Ecology Summary - Sparisoma radians

Language:

Main Ref.	Randall, J.E., 1967
Remarks	As an adult, it lives among seagrasses (Also Ref. 128694) and feeds on them. When alarmed, S. radians follows an escape pattern of darting rapidly away and suddenly coming to rest motionless in the seagrass, where it assumes a mottled color pattern that makes it difficult to detect (Ref. 35209). Feeds primarily on epiphytes and seagrass blades, leaving crescent bite marks. Herbivore (Ref. 57616).
