Abstract

Thalassia
testudinum
, which is commonly grazed by
Tripneustes ventricosus,
is located throughout the Caribbean. Discovery Bay, Jamaica is home
to nitrogen-enriched
Thalassia
testudinum
while in other areas of the
Caribbean the
Thalassia testudinum
is not nitrogen-enriched. The main focus of this experiment was to
see whether or not
Tripneustes
ventricosus
would prefer to consume the
nutrient rich
Thalassia testudinum
found in the lagoon of Discovery Bay over the
Thalassia
testudinum
found outside the lagoon.
Tripneustes ventricosus
were collected for this experiment as well as
Thalassia
testudinum
from inside and outside the
lagoon of Discovery Bay and were put into artificial environments
designed to test their preferences.
After 3
trials, with trials 2 and 3 having a no-light factor, our data
indicated that
Tripneustes ventricosus
does have a preference over their food consumption and that is they
would prefer to
consume nutrient rich Thalassia testudinum.
