Field Frame Friday: Dimethylsulfoniopropionate: what a mouth full… of food.

DCIM\101GOPRO\G0686420.

Bluefin trevally (Caranx melampygus) or ‘omilu in Hawaiian are able to detect dimethylsulfoniopropionate (say that 5 times fast, or just say DMSP). DMSP is a chemical produced by phytoplankton (marine algae) that is an indicator of food productivity. This chemosensory adaptation is important for foraging success!
