Tagging of Pacific Predators (TOPP) began in 2000 as one of many projects formed by Census of Marine Life, an organization whose goal is to help understand and explain the diversity and abundances of the ocean in the past, present, and future. After they were formed, TOPP began by building a coalition of researchers from all over the world to find and study predators of the Pacific Ocean. Since then, they have satellite-tagged 22 different species and more than 2,000 animals. These animals include elephant seals, great white sharks, leatherback turtles, squid, albatrosses, and more.
