Although the blue whale’s brain is large when compared to human’s, it is relatively small regarding its body size. Blue whale’s brain has a weight of about 7 kg (6.92 kg) / 15.3lb, which corresponds with only 0.001-0.007% of its total body weight. The blue whale’s tongue reaches...
000 cm³, the sperm whale’s brain is the largest of any known modern or extinct animal. Its size is more than three times that of an average adult human brain in volume. Despite its massive size, the sperm whale’s encephalization quotient (EQ) is relatively low, at around 0.3...

“We do not claim that our whale was a good mimic compared to such well-known mimics as parrots or myna birds,” Ridgway’sCurrent Biologypaper concludes. “However, the sonic behavior we observed is an example of vocal learning by the white whale. It seems likely tha...
compared to ocean where they can swim freely. One the other side, in captivities, the space is limited. Comparatively, to how they swim out in the wild “orcas can swim up to 100 miles per day- a phenomenal amount, in comparison to the exercise they receive in captivity”(Cronin). Whi...
Several scenarios of reconstruction accuracy were compared for the WOA and SHO. The numerical simulations prove that the WOA has a better reconstruction capability. Keywords: inverse scattering; frequency domain; whale optimization algorithm (WOA); spotted hyena optimizer (SHO)...

Ornamented codas have a significantly different ICI distribution compared to regular codas. (Right) Examples of ornaments in the DSWP dataset.EThirty minutes of multi-whale...
Large brain, (im)perfect senses The sperm whale has the largest brain of all living animals.It can weigh 7.8 kg (17 lb) and have a volume of approximately 8000 cm3. Therefore the sperm whale`s brain is 5 times as heavy as a human`s brain. Although size of the brain does affect the...
Killer whales, on the other hand, use twice as much of their cerebellum and are one of the smartest marine mammals, with an intelligence quotient (IQ) of between 4.1 to 4.5, which is compared to that of a 16-year-old human. Sperm whales are smart mammals with the largest brains on ...
