The interhyal and epihyal begin ossifying at 17 DPH followed by the ceratohyal and basihyal at 23 DPH.
Consequently, Rivulus was considered to be the sister group to a clade including "Rivulus" and all other rivulids, which was diagnosed by an apomorphic cartilaginous interhyal (vs.
Costa (1990), in a phylogenetic analysis based on morphological and behavioural traits, confirmed the presence of an ossified interhyal in some species then placed in Rivulus, but demonstrated that the number of seven pelvic-fin rays is not informative to define a rivulid clade.
cylindraceus, the type species of Rivulus, not available in the previous study, has a cartilaginous interhyal.
