The prodigal fish

Article Abstract:

It has been established that some of the larvae of reef fish remain near where they are spawned, settling back onto the island reefs inhabited by the parents rather than being washed away by ocean currents. This research showed that the larvae of the Caribbean bluehead wrasse frequently spend their planktonic lives close to shore. This conclusion was reached on the basis of extremely small chemical tags that accumulate inside the otolith. The researchers measured the elemental content of otoliths collected from settling wrasse larvae in the US Virgin Islands to determine where larvae had drifted.
