Physical Adaptations

Males have a pair of horns that help them protect their habitat. They

pluck their tongue while they eat, this helps the Okapi handle their food. Okapi

rely a lot on their sharp hearing to warn them of danger. If predators were to sneak up behind them they would be able to hear them ahead of time and run away to safety. They are able to pick up even the softest of sounds with their sensitive ears. Their long necks help the Okapi to reach the majority of their body, so they can keep themselves clean. Okapi have a great camouflage to help them blend with their environment. Their stripes also help the young follow their mom through the rain forest at night. Having a very oily skin helps the water slide off quickly keeping them dry.

Behavioral Adaptations

They tend to use their hind legs to kick at an aggressor, this is how they protect themselves from predators. Male Okapi mark their territory with their urine, this action tends to defend against predators and warn anyone other male Okapi not to enter their territory. They communicate by vocal sounds. As if they were to have a special call for being in danger. Their not very social animals, they tend to feed in small groups for just a short amount of time. The alpha male of the group sticks its neck up high to let the rest of the herd know who is the boss. Okapi occasionally like to social groom (pick bugs off of each other) to clean each others body.
