Should the schizomid not retreat, it will lunge forward and seize its victim with its palps. [15] The prey is then subdued, and possibly taken to the shelter of a nearby crevice to be eaten. [ 15 ] The chelicerae dismember the prey item before the tissues are liquified into chyme and ingested via suction with the mouth.
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.
Kogia is a genus of toothed whales within the superfamily Physeteroidea comprising two extant and two extinct species from the Neogene: Pygmy sperm whale, Kogia breviceps; Dwarf sperm whale, Kogia sima †Kogia pusilla, Italy, Middle Pliocene †Kogia danomurai Pisco Formation, Peru, latest Miocene
Kogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales.As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales.

He was found still living days later in the stomach of the whale, which was dead from harpooning. The story originated of an anonymous form, began to appear in American newspapers.
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).
Historically, whaling took a heavy toll on sperm whale populations. Prior to the early 18th century, sperm whales were hunted in Japan and Indonesia. Legend has it that sometime in the early 18th century, supposed to be not far from 1712, Captain Christopher Hussey, while cruising for right whales near shore, was blown offshore by a northerly wind, where he encountered a school of sperm whales ...
Owen Chase (October 7, 1797 – March 7, 1869) was first mate of the whaler Essex, which sank in the Pacific Ocean on November 20, 1820, after being rammed by a sperm whale. Soon after his return to Nantucket , Chase wrote an account of the shipwreck and the attempts of the crew to reach land in small boats.
