"Orcas and other cetaceans are actually more vulnerable to stress in entertainment parks because of their cognitive complexity," she told Gizmodo.
|
|
Cetaceans are social creatures that live in groups, and it's possible that one confused whale can lead an entire pod astray.
|
|
The whales have been in decline for decades, largely because the nutritious salmon the toothed-cetaceans rely on have been overfished.
|
|
Instead, cetaceans, the group including today's whales and dolphins, evolved 50 million years ago from small four-legged animals with hooves.

A small local fleet has survived by hunting cetaceans not covered by the IWC, such as dolphins and Baird's beaked whale, and by conducting "research" of its own.
|
|
Anyway, the killer whale in France is certainly doing some form of mimicry, and perhaps cetaceans mimic in the wild, too, creating entirely new dialects of blowhole farts.
|
|
For many of the same reasons as orcas, most marine scientists agree that cetaceans can never thrive in captivity, where their environment, stimuli, and social bonds are gravely limited.

The discovery of Coronodon helps us understand how cetaceans evolved — showing that ancient whales developed their "filter feeding" behavior before developing the baleen used today to filter water for food.
|
|
The only thing worse than the sonar and pollution of mayhem we have poured into the seas, would be the loss of the cetaceans, which would silence the oceans forever.
|
|
And the harm done to the ocean can, in turn, negatively impact the economies that depend on it, as commercial fisheries are disrupted or tourism is impacted due to cetaceans declines.

This unparalleled database of killer whales was an important strength of the study, said Ruth Esteban, who researches killer whales with Conservation, Information and Research on Cetaceans in Spain, and did not participate in this research.
|
|
Though several groups have argued that dolphins and other cetaceans deserve some sort of legal rights under a category such as "non-human persons," there has been no actual ruling or law classifying them as such.
|
|
But as paleontologists are learning from the fossil record, these strange, hard-to-find cetaceans are the descendants of a much larger group that went from sea to land multiple times, for reasons that are still unclear.
|
|
The size of cetaceans' organs is also "pretty variable," she told me: A harbour porpoise has a penis the "length of my forearm," she explained, whereas the common dolphin's is about the size of a human hand.
|

Results taken from 0003 programs to reliably count by-catch between 1981 and 2016–carried out in Australia, Sri Lanka, India, and Pakistan–were used as the basis to extrapolate how many cetaceans were caught across all Indian Ocean fisheries covering 24 countries.
|
|
Other, less mistake-prone enzymes are still found in cetaceans; this led the researchers to conclude that the gene for the messy enzyme may have been discarded because, in a living situation with frequent DNA repair, it did more harm than good.

Looking at this ratio over a large number of vertebrate animals, he said, scientists have found that "brain size increases pretty linearly with body size, except for some critical species like Homo sapiens and some cetaceans," the order of mammals that includes whales, dolphins and porpoises.
|
|
As he converses chummily with fishermen and other townspeople, justifications for the hunt emerge: Taijians love cetaceans so much they construct festivals and religious rituals around them; eating their meat is a 400-year-old cultural tradition; the species caught in Taiji are not currently endangered.
|
|
In the 1970s, for instance, US federal researchers concluded the Bering Sea's bowhead whale population was shrinking, prompting the International Whaling Commission, a global organization that manages whale conservation and whaling, to impose drastic hunting restrictions on indigenous communities that depended on the cetaceans for sustenance.

Despite all the sharks and stingrays I had seen, they trounced me with a recollection of the music—either snoring or song, they weren't sure which—that had come from the humpback whale idling beneath them as they hovered below surface on the cetaceans' migration route in the channel between Tahiti and the neighboring island of Moorea.
|
