Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in every continent except for Australia and Antarctica. The earliest species is known from the Middle Miocene, while the latest species Smilodon populator survived up to the Early Holocene (8,200~9,100 years ago).

Shark Anatomy (50693674756) The gill slits of a whale shark flaring as it expels water from its pharyngeal cavity. In the shark anatomy image, it depicts the beginning half of the shark, including the gills. The shark gills are especially important and were evolved from the chordate pharyngeal gill slits synapomorphy.
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.
Researchers have discovered evidence pointing to the first known case of a porbeagle shark — which can grow up to 12 feet long and 500 pounds — being killed by a large shark predator.
The tiger shark is the only species in its family that is ovoviviparous; its eggs hatch internally and the young are born live when fully developed. [7] Tiger Sharks are unique among all sharks in the fact that they employ embrytrophy to nourish their young inside the womb. The young gestate in sacks which are filled with a fluid that nourishes ...
