Functional morphology, ecology, and systematics of fishes. Most of my research is done at the Friday Harbor Marine Lab in Washington state. I'm investigating resource partitioning in surfperches, a family of nearshore fishes common along the west coast of North America. Surfperches give birth to live young that are extraordinarily well developed - a 17 cm female may have as many as 30 6 cm young! As adults, surfperches show a variety of morphological and behavioral feeding specializations (compare the size of the pharyngeal "jaws" in the throats of the two species in the X-ray). Recently, I've been investigating the extent and importance of morphological differences among newborns of different species (such as the two in the left photo).
