Salangidae

Salangidae View in CoL View at ENA ( Osmeriformes ) ( Fig. 10 View Figure 10 )

In Salanx acuticeps and Protosalanx chinensis two CMCs are present ( Fig. 10 View Figure 10 ). They are usually of similar size with the upper one only slightly smaller than the lower one. In some individuals, not depending on species, the upper CMC is very small ( Fig. 10A View Figure 10 ). The cartilages are roughly triangular when seen from the posterior side with their edges bent anteriorly, thus forming a cap on the diastemal edge of hypural 2 and 3, respectively. Each CMC supports a fin ray: the lowest of the upper lobe and the upper most of the lower lobe ( Fig. 10B, C View Figure 10 ). There are no medially directed pegs on the rays in the studied salangids.
