Echinoderms are fundamentally good indicators of health and status of coralline communities in marine waters. In this study, the diversity and distribution of echinoderm species were determined in Babanlagan, Talisayan, Misamis Oriental. In total, 387 individuals were collected coming from classes Echinoidea, Holothuroidea, Asteroidea, and Ophiuroidea. The majority of individuals collected were Protoreaster nodusus, which is a good indicator of reef health while the least abundant echinoderm species was Acanthaster planci. The pattern of distribution of majority of echinoderms was a clumped distribution while the other groups followed regular/uniform distribution, which may be due to limited dispersal ability and availability and available food sources. Moderate species diversity was also observed and species were rather similar in abundance, shown by the evenness index. This suggests good marine health, even under the threat of gleaning activities, active fishing, and habitat destruction. It is recommended that follow-up studies are conducted especially regarding monitoring of echinoderm species, to further assess the health of the intertidal zone in Babanlagan, Talisayan, Misamis Oriental.
