10/17/05 - First sub dive


pulling in a net We are in the gorgeous blue Gulf Stream! The night watch worked through the evening, putting Neuston nets in about every 15 minutes. They caught several leptocephali (larval eels). Eels have one of the most unusual larvae of any fish They are thin and clear—like skinny see-through fettuccini— with eyes, a mouth, and a visible intestinal track. Some of these larvae travel great distances to return to freshwater where they mature. They are quite difficult to identify. Some species spend a long time, from several months to years, before maturing. We don't know how they feed.

Steve Ross was in the bow of the sub and Martha Nizinski in the stern for Monday morning's dive. They encountered a fairly stiff current which made traveling along the bottom fairly difficult. They returned to the surface with some coral samples and a few crabs and urchins. While the sub battery charged we deployed the Neuston net several times and caught a small Portugeuse Man-of-War, some crabs, and a few small fish.

The night shift is busy deploying the Neuston net and looking forward to a productive evening.
