The payara, which is also sold as the saber tooth barracuda, vampire fish, vampire tetra, or saber tusk barracuda, is a popular species for large, aggressive aquariums. It requires a large aquarium and can only be mixed with relatively large species, as smaller will be seen as potential prey. [4]
Hydrolycus armatus is a species of dogtooth characin found in freshwater of tropical South America. [2] It is sometimes known as Payara, [1] or harm, [3] [4] [5] a name it shares with the related H. scomberoides.
Sabertooth fish are usually a drab, light to dark brown when preserved; however, a brassy green iridescence is seen on the flanks, cheeks, and ocular region of well-preserved specimens. The naked skin is easily torn. The Atlantic sabertooth (Coccorella Atlantica) is the largest species, at up to 18.5 cm standard length.

Machairodus (from Greek: μαχαίρα machaíra, 'knife' and Greek: ὀδούς odoús 'tooth') [2] is a genus of large machairodont or ''saber-toothed cat'' that lived in Africa, Eurasia and North America during the late Miocene. It is the animal from which the subfamily Machairodontinae gets its name.
The carcass of a large cub estimated to be about 3 weeks old was found encased in a block of ice in the Republic of Sakha, located in Russia's Far East, along the Badyarikha River in 2020 ...
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).
A new point-to-point bite model is introduced in the article by Andersson et al., showing that for saber-tooth cats, the depth of the killing bite decreases dramatically with increasing prey size. [10] The extended gape of saber-toothed cats results in a considerable increase in bite depth when biting into prey with a radius of less than 10 cm.
