Both are schooling rabbitfish with venomous spines. Streamlined Spinefoot is slimmer, blue to grey above and silvery below, with small yellow spots and wavy lines on the lower sides, a yellow armpit behind the pectoral fin, a yellow stripe along the base of the dorsal fin and a deeply forked tail. Mottled Spinefoot is olive-green to brown with small pale blue spots, and its tail is less deeply forked.
