WOW! Photo, February 2004
Tiger snake eel, (Scuticaria
tigrina)
Photo by Kobus Landsberg.
Kobus describes his encounter:
" I was diving at Aliwal Shoal on the 2nd of
January 2004, in a fairly strong North-South current. I found the eel at 15m.
The water temp 23 Degrees C. It was swimming in the open and was not afraid of
us at all ".
Underwater photographer, Kobus Landsberg,
recently photographed this tiger snake moray, Scuticaria tigrina, at
Aliwal Shoal. This is a new distribution record, it was previously known south
to Sodwana. Scuticaria tigrina is widely distributed from the islands of
the eastern Pacific to Africa. It has been reported in the Western Indian Ocean
from South Africa, Mozambique, Tanzania, Oman and Mauritius. The tiger snake
moray is an uncommon species that is rarely seen.
Snake morays of the genus Scuticaria have a short rudimentary tail
restricted to the tail tip. The upper and lower jaws are approximately equal,
with the eye about midway between the snout tip and the corner of the mouth
(rictus). If the anus was visible it would be found well past the mid-length of
the body. Scuticaria have small, sharp teeth.
The eel most likely to be confused with the tiger snake moray is the
large-spotted snake moray, Uropterygius polyspilus, which has a
strikingly similar colour pattern. The two are readily distinguished with
specimens in hand by the anus of S. tigrinus being more than two-thirds
the total length from the snout and by having the inner row of teeth extending
only about halfway back in the jaw. U. polyspilus has its anus about mid
total length and has larger and fewer teeth, with the inner row reaching nearly
as far back as the outer row. If only the head is visible the eye of the tiger
snake moray is over or in front of the length of the mouth; the large-spotted
snake moray has an eye over the rear half of the mouth length.
Tiger snake morays are pale cream to yellowish brown with large, irregular,
well spaced, dark brown spots; the snout and jaws have small dark spots. They
are reported to attain 140 cm.
