| Conservation Officer's Report June 99 New research by scientists in Australia shows that elephants
are descen ded from a sea creature that
used its trunk as a snorkel. They also found that elephant's lungs and kidneys
are suited to a life in the sea and that they can stay underwater for long
periods. It is thought that the trunk evolved as an adaptation to an aquatic
environment. An Indian elephant may weigh from 4 to 5 tons but they can glide
through the water with surprising elegance and can swim faster than a human
being.
A fisherman noticed a small Minke Whale
stranding itself at Penberth Cove at 5.30 in the morning on Wednesday 26th of
May, but early attempts to re-float it failed when the young 14 ft Whale turned
for shore again. As the tide went out it was left high and dry
amid the large boulders at the top of the beach. Rescuers erected shades and
kept it wet in an effort to keep it cool until the tide returned. The baby
whale became frightened and struggled violently when it became buoyant and
divers in the water had to confine it between inflatable booms until it calmed
down. They then took ft out to sea still confined and ft was successfully
released. It is considered that the young whale may have taken to the shore in
fear of Killer Whales in the area. Males can grow to about 30 ft and females to
27 ft. Known also as the Piked Whale ft is the smallest of the rorquals.
Fred and Lutz have gathered me a few samples of
plankton during the past month from various sites between
the Brisons and Low Lee and viewed under the microscope nearly all of the
creatures found jumping about have been Calanoid Copepods of various species,
but it has also been full of wonderfully coloured phytoplankton, Pennate and
Centric diatoms.
A very large Leatherback
Turtle was found entangled in the rope of a crab pot marked buoy off Slinke
Dean at 7.30 am. on the 1st of June. Several attempts were made to free ft but
each time the turtle submerged. Eventually it was set free by cutting the rope.
Another large turtle, presumably Leatherneck was seen off Fowey on May 3rd.
Mike reports that there are lots of the large jellyfish, Rhizostomapulmo around
so there may be more turtles also. Two other Turtle carcasses were found on
Cornish Beaches in March, the first at Chapel Porth near Loggerhead Turtle
St.Agnes on March 16th was a Leatherback measuring 55" x 36" across
the carapace and the other was a Loggerhead measuring only 11" long at
Perranporth on March 27th
I am at present entering data about the
sightings of Dolphins, Whales, Basking Sharks
etc. onto a database on my P.C. for Seaquest Southwest and it is interesting to
note the progress of certain animals around the coast; for instance, one
observer will notice a single Killer Whale moving West off Gwennap Head at a
certain time and another observer will send in a report of a single Killer
Whale passing Cape Cornwall about half an hour later. Progress can also be
followed of a small pod of dolphins containing an individual known as Benty,
easily recognized because of its bent over dorsal fin. That pod was in the
Helford on May 9th, moved up to Plymouth by 12th and back to Fowey by the 19th
, proceeding west to Low Lee by 2Oth May. There have been a dozen sightings of
Bottlenosed Dolphins since my last report the latest being Four off Mousehole
playing to a large audience on the pier on June 1st. and later that day at the
Minack theatre when they entertained the audience during the interval. Basking
sharks are being regularly reported, I have had reports ranging from
Charlestown to Sennen the latest being on Sunday when two were seen at the
Runnelstone from the dive boat. Cetacean stranding's of dead animals seem to
have tapered off there have been none reported in May. Total to date for
Cornwall this year being 45, much the same as this time last year.
