One behavioral adaptation to avoid predation is mobbing behavior. In this scenario members of the prey species cooperatively attack or harass the predator. This is demonstrated in social animals such as birds. Seahorses swim upright with their tails down, heads up. They employ a sit and wait strategy remaining motionless until prey swim by and they snap and draw prey into their mouth. Besides this being an excellent strategy for them to obtain food, while remaining motionless, they are also evading predators! Decorator crabs are able to use materials in their surroundings to hide. When they grow, they must molt and they shed their old shell. They even use the sponges and other decorations from the previous shell to decorate the new one!
Many animals develop behavioral adaptations in order to escape predators. Animals learn a particular behavior because it can help them hide or escape.
Birds, fish, and whales all migrate as a behavioral adaptation. Some of these animals migrate for food or climate control. Others migrate to escape the predators that seek their natural habitats.
Seahorses have found a different behavioral adaptation. They use their tails to grab onto seaweed. Many of their natural predators cannot swim well in deep, tangled webs of seaweed. The seahorse is then protected by this grasping behavior.
While some animals attach themselves to their habitat, other animals try to blend in. The decorator crab is a great example of animal using camouflage. This crab takes bits of seaweed, discarded shells, and whatever else it can find on the ocean floor. It will cover it's shell in these bits in order to blend in with its environment. While the barbs on its shell that hold these bits in place are a structural adaptation, the acts of collecting and covering the shell are behavioral adaptations.
