King rail
This rail forages in shallow water near cover and eats mainly aquatic insects and crustaceans. It forages by probing the mud while moving around in shallow water.
Acorn worm
Many acorn worms are detritus feeders, eating sand or mud and extracting organic detritus. Others feed on organic material suspended in the water, which they can draw into the mouth using the cilia on the gill bars. A groove lined with cilia lies just in front of the mouth and directs suspended food into the mouth and may allow the animal to taste.
