![]() Furthermore, climate change and the increased presence of humans in bodies of water around the world pose threats to all cetaceans. Dolphins and porpoises are severely threatened by incidental entanglement in gillnets, which accounts for a vast majority of human-caused dolphin and porpoise deaths. While this group of cetaceans was not heavily targeted by whalers, many species still face threats of extinction. The second group of cetaceans, the Odontoceti or toothed whales, includes dolphins, porpoises, and whales like sperm whales, all of which possess teeth. Although commercial whaling was banned in 1986 by the International Whaling Commission (IWC), some species like the sei whale are still heavily targeted by Japan, Norway, and Iceland, which dodge or defy the IWC moratorium. Centuries of intensive hunting left most baleen species in shambles, and since they reproduce slowly, scientists worry that they're now more vulnerable to threats like pollution and ship strikes that might have otherwise been minor. The diets of baleen whales allow them to accumulate large quantities of blubber, which made them favorite targets of 18th- and 19th-century whalers seeking to boil down blubber into valuable whale oil. Members of the first group, the Mysticeti or baleen whales, are filter feeders characterized by their baleen plates, which they use to filter plankton and other small organisms out of the water. Cetaceans are divided into two distinct groups, with members of each group facing unique threats to their survival.
