To test the null hypothesis that feeding behavior in aquarium-held whale sharks is not elicited using chemical cues, behavioral responses were evaluated in response to a complex mixture extracted from homogenized krill and to a simple aqueous mixture of dimethyl sulfide (DMS).
Dimethyl sulfide was the only malodorous compound found in significant levels for extra-oral halitosis, whereas methyl mercaptan and hydrogen sulfide were compounds most associated with intra-oral halitosis.
At the same time, phytoplankton would produce dimethyl sulfide, a compound that escapes to the atmosphere and aids cloud formation.
By measuring just two of these compounds, hydrogen sulfide ([H.sub.2]S) and dimethyl sulfide (DMS), a close estimate of the odor concentration could be obtained.
The rotten-egg smell is caused by a gas known as dimethyl sulfide. Scientists already knew that some seabirds, such as albatrosses and petrels, use this smell to locate areas where tiny sea creatures called phytoplankton live.
Methyl mercaptan, C[H.sub.3]SH, (MESH) is a central nervous system depressant; dimethyl sulfide, [(C[H.sub.3]).sub.2]S, [(DMS) is a serious eye irritant; dimethyl disulfide C[H.sub.3]).sub.2][S.sub.2], (DMD8) may be fatal if inhaled.
Confined to her bunk to recuperate from her injury, she realized she could easily smell the dimethyl sulfide (DMS) that an atmospheric chemist on board was using for experiments.

Sulfur-containing compounds, such as dimethyl sulfide, are thought to be markers of liver disease (12,13).
It seems that warming increases the amount of oceanic phytoplankton, which, in turn, produces more dimethyl sulfide (DMS).
The same wide diffusion is true of the dimethyl sulfide released from oceans worldwide.
