The Life Cycle of a Green Sea Turtle is a fascinating glimpse into the major growth phases of this reptile.
Green sea turtle eggs are buried in clutches of 75-200. After two months, the hatchlings make a mad dash for water, where they’ll spend the rest of their lives. Green sea turtles don’t reach adulthood for 10 years or more, but they can live up to 100 years.
Scientific Name: Chelonia mydas
Characteristics: Green sea turtles get their name not from their shells, but from their subdermal body fat. Unlike many other turtles, they cannot retract into their shells.
Size and Color: Although these figures are dark green, sea turtles can also be brown, grey, or olive. The adult figure is approx. 7 cm long. All of our products are Non-toxic and BPA free.
The Life Cycle of the Hawaiian Green Turtle (Chelonia mydas) – Reproduction
Female green turtles emerge at night to deposit eggs, the process taking an average of two hours. Up to seven clutches are deposited at 12 to 14 day intervals, but the average is probably two or three clutches. Accurate counts of the number of clutches per season are difficult to get. The average clutch size is 100-110 eggs.
It is uncommon for females to produce clutches in successive years. Usually 2, 3, 4 or more years intervene between breeding seasons. Mating occurs in the water off the nesting beaches. Little is known about the reproductive biology of males, but evidence is accumulating that males migrate to the nesting beach every year.
One interesting discovery in recent years is that incubation temperatures determine the sex of hatchling turtles. In 1985, Standora and Spotila reported this effect on green turtles. Eggs incubated below a pivotal temperature–which might vary among populations–produce primarily males, and eggs incubated above this temperature produce primarily females.
