Whale shark occurs worldwide in the tropical Atlantic, Pacific, and Indian Oceans between about 30 degrees North and 35 degrees South. A loose grouping of fish is called a shoal. The biggest, or heaviest, fish is the ocean sunfish which can weigh as much as 5,000 pounds. While most sea anemones are relatively harmless to humans a few do contain strong toxic substances producing quite severe effects.

The rise in demand for shark products increases pressure on fisheries. [32] Major declines in shark stocks have been recorded—some species have been depleted by over 90% over the past 20–30 years with population declines of 70% not unusual. [108] A study by the International Union for Conservation of Nature suggests that one quarter of all known species of sharks and rays are threatened by extinction and 25 species were classified as critically endangered. [109] [110] Other threats include habitat alteration, damage and loss from coastal development, pollution and the impact of fisheries on the seabed and prey species. [111] The 2007 documentary, Sharkwater exposed how sharks are being hunted to extinction. [112] In 1991, South Africa was the first country in the world to declare Great White sharks a legally protected species. [113] Intending to ban the practice of shark finning while at sea, the United States Congress passed the Shark Finning Prohibition Act in 2000.
