HONOLULU (USA)- In february a basking shark, tagged off the coast of San Diego, California, checked in after eight months of silence near Hawaii. Scientists are excited about the proven direct connection between basking sharks in the eastern Pacific and the central Pacific.
The fish, tagged near San Diego, was one of only four basking sharks ever tagged in the eastern Pacific, and the lone shark to keep its tag for such a long time.
Basking sharks, the second-largest fish on the planet, were once plentiful along the Pacific coast of North America, gathering by the hundreds and even the thousands. Now, it’s a rare treat to see even one of these ocean giants.
Researchers at the National Oceanic and Atmospheric Administration’s Southwest Fisheries Science Center in La Jolla, California are very excited. They never expected the shark to travel this far into the ocean. The journey of roughly four
thousand kilometers from California to Hawaii is the farthest ever recorded for a basking shark in Pacific waters.
And in addition to revealing where the sharks may go when they leave coastal waters, the tracking device also revealed somewhat startling information about where the sharks like to hang out.
Near Hawaii, the colossal fish spent all its time in surprisingly deep seas, lingering in twilit waters 500 meters down during the day, and commuting up to a depth of 200 m at night.
Data on the record-breaking trek came just four days after one of the only other tagged sharks also pinged a satellite, this time about 800 km off the coast of Baja California, Mexico.
