A shark mauled a teenager in Russia's Far East making it the second shark attack near the Russian shores of the Sea of Japan in 24 hours, a spokesman for the local emergencies ministry's department said on Thursday. "We confirm another shark attack on Thursday near Zheltukhin Island. The victim was a young man born in 1995 and we are currently establishing the scale of injuries he suffered," the spokesman said adding that the teenager has been hospitalized in Vladivostok. A spokesman for the Khasansky rescuers department said earlier that the teenager suffered injuries to his legs. On Wednesday afternoon, a 25-year-old man lost both hands during a shark attack in Telyakovsky Bay near the village of Vityaz in the Far Eastern Primorye Territory. He underwent surgery and is currently in intensive care. Doctors say he is in stable condition. An ichthyologist from the Institute of Marine Biology in the Far East said on Wednesday the first shark attack was most likely related to feeding grounds as anchovies move towards shallower waters to warm themselves, though this usually occurs at the beginning of summer. The only shark species native to the territory is dogfish shark, which have never been recorded to attack humans. However, several white sharks, which can be dangerous to humans, have been detected in the area in the past few years, including a two-meter white shark caught in 2007.
