Pronunciation: [antˈɑːktɪk tˈuːθfɪʃ] (IPA) 
The correct spelling of the fish species often referred to as Antarctic toothfish is "Dissostichus mawsoni". The word "toothfish" is a common name given to several species of fish in the genus Dissostichus. The correct pronunciation of the species is /ˌænˈtɑːktɪk ˈtuːθfɪʃ/, with stress on the second syllable of "Antarctic". The "t" in "Antarctic" is aspirated, meaning it is pronounced with a slight puff of breath.
The Antarctic toothfish, also known as Dissostichus mawsoni, is a species of deep-sea fish that belongs to the family Nototheniidae. It is commonly found in the cold waters surrounding Antarctica, particularly in the Southern Ocean. The Antarctic toothfish is a large and predatory fish, with an average length ranging between 1.5 to 2 meters and a weight of approximately 100 kilograms. It possesses a unique set of teeth that are sharp and pointed, resembling those of a mammal's canine teeth, hence its name.
This species has a slender and elongated body, which is well-suited for its deep-water environment. Its coloring varies from dark brown to black, enabling it to blend in with the deep-sea surroundings and camouflage itself from potential prey. The Antarctic toothfish is known for its endurance and ability to survive in extremely cold waters, thanks to its high fat content and antifreeze proteins in its blood.
Due to its large size and high oil content, the Antarctic toothfish is a prized catch for commercial fishing. It is sought after for its succulent flesh and is commonly marketed as "Chilean sea bass" or "white gold." However, the species is also subject to overfishing, leading to concerns about its long-term sustainability. Consequently, international regulations and protective measures have been put in place to ensure the conservation and management of the Antarctic toothfish population.
The word "Antarctic toothfish" has a relatively straightforward etymology.
"Antarctic" refers to its geographical location and habitat. The term is derived from the Greek words "antarktikos", meaning "opposite to the Arctic", and "arktikos", meaning "of the north". The Antarctic toothfish is found in the Southern Ocean surrounding Antarctica.
"Toothfish" is a compound word that describes the fish's teeth. The name "toothfish" is said to originate from the fish's prominent, sharp teeth, which are used for capturing prey. This name distinguishes it from other fish species that may have different dentition. It is worth noting that the Antarctic toothfish was initially known as the "Chilean sea bass" in the culinary world, but the name was changed in order to promote more sustainable fishing practices and reduce consumer confusion.
