Sea Turtles Introduction Video
Found in many oceans all over the world, green turtles get their name from the green colour of their fat tissue as a result of their diet. The lime and algae they feed on as adults turn the turtle’s fat tissue a greeny colour, and their smooth top shell (or carapace) is also green with brown. The belly shell (or plastron) of the green turtle is a pale yellowy/tan colour. Green turtles can further be identified by a set of 2 scales between their eyes.
Green turtles can grow to 1 metre long and can weigh up to 180 kilograms! As adults, green turtles are herbivores and feed predominantly on algae, but as juveniles they feed on fish eggs, plankton and jellyfish. The gender of adult green turtles is easier to distinguish than the juveniles as males have a long, thick tail as well as an individual mating claw on the fore flipper.
The hawksbill turtle gets its name from its beak-like mouth which it uses to feed on hard and soft sea sponges. Hawksbill turtles are often found on rocky reefs or solid substrates as these are where sea sponges are commonly found.
Female hawksbill turtles can grow up to 87 cm long and will weigh around 80 kilograms at maturity. They tend to nest on both low and high energy beaches. Unusually, their nesting season stretches from 2 months to 6 months which is longer than most other sea turtles.
Hawksbill turtles can further be identified by their 2 claws present on each of their flippers as well as the 2 pairs of prefrontal scales located between their eyes.
