06.12.01 - TRAGIC END TO C-6 SAGA
Dolphin C-6 ("Philippe") was found dead Tuesday, June 12, in the Sebastian River about 40 miles
north of HARBOR BRANCH. "Philippe" apparently died of natural causes. A preliminary examination
found the remains of a large fish stuck in the dolphin's airway and it appears he died of
asphyxiation.
Steve McCulloch, Director of Dolphin Research, said "We're saddened and disappointed and feel
that we've lost not only a valuable animal but one that was also a friend. However, Philippe
provided invaluable data to us while in captivity and even in death will be able to teach us
more about how he and other dolphins lived."
04.04.01 - C-6 (PHILIPPE) IS HOME AND DOING WELL
Based on recent observations by the Dolphin Research Team we have learned that C-6's
(Phillipe) body condition is good and his respiration rates and behavior are normal. Over
the past month since his post-rehabilitation release from HBOI, C-6 has been seen many times
as he continues to avoid boat traffic and human interaction. He has been foraging for himself,
he is interacting with groups of dolphin, and seems to have adapted socially. He has also
reunited with lifelong partner, C-7, who was thought to have been with C-6 in August, 2000,
during the shark attack. It was not known if C-7 had survived the shark attack, but C-7 has
been sighted in the Indian River Lagoon with C-6 once again
(see video below). The VHF tag worn by C-6 (which has a 30 mile range
in calm weather) continues to perform flawlessly. Until the tag falls off, the Dolphin Research
Team hopes to get 3 - 4 visual sightings, and several terrestrial sightings each day to plot
his location.

03.05.01 - C-6 (PHILIPPE) RELEASE IS JUST THE BEGINNING OF FURTHER STUDY, MANAGEMENT EFFORTS
Dolphin C-6 ("Philippe") has been released into east-central Florida's Indian River Lagoon - free to once again join the other dolphins living there. The release marks the end of one
of the most successful marine mammal rehabilitation efforts ever attempted. But the release
also signifies the beginning of a new chapter in wild dolphin research that will help HARBOR
BRANCH scientists better understand how these magnificent animals live and thrive within their
natural environment.
Dolphin C-6 is a male Atlantic bottlenose dolphin (Tursiops truncatus) rescued by personnel
from various Florida State agencies and scientists from HARBOR BRANCH Oceanographic Institution
(HBOI) last August, after barely surviving a brutal attack by bull sharks in the Indian River
Lagoon. In October, C-6 was renamed "Phillipe".
Dolphin C-6 has been fitted with a two-ounce, state-of-the art VHF transmitter that will enable
the researchers in HBOI's Division of Marine Mammal Research and Conservation (DMMRC) to track
his movements for the next 60 to 90 days. Scientists attached the transmitter to the trailing
edge of the dorsal fin prior to release. The transmitter was attached using a small plastic
pin and a simple surgical procedure similar to an ear piercing in humans.
The transmitter can send its signal up to 30 miles under ideal conditions. Dolphin Research
Division Director Stephen McCulloch said the data received will provide valuable insight into
how dolphins survive and how better to protect their environment. "This gives us a chance to
learn more about their social structures, habitat utilization, and what's referred to as their
'grand-scale movement patterns,' and their ability to re-adapt to the wild after an experience
like the one Phillipe has had. It also gives us more of a management tool for our ongoing
efforts to learn how we can be better stewards of the environment and the animals that live
there," McCulloch said.
Over the past six months, Philippe has gained a total of 130 pounds, increasing from an
immediate post-attack weight of 405 pounds to a release weight of 535 pounds. By the time
he was released, Philippe was eating between 18 and 20 pounds of live, fresh fish daily,
supplemented with vitamins. During his last three months of captivity, he was taken
completely off of antibiotics and in the past few weeks, human activity was reduced to an
absolute minimum to prepare Philippe for return to the wild.
The last medical check on Philippe was performed the morning of Friday, March 2nd. Blood and
tissue samples were all normal, and the dolphin's heart and lungs were also monitored and
deemed normal. The release plan was reviewed by a panel of marine mammal experts and approved
by the National Marine Fisheries Service.
HBOI researchers will attempt to make visual sightings of Philippe at least twice a week for
as long as they continue to receive signals from the attached transmitter.
Examinations of the teeth show put Philippe's age at 24 years. In the wild, bottlenose
dolphins may live to between 30 and 35 years of age. But scientists caution that Philippe's
future is uncertain. As long as Philippe is alive and resident within the Indian River
Lagoon, however, he and the other dolphins that make the estuary their home will continue to
provide valuable insights into the world they - and we - live in.
