Sperm whales are believed to prey on the megamouth shark, a rare and large deep-sea species discovered in the 1970s. [165] In one case, three sperm whales were observed attacking or playing with a megamouth. [166] Sperm whales have also been noted to feed on bioluminescent pyrosomes such as Pyrosoma atlanticum.
Livyatan is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod. [1] [8] Diagram comparing the upper and lower size estimates of Livyatan (bottom three) with the size of mature sperm whales, including one of the largest individuals recorded (top three), and a human
Catching peaked in 1902, when 1,305 whales were caught to produce 40,000 barrels of oil. Whale hunting had largely declined by 1910, when only 170 whales were caught. A ban on whaling was imposed by the Althing in 1915. In 1935 an Icelandic company established a whaling station that shut down after only five seasons.
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Sperm whaling involved the above-named ships searching for sperm whales on certain "grounds," or areas where sperm whales were likely to be found, such as the "Western" Ground in the mid-North Atlantic or the "Offshore" Ground in the latitudes of 5–10 degrees south and 105–125 degrees west longitude. The whales were spotted from one of the ...
The recordings represented the voices of approximately 60 sperm whales — a subset of a group of about 400 whales known as the Eastern Caribbean clan — and the vocalizations were recorded ...

American explorer and author J.N. Reynolds published his account, "Mocha Dick: Or The White Whale of the Pacific: A Leaf from a ...
For years, scientists have listened to the clicks of sperm whales and wondered what they were saying. While previous research scratched the surface of understanding, a new study — published May ...
