first Fraser's dolphin found
in the country dies Specialists from the National System of Conservation Areas, SINAC, announced on Tuesday the death of Fraser's dolphin (Lagenodelphis hosei) that had run aground on the coast of Barra de Tortuguero in Pococí Canton, Limón Province. According to the SINAC's report, this is the first time that the arrival of Fraser's dolphins in the country has been recorded. The mammal had been found on Friday, still alive. He had run aground on a sandbar on the coast of Barra de Tortuguero. The animal was found by people who were near the Tortuguero National Park, who later reported the incident to the park rangers. Then, "the Tortuguero National Park rangers with the support of police officers, members of the Sea Turtle Conservancy, a marine biologist from the LAST organization, employees of the Hotel Turtle Beach Lodge and volunteers, attended to the animal to give it support while it was dying," SINAC said in its statement. Unfortunately, the dolphin died for reasons that are still unknown, but it's stranding could have been caused by its physical state, age or climatic factors, variations in terrestrial geomagnetism and oceanographic conditions. According to SINAC, other causes that may have caused this unusual arrival of the dolphin are the impact generated by human activities such as contamination and interaction with fishing activities. A dolphin or whale "could get caught in nets or hit by boats." The case was attended by the veterinarian Gabriela Hernandez - Mora, of the Bacteriology Laboratory of the National Animal Health Service, who will be in charge of finding the cause of the death of the Fraser's Dolphin. According to specialists, Fraser's dolphin, also called Sarawak dolphin (Lagenodelphis hosei), has been recorded with an average size between 2.5 or 2.7 meters long, a weight between 160 and 210 kilograms. The upper part of the back (including the fin dorsal) is dark gray. His face has a dark stripe resembling that of raccoons. It has between 40 to 44 teeth, its body is robust and with a small snout. Their fins are all triangular and pointed, the dorsal fin that is located in the middle of the upper body is small. It feeds on fish, squid and crustaceans. They have been recorded mainly in the Pacific Ocean. ------------------------- What could the authorities do to prevent marine animals from continuing to run aground on the coasts?
