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!).
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...
In addition, mtDNA damage was also negatively correlated with the expression of the HSP70 chaperone, being higher in sperm whales (most of them dark gray skinned) compared to fin (dark brownish gray skinned) and blue (pale blue-gray skinned) whales, which could suggest an inhibitory effect of...
They are a great and less time-consuming activity as compared to the full subjective or objective tests. Great for topic wise assessments It is recommended to the students revise any topics after the teacher is finished teaching them. This helps them remember tiny details or correct their mistake...
compared to the ocean where they can swim freely. In captivity, space is limited. According to one expert, “orcas can swim up to 100 miles per day- a phenomenal amount, in comparison to the exercise they receive in captivity” (Cronin). While in captivity, an orca has to keep swimming...
38). Additionally, several HOX genes (HOXA5, HOXB1, HOXB2, HOXB5, HOXD12 and HOXD13), which have an important role in the body plan and embryonic development28, were positively selected in the whale lineage compared to terrestrial mammals, reflecting the morphological adaptation of the whale...
The level of male-male aggression in right, gray, and bowhead males is low compared to that seen in humpback whales, also consistent with a reliance on sperm competition rather than contest competition in these species (Brownell and Ralls, 1986). Even in the relatively well-studied mysticetes...
Fig. 4: Increase in putatively deleterious variation in the GOC compared to the ENP fin whales. Sample sizes: Gulf of California (GOC)N = 17, Eastern North Pacific (ENP)N = 27.AThe GOC fin whales contain significantly fewer heterozygous and more homozygous derived genotypes in all...
compared to its relatives and it is the only living member of an otherwise extinct family. This placement makes the pygmy right whale genome an interesting target to update the complex phylogenetic past of baleen whales, because it splits up an otherwise long branch that leads to the radiation...
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 ...
