Coughlin,-D.J.; Strickler,-J.R.  Zooplankton capture by a 
	coral reef fish: An adaptive response to evasive prey. 
	ENVIRON.-BIOL.-FISH. 1990. vol. 29, no. 1, pp. 35-42.

High-speed cinematography and video using modified Schlieren 
optics and laser illumination helped elicit details of prey 
capture mechanisms used by Chromis viridis  while feeding on 
calanoid copepods and Artemia . Chromis viridis  is capable 
of a ram-jaw, low-suction feeding, as well as a typical 
suction feeding behavior described for other species of 
planktivores. By adjusting the degree of jaw protrusion and 
amount of suction used during a feeding strike, this fish can 
modulate its feeding strikes according to the prey type being 
encountered. The ram-jaw feeding mode enables C. viridis  to 
capture highly evasive calanoid copepods within 6 to 10 msec. 
The use of specialized feeding behavior for evasive prey and 
the ability to vary feeding behavior are adaptations for 
feeding on evasive prey.
