In addition to primates and elephants, many other social mammals particularly have been observed engaging in tool use. A group of dolphins in Shark Bay uses sea sponges to protect their beaks while foraging. Sea otters will use rocks or other hard objects to dislodge food (such as abalone) and break open shellfish.
By using a "process of elimination" approach, researchers Krutzen et al. [61] reported evidence of culturally transmitted tool use in bottlenose dolphins (Tursiops sp.). It has been previously noted that tool use in foraging, called "sponging" exists in this species.
Although tool use was long assumed to be a uniquely human trait, there is now much evidence that many animals use tools, including mammals, birds, fish, cephalopods and insects. Discussions of tool use often involve a debate about what constitutes a "tool", and they often consider the relation of tool use to the animal's intelligence and brain ...
Atlantic bottlenose dolphins were featured in the first major dolphin attraction, named the Top Deck Show. Personnel used a form of shaping by requiring the dolphins to perform varying and increasingly higher jumps. Personnel would hold fish over the water and dolphins would leap into the air and take fish out of their hands or their mouth. [12]
A female bottlenose dolphin performing with her trainer. They are considered one of the most intelligent cetaceans. Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins.
Scientists trying to understand the hunting behaviors of bottlenose dolphins have come up with a unique solution: fit them with video cameras.
At least some wild bottlenose dolphins use tools. In Shark Bay, off Western Australia, dolphins place a marine sponge on their rostrum, presumably to protect it when searching for food on the sandy sea bottom. [79] This has only been observed in this bay (first in 1997), and is predominantly practiced by females.
Most toothed whales use clicks in a series, or click train, for echolocation, while the sperm whale may produce clicks individually. Toothed whale whistles do not appear to be used in echolocation. Different rates of click production in a click train give rise to the familiar barks, squeals and growls of the bottlenose dolphin. A click train ...
