The phylogenetic position of needlefishes relative to halfbeaks fits his prediction. |
In flyingfishes, and in some halfbeaks such as Arrhamphus, the extended lower jaw is lost in adults. |
There are predators that take advantage of this nocturnal foray besides halfbeaks and anchovies. |
Flyingfishes are nested within halfbeaks, and sauries are nested within needlefishes. |
Halfbeaks were sampled aboard commercial fishing vessels, and during fishery-independent trips, to determine spatial and temporal spawning patterns of both species. |
Instead, our hypothesis suggests that halfbeaks are relatively basal members of Beloniformes, and the needlefish morphology is relatively derived. |
