  3. COMMENSALISM • “Good for me, doesn’t bother you! Example: Hermit Crab and Snail Remora and Shark A hermit crab lives in shells that are made and then abandoned by snails. This neither harms nor benefits the snail. A remora attaches themselves to a shark’s body. They travel with the shark and feed on the left over food from the shark’s meals. This does not hurt or help the shark.

  4. MUTUALISM “Good for you, good for me! Example: Ostrich and Gazelle These two animals feed next to each other in the grasslands. Both watch for predators and alert each other to danger. The visual abilities of these two animals are different so they are able to identify threats the other animal would not see.

  5. Parasitism • “Good for me, hurts you!” Example: Cuckoo and Warbler Deer and Tick A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will displace the warbler’s young and will be raised by the warbler. A tick feeds on deer blood to the detriment of the deer.
