People who want to watch marine mammals like dolphins often head to
theme parks such as SeaWorld. But after a killer whale at one SeaWorld
killed its trainer last month, critics are calling for a reevaluation
of keeping these huge animals captive. Ann Dornfeld has the story.

In the wild, a killer whale’s world sounds something like this:

But most people see killer whales in an environment like this:

[Electric guitar at SeaWorld show, chanting of “Shamu! Shamu!
Shamu!”, audience claps in time]

SeaWorld calls all of its performing whales “Shamu.” Millions of
people have visited SeaWorld over the decades to get splashed by
Shamu’s tail and watch trainers leap off the killer whales’ noses. The
trainers hug and kiss the animals between high-flying stunts.

But animal rights activist Will Anderson says there is nothing healthy
about the relationship between captive marine mammals and their
keepers. The waters around Seattle, where he lives, are home to wild
killer whales. Anderson has worked to free captive killer whales for
40 years.

“The relationships they have with their trainers are
nothing less than ‘Well, what else is there to do?’ If you’re starved
for what you innately need – social bonding – you’re gonna settle for
whatever morsel you can get.”

Killer whales are actually huge dolphins, not whales. Anderson says
tanks are no place for animals which roam up to 100 miles each day in
their native waters.

“Their bodies and their minds, and their behaviors,
their needs and their huge size, they are all adapted for the wild.
They are not adapted for tanks.”

At SeaWorld, Julie Scardina is the Animal Ambassador. She handles
public relations for the theme park. She says just because killer
whales can roam 100 miles a day in the wild doesn’t mean they often
do.

“The 100 mile statistic there is actually just a
capability. They have the capability of roaming that far, just like
humans have the capability of walking 20 miles or more per day. We
provide opportunities for exercise, for play, and of course during our
shows they get plenty of exercise.”

Scardina used to train killer whales. She says the tricks show the
public what the animals are capable of. And she says keeping killer
whales in a more naturalistic, aquarium-like environment wouldn’t
serve the animals well.

“I’ve worked with animals for over 30 years. There’s
no way you can convince me that it would be better to let an animal
kind of hang. That’s kind of like saying it’s okay to let a person sit
on the couch if they’d like. You need to provide stimulation, you want
to get them up and moving.”

Scardina says the goal of SeaWorld’s Shamu shows is to encourage
marine conservation.

“Well, certainly our mission is to educate people
about the oceans, to inspire them. And that’s what obviously our hope
is, is by seeing these animals and how incredible they are – I know
that’s how I became inspired when I was a child.”

But in a promotional video for SeaWorld’s main killer whale show,
called “Believe,” SeaWorld employees suggest a different theme… more
conquest than conservation.

“How do we get in the water with the top predator in the ocean, y’know. that kills and eats anything it wants at any time.
I thought for a moment right there, y’know what, this is really crazy
what we do. But we are doing it!”

The video, and the “Believe” show itself, focus on the power of the
human spirit – not the marine environment.

Activists like Will Anderson are calling for theme parks like SeaWorld
to return killer whales to their native waters, protected by huge
enclosures. There is general agreement that captive killer whales
wouldn’t survive if released into the open ocean.

Insights on Human Disease From Dolphins

New research on diseases in dolphins could help us understand more about cancer in humans. Samara Freemark reports:

New research on diseases in dolphins could help us understand more about cancer in humans. Samara Freemark reports:

Cervical cancer can be caused by human papilloma virus, or HPV.

There are a lot of different strains of HPV. And the more strains a person gets at one time, the higher the chance of developing cancer.

Other animals get papilloma too. But up until now, researchers thought only humans could host multiple strains at once.

Hendrik Nollen studies marine animal diseases at the University of Florida.

His team has now found multiple papilloma strains in the dolphins they’ve been studying, but they also found one very important difference between dolphins and people.

“There are no reports of cervical cancer in dolphins. So here we have an
opportunity to look at the same setting, the same situation, and see why does one species develop disease and another one doesn’t.”

