Three Types of Symbiosis

ParasitismCommensalism

Mutualism

The aphid gets protection from the ant against predatory insects like ladybugs.

The Hippo and The TurtleA baby hippo, near certain death, was found near the ocean

in Africa. It was rescued and placed in a reserve area, where it immediately began following around a huge turtle. The turtle hissed at him first, but finally gave in and let the baby hippo hang out. In days, they became inseparable. They ate, bathed in a nearby spring, and slept together.

What kind of symbiotic relationship do they have?
