. Juveniles under 25 cm in length have one row of spots on the upper sides. Fish between 30 cm and 50 cm in length (such as that in the images) have spots along the midline alternating with spots on the upper sides. Fishes over 50cm in length have two or three rows of spots on the upper sides of the body and several rows of smaller spots along the lower surface.

Size range

The species grows to 1 m in length.

Distribution

It occurs in marine tropical waters of the Indo-West Pacific.

In Australia it is recorded from the offshore reefs of north-western Western Australia and the northern Great Barrier Reef south to the central coast of New South Wales.

Hi Ella,  Sorry about the lack of image on the page.  I will fix that today.  I have not heard anything about the weight of this species.  It is a slender fish and only grows to about 1 m in length, so I imagine that a big one would not weigh more than a kilogram or so.  I did a few searches on the Web without success.  Perhaps someone else can supply us with an answer.

I would have liked to know the weight of a spotted snake eel!