Understanding why dolphins don’t get cervical cancer could mean a step towards a cure for humans.

NOAA Looks Into Navy Sonar

A new federal ruling could
protect marine animals by
changing how and where
the Navy uses sonar. Samara Freemark reports:

Critics of sonar say it’s so loud that it confuses whales and other marine animals, and can cause them to be injured or even die. That’s why environmental groups have been pushing for tighter regulations on the technology.

This week the National Oceanic and Atmospheric Administration, or NOAA, took a step in that direction. The agency acknowledged that current policies are not doing enough to protect marine mammals. And NOAA says it will identify critical marine habitats impacted by sonar.

Michael Jasny is a policy analyst with the environmental group the Natural Resources Defense Council. He hopes the policy will be a first step to banning sonar in those habitats.

“It’s not a prescription, it’s a plan. And it sets in motion potentially a very significant change. I mean, the proof will be in the pudding, of course.”

Jasny says his organization will work with NOAA and the Navy to negotiate sonar policy so that marine mammals are not hurt.

Television dolphins like Flipper
and the performing dolphins at
Sea World can trick people into
thinking it’s okay to feed and
swim with wild dolphins. But
Rebecca Williams reports dolphin
researchers say our behavior can
hurt and even kill dolphins:

(sound of a shorebird crying out)

Fort Myers beach is packed with tourists. I meet a guy named Justin who’s here in Florida from Cleveland. He’s already gotten close to wild dolphins.

“We were out here swimming and dolphins got within a foot of us. It was amazing. I’ve never seen that.”

In this case, he wasn’t doing anything wrong – because the dolphins came up to him. But swimming with wild dolphins can actually be considered harassment if you approach them or touch them.

That’s bad for the dolphins because it can change their behavior. It can disturb their feeding and resting behavior. And it can separate dolphins from their babies.

So it’s illegal to swim with or harass dolphins. You can get fined and even end up with some jail time. And that’s just the beginning of the dolphins’ problems.

Dolphin encounters are getting more common in Florida and Hawaii and a lot of other places. There’ve been more tourists and more boaters in the water… and more commercial operations that promise you’ll get a chance to feed or swim with dolphins.

As cool as it might be for us, it’s actually terrible for dolphins. When people feed them they can get addicted to human handouts.

Cartoon Dolphin PSA: “For me it started with one hit of sardines, oh sardines… that’s where I learned to beg. It was easy to score free fish… with this dolphin smile? Yeah it’s illegal but no one cares…”

That’s a cartoon dolphin in rehab with a bear, a raccoon and a seagull. All those other animals we’ve gotten into some bad habits with.

It’s a message put out by the Mote Marine Laboratory in Sarasota.

(sound of dolphin playing in tank at the Marine Lab)

Randall Wells is the head of dolphin research at the lab. He’s spent almost four decades studying dolphins.

He says, in recent years, there’s been a dramatic increase in the number of dolphins getting into trouble with people. More people feeding them and getting too close to dolphins in their boats.

“And we’ve seen an increase in mortality from these kinds of interactions – from people luring animals in towards boats, in towards fishing gear. Dolphins have begun to take bait from lines getting tackle including hooks and lures in their bodies and killing them or seriously injuring them.”

He says, if you feed a dolphin, it’ll often start begging for food from people. And that dolphin will teach its babies or other dolphins to beg.

Sometimes they’ll even eat things that aren’t food. One dead dolphin had a plastic snake in its stomach.

If dolphins get closer to boats, they can get snared in fishing line. It can slice through their flippers. Once, Randall Wells rescued a dolphin that had a Speedo on its head. And because it couldn’t shake it off, the suit was cutting into the dolphin’s flesh.

Wells and his team have been doing a lot of outreach to stop people from getting too close to dolphins. And he says most of the time, it works.

“But there’s still a half percent of people that, by their own admission, insist on interacting with these animals – feeding them and approaching them in ways that are illegal, just because they can and they’ve never seen the negative consequences of doing that.”

