A remarkable new study on how whales behaved when attacked by humans in the 19th century has implications for the way they react to changes wreaked by humans in the 21st century.
The paper, published by the Royal Society on Wednesday, is authored by Hal Whitehead and Luke Rendell, pre-eminent scientists working with cetaceans, and Tim D Smith, a data scientist, and their research addresses an age-old question: if whales are so smart, why did they hang around to be killed? The answer? They didn’t.
Using newly digitised logbooks detailing the hunting of sperm whales in the north Pacific, the authors discovered that within just a few years, the strike rate of the whalers’ harpoons fell by 58%. This simple fact leads to an astonishing conclusion: that information about what was happening to them was being collectively shared among the whales, who made vital changes to their behaviour. As their culture made fatal first contact with ours, t

Cetaceans are the longest-living animals in general, with some whale species surviving to over 200 years old. Given their size, their bodies contain much more cells than the human body. It s a wonder how this is possible.

Despite being astoundingly huge, Cetaceans, on the other hand, have significantly lower cancer rates than most other animals, including humans. The case can be seen as an example of Peto s Paradox.
(MENAFN - Emirates News Agency (WAM)) FUJAIRAH, 16th February, 2021 (WAM) New aerial and boat surveys offshore Fujairah have shed new light on the presence of cetaceans (whales and dolphins) off the UAE s East Coast, according to the Fujairah Whale and Dolphin Research Project.
Operating under the patronage of the H.H. Sheikh Mohammed bin Hamad bin Mohammed Al Sharqi, Crown Prince of Fujairah, the research is jointly undertaken by the Port of Fujairah and Five Oceans Environmental Services. It is the only project in the region which focusses research specifically on marine mammals in deep, offshore waters.
The 2021 survey season, which began earlier this month, has so far included multiple aerial surveys and boat surveys in waters between 10 and 30 nautical miles offshore Fujairah.
