The Needlejaw is a 4 foot tall quadrupedal omnivore inhabiting the dense red-leaved woodlands of a small fertile world. During the forty-hour periods of daylight it divides its time between resting, and tracking down fruits and soft plants with its keen sense of a smell, peircing them with its hardened rostrum and sucking out the fluids.
As darkness descends however, its behaviour changes dramatically: Antennae previously held furled against the head are deployed and are able to detect the infrared radiation given off by its warm-blooded prey in the darkening forest. Using its slender legs and light build, the Needlejaw stalks silently until near enough to strike, driving its pointed beak downward with enough force to pierce tough skin and inject potent toxins and enzymes. The wounded prey is then tracked by the Needlejaws’ keen sense of smell, and drained of its body fluids by a strong muscular pharynx.
Powerful, sharp edged claws usually held flat against the chest are used to manipulate prey to facilitate feeding, or to tear open organs and other tough tissues. They are also utilised in carrying prey to a safer feeding location, where it will be protected from other, larger predators.
This ability; to exploit different food resources during both day and night cycles, has allowed the Needlejaws to diversify greatly, and the group is found in large numbers in many habitats across the planet.
