About me
I am interested in phenotypic diversity and population dynamics of fishes, generally in relation to habitat selection, foraging and adaptation.

Atavism in the threespine stickleback, Gasterosteus aculeatus: four dorsal spines. * = additional dorsal spine.
Breeding tubercles of a nase, Chondrostoma. Skin is stained blue, the tubercles pink.
Schindleria, Infant fishes, are extremely progenetic gobiid fishes with a very fast generation time, up to nine generations the year. Different coloration is due to different preservation. Scale bar = 1 mm.
Osteological atlas of Quietula guaymasiae, a gobiid fish from the Eastern Central Pacific. Fig. 32: Jaws, suspensory and opercular series in lateral view. Scale bar = 1 mm.
Innervation of the free neuromasts of Lythrypnus dalli, a gobiid fish from the Eastern Central Pacific. Scale bar = 5 mm.
