Algae grows on manatee's skin. The manatee is not affected.
These beautiful Bromeliad plants use their specialized roots to cling to tree trunks and branches taking nothing but support from trees; drawing their water and nutrients from air and moisture that accumulates between their leaves like tiny little cups, storing water for later.
Cordyceps fungus infiltrate their insect host, where their hyphae then grow into the insect's body and absorb nutrients from non-essential organs while controlling the insect's brain. When the fungus is ready to reproduce, it directs its host to march to a cool, moist location in the forest where spores erupt through the insect’s head to spread in the wind.
Orca whales hunt seals, sharks, and penguins for their food.
Ticks feed on the blood of larger hosts for sustenance and survival. Saliva from infected ticks can also transmit disease-causing pathogens into the host.
A pride of lions attack an elephant, providing food for the members of the pride.
Aphids produce a sugary substance that ants love. Ants protect the aphids from predators and parasites.
Red-billed oxpeckers travel around on herd animals and eat ticks and parasites living on the herd animal's skin. The birds get food, and the herd animals get pest control.
In the ocean, then anemone protects clownfish with its toxic tentacles and the clownfish rids the anemone of parasites and feeds it with fish poo.
A house cat hunts mice hiding in the house, killing and eating it.
