November was a month for the unusual.
Scuba divers captured historic video
footage of three coelacanths — a 400-millionyear-
old fish believed to be extinct until one
was found in a fisherman’s net in 1939. They
were filmed at a depth of 375 feet off South
Africa’s Sodwana Bay National Park, whose
reefs are frequented by sport divers.
The coelacanth has fleshy limb-like fins, the probable precursors of
arms and legs. It is the end-of-the-line-fish that scientists believe led to the
first four-legged, land-dwelling vertebrates.
Pieter Venter first spotted a coelacanth on a recreational dive in
October. It was the first time a diver outside a submersible craft had seen
the ancient species in its natural habitat. He took an eight-man team back
to verify the discovery. Making a dive using four different gas mixes that
gave them 15 minutes at 375 feet, they filmed three coelacanths after 12
minutes at that depth. The fish hung in the water, then lowered their
heads and became vertical as they were filmed.
The discovery was marred by the death of one diver, who died of a
cerebral embolism suffered during an uncontrolled ascent from that
depth.
The Sodwana fish is the shallowest find so far. Others were at 180
meters. The only other known population is off Indonesia’s Manado Tua
Island, which became known in 1997 when an American marine biologist
came across one in a fish market.
In Belize, the discovery was more macabre. Several divers aboard the
Nekton Pilot received a post-Halloween shock while diving Half Moon
Caye. There, on the bottom, lay a human skeleton minus part of the legs.
Caught on digital video by a diver from New Orleans, the tape was later
played for a substantial segment of the 31 guests on board. A diver with
funeral home experience guessed the body had been submerged only
three months as bits of connective tissue still seemed visible. Though
apparently reported to the Nekton’s Captain and a local airport shuttle
driver, there is no indication of any follow-up. Seems to us, a few Belizean
officials might be interested, as well. Unless, of course, another day was
being celebrated early - April 1.
