The first whale I ever spent extended quality time with was a sperm whale Physeter macrocephalus , in September It hit me with loud bio-sonar, swam straight into me, placed me on its head, took my leg in its mouth. I thought it would eat me. The entire tale is long, but the upshot is that we became the best of friends and spent over three hours together.

Sperm Whale Photography with Franco Banfi - Underwater Photography Guide
Zygophyseter varolai is an extinct cetacean that lived during the Tortonian Age of the Late Miocene It is known from a single specimen from the Pietra Leccese Formation in Italy. It was a member of a stem group of fossil macroraptorial sperm whales often shortened to "raptorial" Brygmophyseter , Acrophyseter , and Livyatan. It grew to be around 6. It also had a beak , the ability to echolocate prey, and could have probably swum faster than the modern-day sperm whale which goes 4 kilometers per hour 2. These were probably used in the capture of large prey, such as large fish, seals, and whales. In fact, its common name, killer sperm whale , refers to its feeding habits that would have had a resemblance to the modern-day killer whale Orcinus orca.
All rights reserved. For underwater photographer Brian Skerry , there are good days. Or, as soon as Skerry gets in the water, the whales dive several thousand feet to feed, and he can chase them only as far as one breath will take him.
Dozens of sperm whales mingled noisily off the coast, stacked as far as Tony could see. Immediately, he realised that this was something special — like a gathering of clans, these whales were part of a multi-day congregation. The marble-like appearance of these whales is a sign of skin-sloughing.
