The occurrence and dynamics of clutch loss and filial cannibalism in two Caribbean damselfishes
CW Petersen - Journal of Experimental Marine Biology and Ecology, 1990 - Elsevier
Field populations of two Caribbean damselfishes. Stegastes dorsopunicans (Poey) and
Microspathodon chrysurus (Cuvier), were monitored for 7 months to determine if complete
clutch cannibalism by paternal males occurs and to quantify what types of clutches were
most vulnerable to cannibalism by the parent. In both species, filial cannibalism was
confirmed by both direct observations and analysis of gut contents in guarding males whose
clutches had disappeared prematurely. Smaller younger clutches were more likely to be …
