Blue Planet: The Coral Seas

A lot of sea creatures benefit from living on other animals and vice versa. One relationship that was particularly interesting was the microscopic shrimp that lived in the tunnels inside of a particular coral. The shrimp would protect the coral by snipping at intruders and the coral would provide the shrimp with everything they would need to live without leaving its tunnels.

The shrimp are nearly transparent.
This is the Queen shrimp with all the itty babies!!
