you’d find that even the blue whale’s organs are huge compared to the sperm whale’s. The heart of a sperm whale is about 4 feet long and over 270 pounds (the average weight of two humans!).
Industrial whaling during the 20th century is arguably one of the most disruptive ecological events caused by humans15, which decimated all great whale species and drove many of them to the brink of extinction16,17. Estimating the decline of whale populations is crucial to evaluate the full impac...
There is a perception that sea otters in California are more susceptible to disease impacts as compared with other sea otter populations. The long-term survival of the sea otter population in California will likely require ongoing research to more effectively characterize current risk factors, and ...
A series of graphs sumamrizing the outcomes of tests of differences in mean relatedness,r, within matrilines compared to meanrbetween matrilines in beluga whale groupings using COANCESTRY v. 1.01.10. Results from a subset of herds with multiple mtDNA haplotypes are shown using the moment estim...
Humpback whales are named, predictably, after an obvious hump in front of their small dorsal fin and are therefore easy to identify compared to some of the other baleen whales. This hump is emphasised when they raise and bend their backs in preparation for a dive. They have dark backs rangi...
Mammals constitute a class of organisms that span an enormous size range of approximately eight orders of magnitude, from 2g in some bats and shrews to 190,000kg in theblue whale. However, the majority of mammals tend toward large sizes compared to other taxa, and they tend to have a corr...
The gentle giants aren't particularly fast when compared to other sharks, but a simple wave of their tail propels them through the water faster than any human could ever swim. They have broad, flat heads and their entire dark-blue bodies are covered in dots that act as camouflage underwate...
Anthropocentric value theory is the idea that humans hold the highest value over all other forms of life, but also that all other life forms have value only inasmuch as they can be used or are important to humans. Non-anthropocentric values, then, allows for the intrin- sic valuation to ...
were positively selected in the whale lineage compared to terrestrial mammals, reflecting the morphological adaptation of the whale to the aquatic environment (Supplementary Fig. 39andSupplementary Note). The adaptations of whales to echolocation (Supplementary Fig. 40), blood clotting (Supplementary Table...
Further, these proposed variants are compared with five well-known parameter extraction models in order to demonstrate their notable advantages over the other existing competing algorithms for minimizing the root mean squared error (RMSE) between experimentally measured data and estimated one. The ...
