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.
Spindle cells (neurons without extensive branching) have been discovered in the brains of the humpback whale, fin whale, sperm whale, orca, [20] [21] bottlenose dolphins, Risso's dolphins, and beluga whales. [22] Humans, great apes, and elephants, species all well known for their high intelligence, are the only others known to have spindle cells.
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it inhabits a wide range of marine environments, from Arctic to Antarctic regions to tropical seas.
However, as Barbara and other scientists have documented, animals exhibit behaviors that align with grief in humans — altered routines, withdrawal, loss of appetite, and visible mourning rituals.
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
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 ...
Scientists saw a male orca kill a juvenile great white shark within minutes last year. The hunting behavior could be a sign of a wider shift in the marine ecosystem.
Orca vs. whale shark The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at ...
