April 25, 2008 -- What's black and white and warm all over? A penguin in a wetsuit, naturally.
Sounds
like a joke, but it's quite serious for biologists at the
California Academy of Sciences, who had a wetsuit created for an
African penguin to help him get back in the swim of things. Pierre, a venerable 25 years old, was going bald, which left him with an embarrassingly exposed, pale pink behind.
Unlike marine mammals, which have a layer of blubber to keep them warm,
penguins rely on their waterproof feathers.
Without them, Pierre was unwilling to plunge into the academy's penguin
tank and ended up shivering on the sidelines while his 19 peers played
in the water. "He was cold; he would shake," said Pam Schaller, a senior aquatic
biologist at the academy.
Pierre's species of penguin is accustomed to temperate climates, unlike
many of their cousins. The birds are nicknamed Jackass penguins because
they make sounds similar to braying donkeys, quite startling the first
time you hear it in an aquarium.
Schaller first tried a heat lamp to keep Pierre warm. Then she got
another idea: If wetsuits help humans frolic in the chilly Pacific, why
not whip up one in a slightly smaller size?
Staff at Oceanic Worldwide, a supplier of dive gear based in San
Leandro, were enthusiastic about making a real penguin suit.
"We were really excited to do it," said Teo Tertel, company marketing
specialist. "We heard most of these penguins only live to 20, and our
little buddy there was already 25. Anything we could do to help them,
we were all for it."
Schaller conducted fittings to design the suit, which fastens with
Velcro at the back, covers Pierre's torso and has small openings for
his flippers. "I would walk behind him and look at where there were any gaps, and cut
and refit and cut and refit until it looked like it was extremely
streamlined," she said.
One concern was that the other penguins would reject Pierre in his new duds, but in fact, they accepted his sleek new look. Pierre was outfitted with the suit about six weeks ago. Since then, he
has gained weight, grown back feathers on his hind parts and is again
acting like his feisty, alpha-male self.
On a recent visit, Pierre waddled around the tank, taking brief dips
and standing on a rock next to his mate. He blended in well, although
he was the only penguin with a black tummy.
Schaller can't say for sure whether the wetsuit allowed Pierre to
recover his fine feathers, but "certainly we were able to keep him
comfortable during a period of time that would have been very difficult
for him to stay comfortable." With his plumage restored, Pierre is being weaned off the suit, taking more and more dips in the buff.
There are no plans to make him a matching surf board.
