Figure 7

Ontogenetic growth curves of the eyes of the surface catfish Rhamdia laticauda (Pimelodidae) and two of its cave derivatives (R. zongolicensis and R. reddelli). Each symbol indicates eye size (measured as eye diameter) and body length (measured as standard length) of one specimen. Connecting lines indicate left–right asymmetry of the eye rudiments found in one single specimen. Insert showing eye growth up to 10-mm body length (from Wilkens, 2001).
