Comparison with Antarctic blue whales showed that this hybridization began after the separation of the northern and southern populations. Despite their smaller size, fin whales have similar cruising and sprinting speeds to blue whales, which would allow fin males to complete courtship chases with blue females. [24]
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. While this ocean mammoth is dubbed “blue,” its color is more a reflection of the water it swims ...
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 ...
Comparison of actual brain size with the size expected from allometry provides an encephalization quotient (EQ) that can be used as a more accurate indicator of an animal's intelligence. Brain of the sperm whale, considered the largest brain in the animal kingdom
In 2023, paleontologists estimated that the extinct whale Perucetus, discovered in Peru, may have outweighed the blue whale, with a mass of 85 to 340 t (94–375 short tons; 84–335 long tons). [18] However, more recent studies suggest this whale was much smaller than previous estimates putting its weight at 60 to 113 tonnes. [19]
Baleen whales range in size from the 6 m (20 ft) and 3,000 kg (6,600 lb) pygmy right whale to the 31 m (102 ft) and 190 t (210 short tons) blue whale, the largest known animal to have ever existed. [ 1 ] [ 2 ] They are sexually dimorphic .
