Marine Aquarium team releases babies into the ocean
Paradise Island, Bahamas -
The Sun had barely dipped below the horizon on
Paradise Beach as half a dozen everyday citizens joined members of
Atlantis’ Marine Aquarium Operations team for a unique and beautiful
experience. They gathered roughly 500 yards west of The Reef, to release
about 20 baby green turtles onto the sand to begin their life journey
in the Atlantic Ocean. Without any coercion or direction, the hatchlings
waddled down the dunes into the ocean and disappeared in the darkness.
Mature female Green Sea Turtles (
Chelonia mydas)
lay an average of 300 to 600 eggs every nesting season which occurs
roughly every two years. The females may come up an average of 2- 3
times per season to dig and deposit clutches of eggs. At Atlantis, a
turtle nesting beach adjacent to the turtle lagoon at Beach Tower
provides the perfect habitat for the gravid females to deposit their
eggs. Because the beach is too small for multiple nests, the Aquarium
team has to check the beach each morning during the nesting period
(typically May thru July), looking for turtle tracks and a disturbed
area of sand left by the female the night before so that the nests can
be easily located and the eggs can be carefully excavated.

Once the eggs are unearthed, they are removed
from the nest and individually marked to ensure proper orientation. They
are then transported to the fish hospital to be counted and incubated
in replica of the nest. For the next 60 days or more, the husbandry
team meticulously cares for the incubating eggs by maintaining optimum
conditions in the incubators for the future hatchlings. A temperature
reading is taken at the nesting site and heat lamps over the incubators
in the hospital help maintain the temperatures as close as possible to
that of the original nest. This year, Atlantis’ green turtles have laid
approximately 900 eggs but not all of them may be fertile.
According to Sr. Aquarist Elgin Hepburn, should
only a fraction of those eggs hatch, there would too many turtles to
care for considering this year the team has incubated over 900 eggs.
“Releasing them to the wild is the best option
and a good way to add to the wild population. When the baby turtles,
called hatchlings, emerge from the sand in the incubator, we schedule a
release within one to two days, depending upon the size of their
remaining yolk sack,” said Hepburn.
“It is important to release the turtles soon
after they hatch so that they are able to adapt quickly to the natural
environment and do what their instincts tell them to do. During the
actual release, the little hatchlings are taken to a beach in the late
evening as the sun is about to set because this is when they would
naturally emerge from their nests. They are placed on the sand and
allowed to crawl to the ocean. This is important because it is believed
that mature female turtles may return to the same beach from which they
initially entered the ocean.”
“As a team, we in the Marine Aquarium Operations
department are very proud and extremely grateful that we have this
opportunity to contribute, in a small way, to the population numbers of
turtles in the wild,” continued Hepburn. “Many turtle species are either
threatened or endangered, so it is a commendable that Kerzner
International's management team allows us to maintain a breeding
population of Green Turtles and release the hatchlings. By having such
releases, it is our hope that we are playing our part as a good
corporate citizen to ensure that Green Turtles will exist in the waters
of the Bahamas for years to come.”
