Head buts, tail slapping or violent jaw snapping are behaviours observed in situations that are potentially dangerous for them. On the other hand, sperm whales have other means of reacting. As is typical in other deep-diving cetaceans, skull asymmetry in dwarf sperm whales ( Kogia sima) is also predictable, exemplified in this head-on view. Scenes were documented in the Galapagos Islands and some sperm whales show shark bites. Nevertheless, the latter react to killer whale and pilot whale attacks in the same manner.įalse killer whales and sharks can also prey on sperm whales. There is no evidence that pilot whales are a real threat to sperm whales. Pilot whales sometimes behave aggressively at these encounters and the “marguerite” formation was observed in sperm whales on a few occasions. Off the coast of Ecuador, interactions between pilot whales and sperm whales are frequent. This time, sperm whales were being attacked by pilot whales. Exclusive Economic Zone are divided into two discrete, non-contiguous areas: 1) waters off California, Oregon and Washington (this report), and 2. On the 31st of March 2016 a Dwarf Sperm Whale (Kogia sima) was reported live stranded in Jurien Bay to Paul Jennings, Jurien Marine Park Coordinator and Chris. For the Marine Mammal Protection Act (MMPA) stock assessment reports, dwarf sperm whales within the Pacific U.S. Hunting giant sperm whales is not easy due to their aquatic nature (and their sheer size). the distribution of dwarf sperm whales, or to delineate possible stock boundaries. The same situation was observed in the Gulf of Mexico. Giant sperm whales are the largest creatures in the game by a wide margin they are eight times the size of a dragon, ten times that of a bronze colossus, about 380 times the size of a fully-grown bull moose, and about 3,330 times the size of a measly dwarf. Despite these efforts, all the sperm whales were injured and one was killed. Whenever killer whales managed to oust one individual from the “marguerite”, one or two other sperm whales intervened and tried to escort it back into the formation. Males arrived toward the end for reinforcement. Female killer whales, some with young, organized the attack. ![]() Notably, one study describes how 35 killer whales attacked a group of nine sperm whales, 130 km off the coast of California. Various scientific publications have documented this defence technique. This same technique is also used by land mammals such as elephants. If there are any young or vulnerable individuals, they are positioned in the centre. The sperm whale has even developed a position to protect itself from attackers, the so-called “marguerite” formation: heads together and tails facing outwards. However, the sperm whale is a toothed whale that can grow up to 18 metres long and weigh 50 tonnes! Does an animal of this size have predators? The answer is yes. Toothed whales are generally much smaller than baleen whales.
