An integrative investigation of sensory organ development and orientation behavior throughout the larval phase of a coral reef fish.

The dispersal of marine larvae determines the level of connectivity among populations, influences population dynamics, and affects evolutionary processes. Patterns of dispersal are influenced by both ocean currents and larval behavior, yet the role of behavior remains poorly understood. Here we report the first integrated study of the ontogeny of multiple sensory systems and orientation behavior throughout the larval phase of a coral reef fish-the neon goby, Elacatinus lori.

Parasitism has evolved innumerable times among eukaryotes. Red algal parasites alone have independently evolved over 100 times. The accepted evolutionary paradigm proposes that red algal parasites arise by first infecting a close relative and over time diversifying and infecting more distantly related species.
