Marine scientist, Dr. Demian Chapman, discusses how the illegal shark fin trade is harming sharks and the health of the oceans. He shares his experiences tagging sharks to track the animals’ long journeys and explains why sharks don’t deserve their fearsome reputation.
“Waimanu – a Hawaiian Monk seal – was seen at the Manta Ray Night Dive a few times over the past few weeks, but always on the dark outskirts. Last weekend, we captured NEVER-BEFORE-SEEN footage of Waimanu swimming through the dive site while the Manta Rays were feeding on plankton.
The Hawaiian Monk seal is considered a critically endangered animal with a population of approximately 1100. Most Hawaiian Monk Seals live around the Northwestern Hawaiian Islands; only a few populate the main Hawaiian Islands. Three monk seals inhabit the Big Island and Waimanu – the only female – is currently pregnant.”

There’s World Turtle Day (May 23) then there’s World SEA Turtle Day, which is today! Why is June 16th World Sea Turtle Day? It is the birthday of Dr. Archie Carr who is widely known as “the father of sea turtle biology.” Dr. Carr focused his entire career on sea turtle research and conservation. According to The Sea Turtle Conservancy:
Archie Carr was a great biologist. His early descriptive studies of turtles set the standard of quality in the field of natural history. Later on, as he focused on sea turtles, he moved toward ecology and behavior, although his work always retained a taxonomic and evolutionary perspective. For decades the National Science Foundation (and the Sea Turtle Conservancy and the Office of Naval Research) supported his research at Tortuguero, enabling him to mount one of the longest lasting and most intensive studies of an animal population that has ever been done. To date, more than 35,000 adult female green turtles have been tagged at the research station at Tortuguero. From this effort have come papers by Archie Carr, his students, and other investigators on orientation, migration, nesting behavior, nest physiology, sensory physiology, nutrition, demography, and other subjects. Almost all of the studies have significance for conservation — Archie Carr was a conservation biologist long before the field was recognized.
Of the seven sea turtle species, five are listed on the IUCN Red List as either vulnerable, endangered, or cirtically endangered. They are: leatherbacks (vulnerable), loggerheads (endangered), hawksbills (critically endangered), green sea turtles (endangered), Kemp’s Ridley (critically endangered), Olive Ridley (vulnerable), and flatback sea turtles (data deficient). What can you do to protect sea turtles?
- At night, keep bright lights off the beach to encourage sea turtles to nest and to ensure hatchlings can find their way to the sea.
- Keep beaches trash free to avoid turtles mistaking it for food or getting caught in plastic loops. Single use plastic bags are often mistaken by sea turtles for their favorite food, jellyfish. Consumption can cause them to suffocate.
- Join a coastal conservation effort working to protect sea turtle nests from predators.
- Of course you can always donate to MarineBio or join the MarineBio Conservation Society to help us share species information and raise awareness about the plight of endangered sea turtles. Whether you can spare $5 or $50, it will help us continue bringing the world a vast source of information on all things ocean.
The appearance of the world’s rarest whales has been recorded for the first time after a mother and her calf washed up on beach in New Zealand in 2010. Spade-toothed beaked whales (Mesoplodon traversii [IUCN]), aka Bahamondi’s or Traver’s beaked whales, are so rare that they have yet to be seen alive and only recently have scientists confirmed that a five-meter specimen found alongside its male offspring two years ago belonged to the rarest species of whales.

The following outstanding 2 hour video shows the amazing biodiversity of the marine life in the Andaman Sea (in the northeast Indian Ocean). Produced by Nick Hope at Bubble Vision, he again amazes us while introducing us to many rarely seen marine species the way they should be met, in their home under the sea.
Sea turtles have been making it to the top of the headlines recently, all positive for a change and I thought I would use this blog to draw attention to this. Additionally, I feel it’s always nice to give some attention to the turtles.
So the first piece of news, the secrets of the sea turtle migration have been uncovered. It turns out that the reproduction migration (females returning to their nesting beaches) is not the longest migration that sea turtles carry out. It has been found from the compilation of long term capture programs that the migration of immature turtles, termed “developmental migration”, is longer than the reproductive migration. Also this migration is only carried out once in their life time rather than every few years. On the migration topic as well, a study was carried out to determine the migration of juvenile leatherback sea turtles. However, due to the size and the weight of the juveniles it is impossible to attach a satellite tag to their shells without them sinking. So instead of following the hatchlings the scientists followed the currents. The “lost years” of a turtle’s life, the age between hatching and returning to foraging grounds can be anywhere between 3 to 5 years after they hatch. These years are the least understood part of a turtle’s life. Knowing more about where the turtles swim before they reach adulthood could be critical in protecting the species. Continue reading
Today I’m going to take you on a voyage to some place so deep, so dark, so unexplored that we know less about it than we know about the dark side of the moon. It’s a place of myth and legend. It’s a place marked on ancient maps as “here be monsters.” It is a place where each new voyage of exploration brings back new discoveries of creatures so wondrous and strange that our forefathers would have considered them monstrous indeed. Instead, they just make me green with envy that my colleague from IUCN was able to go on this journey to the south of Madagascar seamounts to actually take photographs and to see these wondrous creatures of the deep.

