Hjoula localities, including
Exocoetoides Exocoetoides species could reach a body length of about . The main characteristic of these decidedly small fishes was given by the extreme development of the even fins. In particular, the pectoral fins were particularly long (they could reach the anal region). Also the pelvic fins were large. Moreover the fins were provided with very long rays. In the caudal fin both lobes were the same size. It differs from the closely related
Cheirothrix in having a rounded caudal fin instead of a strongly forked one. In the past it was potentially considered a member of its own family, the Exocoetoididae. Like today's modern-day flying fish they were also likely to perform a sort of gliding flight over water, thanks to the notable expansion of the pectoral and pelvic fins. ==References==
