Whale bone was ideally suited for the task, as it is easy to work and was plentiful. The widespread carving of scrimshaw was enabled when the 1815 publication of the journal of U.S. Navy Captain David Porter disclosed both the market and the source of the whale teeth, causing a surplus of whale teeth that greatly diminished their value and made ...
Now, sperm whales are protected under the Marine Mammal Protection Act. So, in order to sell the animal's tooth, it must be over 100 years old, and the owner has to know where it's been since the ...
Megalodon apparently further refined its hunting strategies to cope with these large whales. Numerous fossilized flipper bones and tail vertebrae of large whales from the Pliocene have been found with megalodon bite marks, which suggests that megalodon would immobilize a large whale before killing and feeding on it.

Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding.
A large number of whales visiting the waters off New England included an uncommon sighting of an orca eating a tuna and an unusually large group of an endangered species of whale, scientists said.
The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair. Baleen is a skin derivative. Some whales, such as the bowhead whale, have
Fewer than 400 individual North Atlantic right whales remain in the wild, and their numbers continue to decline. Oceana , a conservation group based in D.C., has reported numerous collisions ...
