There are anecdotal reports that, c. 1955, an Inuk man fell prey to an orca entrapped by ice in Grand Suttie Bay (Foxe Basin, Canada).A pod of orcas (likely 10-12 animals) was trapped in a polynya, and a young man visited the site in spite of advice from elders to wait until the ice was strong enough.
Short film My Pilot, Whale (28’, 2014, directed by Alexander and Nicole Gratovsky [68]) demonstrates the possibility of interaction between humans and free-living pilot whales, offering the viewer a number of philosophical questions related to cetaceans: about their attitude to the world, what we have in common, what we — humans — can ...
A hunt begins with a chase followed by a violent attack on the exhausted prey. Large whales often show signs of orca attack via tooth rake marks. [84] Pods of female sperm whales sometimes protect themselves by forming a protective circle around their calves with their flukes facing outwards, using them to repel the attackers. [90]
Some whales, such as the sperm or Cuvier's beaked, can spend over an hour between breaths, the Whale and Dolphin Conservation reports. It may not look like it, but whales have hair .
The whales make groans, pops and belches typically at frequencies around 500 Hz. The purpose of the sounds is not known but may be a form of communication between whales within the same group. Northern right whales responded to sounds similar to police sirens—sounds of much higher frequency than their own. On hearing the sounds, they moved ...
A 2012 analysis of the scarification of right whales over the years 1980 to 2009 showed that 82.9% of all North Atlantic right whales experienced at least one fishing gear entanglement, 59.0% have had more than one such experience, and an average of 15.5% of the population are entangled in fishing gear annually.
The false killer is one of three toothed whales, the other two being the pilot whales, identified as having a sizable lifespan after menopause, which occurs at age 45 to 55. [19] As a toothed whale, a false killer can echolocate using its melon organ in the forehead to create sound, which it uses to navigate and find prey.
Fin whales, humpback whales and sperm whales have been found to have spindle neurons, whose function is not well understood, which is a type of brain cell known to exist only in certain other species of high intelligence: humans, other great apes, bottlenose dolphins and elephants.
