Energetics and evasion dynamics of large predators and prey: pumas vs. hounds.

abstract：Background:Saber-toothed mammals, now all extinct, were cats or "cat-like" forms with enlarged, blade-like upper canines, proposed as specialists in taking large prey. During the last 66 Ma, the saber-tooth ecomorph has evolved convergently at least in five different mammalian lineages across both marsupials and placen...
