Megan --- We have seen epidemics of diseases with similar symptoms cause
mass mortality of other echinoderms (sea urchins and starfish) elsewhere
in the world. When my colleagues and I tracked the great die-off of
Diadema antillarum through the Caribbean and into the Western Atlantic,
reports like yours were helpful in documenting the pattern of spread,
which better fit a model of spreading contagious disease rather than
models based on chemical contaminants or other physical causes, per se.
If no one is working on this already, recording the timing and spatial
(including geographic) pattern of mortality for the sea cucumbers could
be a valuable learning experience for your students as well as providing
valuable data for persons investigating this disease or the population
biology of the sea cucumbers. --- John
