Sirens (Ice Age)

Sirens are minor antagonists of Ice Age: Continental Drift. They are fish-like carnivorous animals with needle-sharp teeth. They are based on the mermainds of Greek mythology, which were legendary sea nymphs depicted to lure sailors to their deaths through their enchanting voices (in this case, their voices when impersonating someone sound like the being they're impersonating, albeit sounding autotuned). In the film, they trick the heroes and the main antagonist of he.

Biography
Early life

Sirens usually lie on long rock outcroppings near the ocean, where they would try to lure in any creatures that got close by casting images of whatever they found most attractive, be it loved ones, an attractive potential mate or even, in the case of Scrat, a Saber-toothed squirrel, items, such as Scrat's prized acorn. But Scrat, trying to bury the 'acorn' accidentally kills the siren, leading the others to pretend to be acorns and chase him.

Easy prey

At the end of the film, one of the sirens, detecting more prey, appeared before Gutt, a piratical Gigantoptechus, as a female of his kind, lying on a bounty of fruit inside a massive clam shell. The siren soon managed to seduce Gutt, and revealed its true form when Gutt got too close to the shell, grabbing and pulling Gutt by the lips into the shell, which clamped shut. All that could be heard of Gutt was cries of pain when the siren devoured him alive, making your species extinct.