If you want to go on one of those dolphin viewing tours, there are some ways to make sure the tour operator’s not adding to the problem.

Stacey Horstman helps run a program called Dolphin Smart. It certifies dolphin tours as responsible.

Right now there are only four businesses in Key West and one in Alabama that’ve gotten certified. But, she says, if you’re in a place without Dolphin Smart tours, you can still ask questions.

“Just to make sure that feeding is not being promoted in any way, that they’re promoting responsible viewing from a distance.”

That means staying at least 50 yards away from dolphins.

She says any ad that shows people swimming with dolphins or handing them fish is usually a sign of an irresponsible business. So those are ones to stay away from.

Dolphins might look cute and friendly, but Horstman says they are wild animals and they need their space.

The Case of the Disappearing Dolphin

  • A false killer whale, which is actually a type of tropical dolphin, with calf (Photo by Deron Verbeck, courtesy of iamaquatic.com)

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Transcript

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Jim Cook has been a fisherman in Hawaii for 18 years.

“You know, it used to be real simple: catch a fish, sell it, and go
back out and try and catch another one.”

Now he owns a company that operates six fishing vessels. Cook’s
ships catch deep swimming sashimi-grade tuna that ends up in sushi
restaurants across the US. They use a technique called longline fishing.

“We have around 45 miles of mainline to which we attach floaters
and 2200 to 2500 baited hooks.”

“The regulations imposed on the Hawaii longline fishery are
probably the most restrictive regulations on any longline fishery in the
world.”

That’s Bill Robinson. He’s an administrator with the National
Marine Fisheries Service. And these regulations he’s talking about are
meant to reduce bycatch. That means catching marine animals other than
the tuna. As a result of these policies, sea turtle bycatch has dropped
by more than 90-percent and seabird bycatch by 95-percent.

Things are looking up, but now there’s another problem. The numbers of
another kind of animal – the false killer whale – are declining. No one
knows why they’re disappearing. It might be related to longline
fishing, but it’s just not clear.

Robin Baird’s a biologist with Cascadia Research.

“There’s a whole variety of lines of evidence that imply the false
killer whale population around the main Hawaiian islands has declined
dramatically over the last 20 years. And I think it’s clearly the most
serious conservation or management issue for whales and dolphins in
Hawaiian waters today.”

Baird thinks the decline is partly related to fewer numbers of tuna
and other species false killer whales eat. He also suspects that the
false killer whales might be moving farther offshore, where they could
get hooked when trying to eat the tuna caught by the longline fishery.

So the question is: should the National Marine Fisheries Service come up
with even more regulations for the longline fishery in case more false
killer whales move offshore looking for tuna.

Bill Robinson with the Fisheries Service isn’t so sure that they
actually go that far offshore.

“That’s speculation, and it may or may not be true. What we
don’t really know is what the range of each population is.”

So, really, at this point, it’s anyone’s guess why the false killer whale numbers are declining.

The biologist, Robin Baird, is concerned that nothing’s being done.

“Unless something is done to change the factors that are
influencing the population, it probably will continue to decline.”

The environmental group Earthjustice and a coalition of
conservation groups have sued the National Marine Fisheries Service over
failing to develop a plan to protect the false killer whales.

The agency has not responded officially to the lawsuit yet. But Bill
Robinson says an action plan is in the works.

“Hopefully by the fall, we’ll be able to not only appoint the
team, but have the team begin work on a take recovery plan that will
make recommendations to the agency to reduce the incidental take of
false killer whales in the fishery.”

Such a plan might end up costing the commercial fishers money. But
Jim Cook says he’s willing to pay. That’s because false killer whales
pick fish off his lines. They eat the caught tuna before the fishers
can haul them in. That can mean a lot of lost income.

“We would very much welcome any methodology almost
irrespective of cost because we’re suffering quite a bit economically as
it is.”

But the National Marine Fisheries Service first has to find that
methodology.
