      "Most fish live underwater, which is a terrible place to have sex
      because virtually anywhere you lie down there will be stinging
      crabs and large quantities of little fish staring at you with
      buggy little eyes."

This month's stories
  1) Report from the Field: De-Oiling Penguins in South Africa
  2) New Blue Debut
  3) More Fish, Please: A Marine Mammal Trainer's Day

When last we left you, two of our intrepid penguin aquarists where taking off
for South Africa to spend a few weeks removing oil from African penguins caught
in the oil spill off the coast of Cape Town. You may have been following some
of the story on our website, but if you haven't, here's the scoop:

On June 23, 2000, the oil tanker Treasure ruptured and sank six miles off the
coast of Cape Town, South Africa. The Treasure was carrying approximately 1,300
tons of fuel oil, that spread throughout the area, which, unfortunately,
happened to be the primary breeding site of African penguins, and, doubly
unfortunately, happened in the midst of the best breeding season in 25 years.

Shortly after the spill, New England Aquarium penguin experts Heather Urquhart
and Dyan deNapoli left for Cape Town to help rehabilitate some of the 55,000
penguins affected by the spill. The rescue and rehabilitation effort was
coordinated by SANCCOB, the South African National Foundation for the
Conservation of Coastal Birds and the International Fund for Animal Welfare
(IFAW). Heather and Dyan joined penguin experts and vets from several other
zoos and aquariums in the U.S. and around the world in making the journey to
Cape Town. An additional 1,000 local volunteers a day (including scores of
students on school vacation and foreign tourists) helped out with feeding,
cleaning and supervising swim times for the birds.

Approximately 21,000 adult penguins and 6,000 chicks from the two major nesting
sites, Robben Island and Dassen Island, had to be removed by boat and plane,
and transported to facilities for cleaning and care until the spill was cleaned
up. Another 34,000 penguins were rescued and relocated to clean water some
distance away. The condition of the 21,000 adult penguins picked up for
rehabilitation ranged from completely black with oil to having only minor oil
streaks to relatively clean birds that had to be removed from their homes to
prevent them from entering the water and getting oiled. Fences were even
installed around the islands to keep the birds on land until they could be
removed and brought to the rehabilitation centers.

When they arrived in South Africa, Heather and Dyan were immediately put to
work in a former train warehouse in Salt River, where they spent from 7 a.m. to
10 p.m. that day force-feeding penguins fish (6 tons of sardines per day were
donated). These wild birds were not used to being handled and were not used to
eating dead fish from a person's hand, so it was quite a challenge - and both
Heather and Dyan have the scars to prove it! For the next two weeks, Dyan
assisted Heather, who was in charge of one "room" containing 84 pens and 4,000
penguins that had to be cleaned, fed and let out to swim every day with the
help of approximately 150 volunteers.

It usually takes two people one hour to clean an oiled penguin, but with
thousands to get through, they streamlined the process to a 20-minute wash and
a 5-minute rinse. Not doing a full rinse means that some soap is left in the
feathers, and the birds need to swim to wash out the soap and regain their
natural waterproofing. After the rinse, they found that these birds needed 2-3
weeks, instead of the usual five days, before they were waterproof enough to be
returned to the wild. In the second week of their trip, Dyan moved to the
SANCCOB facility in Table View, where she supervised the husbandry and swimming
of the 4,000 birds housed there. Each of the penguins had to be "graded" to
determine if it was waterproofing its feathers sufficiently before being

The good news is that the rescuers have done pretty well - of the rescued adult
penguins, only about 1% have died. In previous spills, 85% recovery rates have
been documented. By the end of July, the oil was mostly cleaned up and the
penguins were starting to be released. The bad news is that the oil spill
caused the loss of one of the best breeding seasons ever recorded - thousands
of healthy baby chicks died or had to be euthanised without parents able to
feed them.

We thank all of you who have supported the New England Aquarium's Conservation
Action Fund, which provided funding for Heather and Dyan to make this journey
and contribute to the overall survival of this vulnerable penguin species.
Droplet: The cleanser they used to de-oil the penguins was invented by a South
African high school student for a science project last year. The formula is a
secret (he is trying to get a patent for it), but its main ingredient is
cooking oil!

----- NEW BLUE DEBUT -------------------------------------------------------
With help from Yvonne Vrugtman and Kelly McNamara, Education Interns

One of our Giant Ocean Tank's newest residents is blue - in color, not in mood.
A striking combination of vivid blues and purples, you can see our blue
parrotfish hanging out on the second level of the tank by the barrel coral and
the schooling grunts.

Parrotfish get their name from their large teeth that are fused together. The
upper teeth stick out and cover the lower, giving their mouths the appearance
of parrot beaks. Parrotfish use their teeth to bite off pieces of stony coral.
They grind the coral down to extract the soft coral polyps growing on the coral
surface. Inside the coral polyps are zooxanthellae, a single-celled algae that
provide the bulk of a parrotfish's nutrition. They also scrape algae off the
surface of the reef, providing a valuable service to the reef as too much algae
can smother the coral.

