A hyena is a type of pack animal known for its shrewdness and hunting skills and for its disturbing laugh-like call.
Hyenas come in different varieties but commonly have stripes on their fur, weighing about 120 pounds (55 kilograms) and measuring a about a yard (meter) in length. Their fur coloration gives them an advantage when hiding within areas of tall grass.
Hyenas fight in packs and are intelligent enough to send some of the members to circle and flank their prey. They are capable of tripping with their sharp jaws.[
Gnolls, unsurprisingly, have a strong affinity for hyenas, keeping many as pets or guards.
