28/08/12 Turtle Dives
Each Wednesday,
we get to abandon our coral and fish survey dives and go on turtle behavior dives
in Baie Ternay. These dives involve getting dropped off at a specific spot in
the bay and cruising around looking for turtles, using a U-shaped navigation
course. If you are lucky enough to see a turtle, you follow it without getting
too close, and take notes on all of its behaviors. Is it eating something? What
did it eat? Did it go up to the surface for air? Is it swimming around the
reef? You also have to identify it as either
a hawksbill or green turtle.
Hawksbill
turtles have a carapace with a jagged edge and green turtles have a smooth
edged carapace. A carapace is the turtle’s shell, for those of you not familiar
with such scientific terms. The green
turtles usually have a cleaner shell, whereas the hawksbill is often covered
with algae. The information collected on
these turtle dives is used compared the frequency of sightings to previous
phases and to create a overall picture of the turtle health and abundance here
in Seychelles. After following it the
turtle for a while, snapping photos and observing the graceful creature, it
usually disappears into the blue, hopefully to be seen again the next week on
another turtle dive.
