Hawksbill and

Green Sea Turtles

The 60km of beach in the Rio Lagartos Bio-Reserve is one

of the three most important

nesting sites for Hawksbill

and Green Sea Turtles worldwide.

The turtle photographs(unless noted)

 are by Santiago Manzanilla Castro,a field biologist,who was working for CONANP,and has studied turtles in the Rio Lagartos Reserve and on Arreceife

Alacranes for 3 years.

Santiago was responsible for a 22 km section of beach during the nesting season that begins in mid April and continues into

November.The number of nests along this stretch of

beach can vary from 800-1500 depending on the number of returning turtles.

Nightly from 9.00 til early morning,the work involves

recording the arrival of the turtles,tagging

recording the location of new nests,egg counts

and after about 2

months a count of hatchlings.

The females will lay from 80 to 150 eggs on average(with

a maximum of 250 recorded)in nests dug about 1 meter

deep in the sand and then covered and mounded with

sand.The optimum hatch is nearly 90% with all conditions

perfect.Interestingly, the sex of the hatchings is  determined by the

temperature conditions of the

season.The warmer the season the

 greater % of females.

The average Green turtle measures

1.15m and weighs 100kg ,the largest measure about 1.5m and weigh 200kg

The average Hawksbill is 90cm and weighs 70kg.The largest measure 1.15 and weigh 100kg.

Loggerheads and Leatherback turtles (up to 2m) are occasional visitors.
