For the many other marine species yet to be assessed that are
dependent on or associated with seagrasses, the newly available
seagrass species Red List assessments will provide critical information.
Effects on other species at risk are exemplified by the link between
seagrasses and their direct grazers including sirenia and
turtles; e.g., in Placencia Lagoon, Belize the Vulnerable seagrass
H. baillonii is a major food source for the Vulnerable manatee
(Trichechus manatus), while the Vulnerable seagrass H. hawaiiana,
endemic to the Hawaiian Islands, is fed on by the Endangered
green turtle (Chelonia mydas).
