Figure 2

Percentile ratio of length between verticals through the ADL to TL for anguillid glass eels. The eels were collected at the estuary of the Cagayan River, Luzon Island, Philippines in January and February 2009 (% ADL/TL; mean ± sd). The specimens were divided into three groups by the morphological characteristics: short-fin species (A. bicolor pacifica (a)), long-fin species with developed pigmentation on the tail tip (A. celebesensis, A. luzonensis, and A. marmorata (b)) and long-fin species without pigmentation (A. japonica (c)).
