Ambergris in dried form. Ambergris (/ ˈ æ m b ər ɡ r iː s / or / ˈ æ m b ər ɡ r ɪ s /; Latin: ambra grisea; Old French: ambre gris), ambergrease, or grey amber is a solid, waxy, flammable substance of a dull grey or blackish colour produced in the digestive system of sperm whales. [1]
Spermaceti / s p ər m ə ˈ s iː t i ˌ-ˈ s ɛ-/ is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantities, in the oils of other whales). Spermaceti is created in the spermaceti organ inside the whale's head. This organ may contain as much as 1,900 litres (500 US gal) of spermaceti. [1]
The uses for the spermaceti organ in Livyatan are unknown. Much like in the modern sperm whale, it could have been used in the process of biosonar to generate sound for locating prey. It is possible that it was also used as a means of acoustic displays, such as for communication purposes between individuals. It may have been used for acoustic ...
"Whale pump" – the role played by whales in nutrient recycling in the oceans (based on Fig. 1 of Roman & McCarthy (2010) [1]) Whale feces, the excrement of whales, has a vital role in the ecology of oceans, [2] earning whales the title of "marine ecosystem engineers." This significant ecological role stems from the nutrients and compounds ...
The spermaceti organ in sperm whales is shaped like an elongated barrel and sits on top of the whale's melon. Historically, the spermaceti oil found within it was used in a variety of products – including lamp oils, candles, and lubricants – providing the economic basis for the sperm whaling industry. [ 2 ]
Pure research uses larger numbers and a greater variety of animals than applied research. Fruit flies, nematode worms, mice and rats together account for the vast majority, though small numbers of other species are used, ranging from sea slugs through to armadillos. [190] Examples of the types of animals and experiments used in basic research ...
Shore-based work on South Georgia took place in the marine laboratory, Discovery House, built in 1925 at King Edward Point and occupied until 1931. The scientists lived and worked in the building, travelling half a mile or so across King Edward Cove to the whaling station at Grytviken to work on whales as they were brought ashore by commercial whaling ships.
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...
