Small raptor-like creature

Deep green like the forest

Like a classical raptor ala Jurassic Park

Small, standing straight they are 4ft

Small sharp claws and razor sharp teeth

They have a hardened leather hide, great at protecting against slashes

Hyper-Aggressive, they attack everything except their own

Full frontal assault, they throw bodies until they overwhelm or lose too many

Sheer numbers deters most attackers, and they attack anything

They're about as dexterous as ostriches

Numbers and claws/teeth

No remorse or mercy, they have no friends but their own. They also are almost useless alone

Sharp high-pitched clicking noises

Tough leathery hide, Blade-like teeth, Stringy but surprisingly tasty meat

The huge forests

Various wildlife in the forest, sometimes the abominations too

Rapidly, constantly. They are mammals, but gestation takes days