As unappetizing as chewing up coral may sound, since the coral in our Giant
Ocean Tank is made of fiberglass, we feed the parrotfish a mixture of plaster
of paris and algae, which gets squirted into its general region once a day.
Mmmm. It also eats zooplankton, lettuce and a nibble of fish. Because of their
coral crunching habit, parrotfish can produce as much as one ton of coral sand
per acre of reef each year. Their grinding is so loud that snorkelers can hear

A question we frequently get here at the New England Aquarium is, "Do fish
sleep?" The parrotfish is often an example in our answer because of their
unique solution to the sleeping issue. Each night, parrotfish take roughly 30
minutes to cover themselves in a clear mucus cocoon that allows them to spend
the night actually sleeping on the reef floor protected from predators. The
cocoon not only tastes bad, but also apparently prevents nighttime feeders like
moray eels from picking up their scent in the first place.

Another strange characteristic of parrotfish is their ability to change sexes.
While a parrotfish that is born male, dies male (called a primary male), a
female parrotfish may become a male (called a secondary male) when s/he gets
older. The evolutionary explanation for the sex change is that many of the fish
die young, so it's better for the survival of the species if there are lots of
females releasing eggs, since fewer males can fertilize lots of eggs.

Next time you're wandering up our helix ramp around the Giant Ocean Tank, be
sure to look for the blue parrotfish.
Droplet: Each fall and spring, the Aquarium's Fishes Department offers limited
space on week-long collecting trips during which we get animals like this blue
parrotfish to add to our collection. This September 26, we depart for Bimini!

----- MORE FISH, PLEASE: A MARINE MAMMAL TRAINER'S DAY ---------------------
By Mariette Vidal, Disco Insider

I arrive at the Discovery, the New England Aquarium's "floating pavilion" and
home to our sea lions and seals, at 9 a.m., as scheduled, to meet Jay Ferreri,
one of our marine mammal trainers.

We board the ship, go down some stairs and through a door, where there is a
plastic dish tub full of disinfectant for dipping our shoes. This keeps some of
the hitch-hiking germs away from our animals. Inside, I am immediately met with
the distinct smell of fish. Jay and the other trainers are busily stuffing
vitamins into thawed herring and capelin for the 7 harbor seals and 4
California sea lions in their care, and dividing them into buckets. Jay has
been here since 8 a.m., and his day operates in cycles. First he feeds the
seals, then the sea lions, then cleans their holding areas, then does a sea
lion presentation for Aquarium visitors, and then does it all again. The cycle
continues until about 6 p.m.

Jay and Jenny Montague, a trainer and assistant curator of marine mammals, are
used to visitors, and they take me and another intern off to feed the animals.
As we navigate the narrow hallways and passages of what is really a large boat,
Jay explains that all the animals are now molting and are not feeling their
best. Each summer, the seals and sea lions lose their old fur coats and grow
new ones. This process usually makes them lethargic and decreases their
appetites. Jay is particularly concerned about Amelia, a 15-year-old female
harbor seal, who is going through a particularly bad molt and did not have much
of an appetite the day before. Today she is fine. She munches down her fish,
gets her teeth brushed (with poultry-flavored toothpaste) and is extremely

Next stop: Chacoda and Reggae, two young (5 and 7, respectively) and sometimes
rambunctious males. Then, we stop in on Smoke, our oldest harbor seal (29) and
Reggae's and Amelia's mother. Smoke was found stranded on a beach in 1971, and
has been with us ever since. Harbor seals have a life expectancy of about 36
years, and Smoke is doing quite well despite having cataracts in both eyes,
which impair her vision. She navigates with the help of her sensitive whiskers.
Her partial blindness does make her particularly shy around strangers, like me.
Smoke gets fish and eyedrops, and then we head back to the kitchen.

Now the sea lions: Jay takes me to feed Guthrie, who is currently weighing in
at 831 pounds. As he jumps out of the pool and skids towards us on the slippery
floor, I am a bit startled by his size. Jay has Guthrie give me a big wet kiss,
and my fear subsides. We quickly run through a training session with Guthrie.
When he's molting, he can lose his motivation to perform. This morning he's not
showing much interest at all, and so will be relieved from performing by Zuma
and Tyler.

Before going back to my desk in the Communications Department, where I am a
summer intern, I watch Jenny do the first sea lion show of the morning. Jay is
cleaning the pens. Usually, only one sea lion performs, but with the "boys" out
of sorts from molting, the trainers have opted to have two animals do a show.
First Zuma comes out, but he is distracted and keeps diving into the water.
Tyler comes out next, and is particularly funny this morning. When he gives his
best sea lion roar, Jenny can't help laughing. The kids in the audience love
that. I watch quietly from the second row, pondering the glimpse I have had
into the lives of these marine mammal trainers. It's pretty hard work, but when
Tyler sticks out his tongue at all the non-recyclers in the audience, I have to
think it's also a lot of fun.
Droplet: Although they are not considered endangered, California sea lions
continue to be protected by the 1972 Marine Mammal Protection Act. Destruction
of their natural habitat and coastline development are threats to their
population. Growing populations of both humans and sea lions do have their
moments, however. One of the most infamous occurred at Pier 39 several years
ago in San Francisco, California. Pier 39, a popular shopping area at the
water's edge, attracted lots of sea lions. Space on Pier 39 quickly became a
commodity. Since sea lions are protected, the owners and managers of the
yachts and shops could do little to discourage the sea lions. Finally, since
the sea lions attracted so many tourists, city planners built another dock for
the yachts. Now that's working with nature!
