World Whale Day is today. Celebrated on the third Sunday in February, the day was was started by a group in 1980 in Maui, Hawaii. They were concerned about the humpback whale, which is found in the waters off the island. Gregg Kauffman founded the Pacific Whale Foundation because he was concerned about the decline in whale populations. Whales are now protected by international laws. Prior to such laws whales were hunted. Even today bycatch and pollution threaten whale populations. Whales are the largest mammals. Two types of whale exist: baleen whales and toothed whales.
