By Miguel Llanos, msnbc.com   Thousands of leatherback sea turtle hatchlings and eggs were crushed over the weekend by bulldozers and excavators used to divert a river on the Caribbean island of Trinidad. “Unfortunately the engineers in charge bulldozed a far greater portion of beach than necessary, and they did destroy many viable nests,” the Papa Bois Conservation group posted on its Facebook page. It wasn’t immediately clear how much of an impact the tragedy would have on the critically endangered species, but the group noted that it happened on “the world’s most densely populated leatherback nesting beach.” Papa Bois said it wasn’t opposed to diverting the river, since it had been eroding not only a local eco-tourist hotel but the nesting area itself. But it noted that the work was done without supervision by “any of the … Read entire article »

My Shark Brief – Cay Sal Banks Bahamas

It has been a few years since I’ve visited Cay Sal Banks, Bahamas. Since Nekton closed it doors, finding a suitable organization that can provide the accommodations and amenities to live comfortably for a week is difficult. I have visited Cay Sal Banks three times.

The last time I visited Cal Sal, 2009 I brought my HD UW Video rig along to film the sharks. The first two visits, the variety and abundance of sharks was impressive. To be in the water with sharks swimming all around you, some skimming over your head by … Read entire article »
