Boat filled with protected species hits coral reef

Well it happened again, but this time it’s even worse. A Chinese vessel ran into a protected coral reef in the Tubbataha National Marine Park in the southwestern Philippines last week (Tubbataha is the same place where the U.S. Navy ship also ran aground). In addition to the damage the ship caused to the reef, officials found more than 22,000 pounds (10,000 kg) of meat from the protected pangolin or scaly anteater on board. The 12 crewmen face poaching charges and will also likely be charged with damaging the reef and violating the country’s wildlife law.

UPDATE Apr 21 —
The Chinese Poachers’ ship was removed from the reef on Friday after it was deemed safe to tow. The crewmen pleaded not guilty to the poaching charge but they have also been charged with corruption for trying to bribe their way out…

Dancing squid

Near the Lofoten archipelago in northern Norway, a team of researchers captured amazing footage of a little squid, Gonatus fabricii. This squid can grow up to 35 cm and is an important food source for whales, seals, fish and seabirds in the Barents and Norwegian Seas. Watch the following video to see it’s cool, translucent wings as it swims in front of the camera.

Sharks dive deep on moonlit nights

New research reveals that water temperature, time of day and the Moon affect the diving behavior of grey reef sharks. The sharks were tagged near Palau and tracked for two years during which the researchers recorded information about their dives. They were found to dive to an average depth of 60 meters in summer because the water was warmer and only 35 meters in winter because they had to stay closer to the surface where the water was warm enough. They also dove deeper in the morning than in the evening and the sharks stayed in deep waters longer on nights with a Full moon.

West Coast Fishery Managers Approve Fisheries Sea Change

Last week, fishery managers approved the first Fishery Ecosystem Plan that will help protect currently unmanaged forage fish in the western Pacific Ocean. An ecosystem approach is ideal because instead of focusing on just one fish stock, it will include how everything is connected.
