MIAMI, June 15, 2016 /PRNewswire/ — The most ‘fintastic’ time of the year is back and making a huge splash! LA SEMANA DEL TIBURÓN (#semanadeltiburon) returns in its 28th anniversary and will keep viewers on the edge of their seat with all-new jaw-dropping and compelling stories about everyone’s favorite marine predator. Featuring new research from Mexico, Florida and Costa Rica, LA SEMANA DEL TIBURÓN will begin on Sunday, June 26 at 7PM E/4PM P and air through Saturday, July 2.

Here are some of the specials included in this year’s LA SEMANA DEL TIBURÓN:

TIBURÓN DE LA SELVA (Jungle Shark): Marine biologist Dr. Graig O’Connell and cameraman Andy Casagrande travel to the Sirena River in the jungles of Costa Rica to investigate reports of bull sharks and see how these unusual predators coexist with the enormous crocodiles that call the jungle river home.

As previously reported by The Costa Rica Star, bull sharks swim in shallow, brackish waters. They are known as “tiburón barrosa” (mud sharks) because they enjoy cooling off in muddy, brackish and shallow waters near the coast. Bull sharks can survive in freshwater environments, and they are true “river sharks” as they have been known to swim all the way to the Great Lake of Nicaragua – if they can make it past the crocodiles and caimans.

In 2009, conservationists and biologists of PRETOMA, a non-profit organization dedicated to the research and protection of marine resources in Costa Rica, made an interesting discovery in the Rio Sirena rivermouth, located in the Corcovado National Park: The juvenile bull sharks they tracked were getting bigger than expected.

PRETOMA researchers expected young bull sharks measuring three meters in length. They were surprised when the steel traps they set up were destroyed by four-meter long sharks. The researchers were then forced to pursue female baby bull sharks measuring one meter in length.

More programming featuring “el clásico de Discovery”:
EL GRAN MAKO (Monster Mako): Along the Gulf of Mexico a series of large Mako sharks have been spotted, one in particular said to be more than 15 feet long. A group of marine biologists travel to the area to reveal the mysteries of their unseen world, but they are so fast that just spotting one is almost an impossible feat.

TIBURONES EN LA COSTA (Shark Trek): Greg Skomal and the SharkCam team head to Florida, the shark attack capitol of the world, to investigate the invasion of massive sharks along the state’s coastline.

LA ISLA DEL GRAN TIBURÓN BLANCO (Island of the Mega Shark): The quest to photograph the largest great white shark continues as experts Andy Casagrande and Jeff Kurr join forces with Dickie Chivell at Guadalupe Island, Mexico. Theories suggest these mega sharks may come to feed and mate at this great white hot spot.
