Frogfish Spawning

On the nights of the 1st and 12th of May 2005 in Bonaire, I witnessed two pairs of Frogfish spawning. On both occasions, the smaller male was close to the female and started pushing her egg swollen belly. The pairs rose 1 foot (30 cm) above the reef where, in a flash, spawning occurred. The couples then drifted back to the reef while the eggs, released in a roll, slowly unfolded into a raft in a graceful dance to the surface.  Tide, wind and current then decide the fate of the eggs. This experience was one of the most special moments in my life.
