Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe, with the earliest species known from the Middle Miocene, with the last surviving species (belonging to the genera Smilodon and Homotherium) becoming extinct around Late Pleistocene-Holocene transition (~13-10,000 years ago).
The common name "toothfish" refers to the two rows of teeth in the upper jaw, thought to give it a shark-like appearance. The genus name Dissostichus is from the Greek dissos (twofold) and stichus (line) and refers to the presence of two long lateral lines that enable the fish to sense prey.

The differences in mouth dimensions and tooth length between males and females, and between immature and adult males, could be due to different feeding habits or adaptations for ...
Scyliorhinidae is a family of sharks, one of a few families whose members share the common name catsharks, belonging to the order Carcharhiniformes, the ground sharks. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. [2]

[4] Due to it being both an apex predator and a bottom-dwelling fish, it limits the populations of smaller fish as many catfish species.
According to National Geographic, these fish eat plankton. They also use their sharp teeth to scrape and eat algae from coral reefs. The bulk of the blue tang's diet, however, comes from algae.
