Orcas hearts are 9.5 meters, Humpback Whales hearts are 14.5 meters, and Sperm Whales hearts are 18.5 meters long. The population of the whales is a few thousand which varies on the reproduction and species. There are many threats that whales face such as whaling, entanglement in fishing gear, climate change, ship strikes, oil development, habitat degradation, and unauthorised capturing. A whale’s large size is its best protection from predators and the formation of pods (social groups) also helps protect the more vulnerable members. When full grown, the largest whales have no predators except man, parasites, and disease. The different whales sometimes have different kinds of prey. The Sperm Whale eats squid, the Stejneger's Whale eats squid and salmon, the Baird’s Beaked Whale eats Gadiform fish, Squid, and crustaceans, Orcas eat Seals, Sea lions, Penguins, Sharks, Cetaceans (Whales, Dolphins, and Porpoises) not people, the Blue Whale eats Crustaceans (krill). Killer Whales attack and attempt to kill Grey whales sometimes with victory. Southwest Fisheries Science Center says that killer whales may be responsible for the mortalities consulting up to 35% of the average annual calf production of California Grey Whales.” Orcas predators are Humans, disease, and parasites and Beluga whales predators are killer whales and polar