International coalition advances marine conservation as part of the solution to climate change
WASHINGTON, Nov. 18 /PRNewswire-USNewswire/ — A large international coalition today urged the United States to support marine conservation options that will help mitigate climate change.
The ‘Blue Climate Coalition,’ comprised of sixty-six conservation groups and interests and over 150 marine scientists and professionals, from 33 countries, issued communications today addressed to President Obama and the United States Senate.
Together, the coalition letters request the option for marine conservation solutions to climate change to be considered in national climate change legislation and international climate change treaties, and support for marine science research that further explores this concept. Continue reading
WDCS Press Communication
A worldwide web for whales: The special places where whales and dolphins live and the people who know them.
Maui, Hawaii, 3rd April 2009: On the final day of the first International Conference on Marine Mammal Protected Areas, experts addressed future challenges for the management of existing and the establishment of new marine protected area networks. The more than 200 marine mammal scientists, MPA managers and other experts from 40 countries agreed that this gathering on the shores of the Hawaiian Islands Humpback Whale National Marine Sanctuary was a valuable experience that needs to carry on by building an enduring network.
While humpback whales, often in sight of conference delegates, cavorted offshore on their mating grounds, a key recommendation from the conference came out of a workshop convened by WDCS Research Fellow Erich Hoyt:
“A worldwide effort must be made urgently to identify and define whale and dolphin critical habitats and hot spots,” said Hoyt. “Then we need to map this information with other species and ecogeographic data to create MPA networks in national waters and on the high seas. It is like creating a sort of worldwide web for whales and dolphins but connecting not just the animals, but the special places where they live, and the people there too.”
Conference delegates will bring these and other recommendations to the upcoming meeting of the International Marine Protected Areas Congress (IMPAC 2) in Washington DC, in late May, and they will also form part of the work plan for the IUCN WCPA High Seas MPA Task Force.
“Probably less than 1 percent of the world’s marine mammal critical habitat has been identified much less protected,” added Hoyt. “We have discussed strategies for cost-effective measures to attack this huge workload with surveys and other studies. Clearly the emphasis will need to be on rare and endangered species, but we also need to protect healthy populations so that they don’t join the endangered ranks.”
In his conference keynote, Hoyt praised the fine recent record in the high level protection in the Pacific where 10 of the world’s largest 15 MPAs are located, including the Great Barrier Reef Marine Park in Australia and the Papahanaumokuakea Marine National Monument, in the Hawaiian Islands, at 362,000 sq km, the largest highly protected area in the world. But he reported that approximately 40% of the 300 existing marine mammal MPAs are clearly too small and even a higher percentage offer no real protection. MPAs in Europe, East Asia, West Africa and the Middle East were particularly small and ineffective even for protecting coastal dolphin habitat, much less that of large whale species.
“Networks will solve some of the problems of individual small size if we are clever about what we protect, but much better zoned and well-managed protection is clearly needed.”
WDCS is a sponsor of the International Conference on Marine Mammal Protected Areas. WDCS was represented with five experts, two of them Members of the Steering committee and Erich Hoyt as co-chair of the programme committee. Presentations and posters included the announcement of the South American River Dolphin Protected Area Network (SARDPAN), cetacean habitat surveys of the Pacific Islands region and Patagonia, Argentina, an introduction to the proposed MPA in the Ross Sea, Antarctica, and the Adelaide Dolphin Sanctuary, in Australia.
