In this photo taken July 5, 2011, A marine biologist measures a dead hammerhead shark after it was caught by fishermen in Puerto Lopez, Ecuador. Thousands of young sharks in danger of extinction are regularly caught by fishing boats along the Ecuadorian coast to be sold mainly to Asian markets. A 2007 presidential decree authorized fishermen to sell shark meat and fins as long as the animals were caught by accident in fishing nets. (AP Photo/Patricio Realpe) less
