Scrimshaw was the art of engraving on the teeth of sperm whales. It was a way for whalers to pass the time between hunts. The sperm whale's ivory-like teeth were often sought by 18th- and 19th-century whalers, who used them to produce inked carvings known as scrimshaw. 30 teeth of the sperm whale can be used for ivory. Each of these teeth, up ...
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

The front teeth were more worn on the sides, whereas the lower teeth were more worn along the middle. [2] A. deinodon had 12 teeth in the upper jaw and 13 teeth in the lower jaw and possessed tooth enamel like other macroraptorial sperm whales. The premaxillae bore three teeth, and the maxillae had nine teeth. Unlike in other sperm whales, the ...
And sperm whales function as a family, "Sperm whales are often spotted in groups (called pods) of some 15 to 20 animals. Pods include females and their young, while males may roam solo or move ...
Macroraptorial sperm whales occupied the same niche as killer whales (Orcinus orca). Using their large and deeply rooted teeth, wide-opening jaws, and great size, they likely fed on a variety of sea life, including fish, cephalopods, seals, and small whales and dolphins, occupying a niche similar to the modern day killer whale (Orcinus orca).
Generally their teeth have evolved to catch fish, squid or other marine invertebrates, not for chewing them, so prey is swallowed whole. Teeth are shaped like cones (dolphins and sperm whales), spades , pegs , tusks or variable (beaked whale males). Female beaked whales' teeth are hidden in the gums and are not visible, and most male beaked ...
The ancient shark, which grew up to 65ft long and weighed over 50 tons, ate sperm whales by ripping off their heads with its huge teeth, a new study has shown.
What sperm whales are saying with their clicks remains a mystery to human ears. Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to ...
