Behavior
Instead of just looking at the complicated looking graph or something, why don't we just look at the simple world map??
Habitat
Leatherback
Olive Ridley
Kemp's Ridley
Hawks Bill
Loggerhead
Hawksbills
:carnivore/ usually eat sponges that have razor-sharp glass skeletons and jellyfish which are really poisonous to humans
Olive and Kemp's Ridleys
: carnivore/ usually eat spiky urchins and lots of jellyfish which are really dangerous for humans
Green
: herbivores (not fully grown sea turtles are omnivores)/ mainly eats sea grasses which makes them herbivores
Loggerheads
: carnivore (not fully grown sea turtles are omnivores)/ eats crab, queen conches, and oysters
Leatherbacks
: carnivore/ eats jellyfish-like creatures called Portuguese-man-of-war that has ridiculously painful sting affecting humans, but not sea turtles
What they eat...
How do they eat poisonous jellyfish and crabs?
jagged stalactites in turtle's mouth
Most of you might think that turtles might die when they eat poisonous jellyfish or something. However, they don't die because of their weird-looking teeth called "jagged stalactites" in their mouth. This thing helps turtles to digest some poisonous sea animals which means that it helps them to be protected from poison or sting. Leatherback and Loggerhead crave this since their main food they eat is jellyfish. It's actually a really important protection!!
Other ways of eating Crabs, Jellyfish, etc
If loggerheads were able to gobble jellyfish, they were able to poke around the coral reef and rocky areas to find for crabs and oysters. When they do find it, they use their powerful jaws to crush the shells.

the life cycle of sea turtles
Facts about Reproduction (mainly about the nesting)
female digs a nest by scooping sand with their back flippers
female can lay 80-120 eggs which is pretty amazing
when the eggs are laid, they are the size of a ping-pong ball
after 60
days, the baby sea turtles called hatchlings destroys their eggs and come out.
if the egg is around 28*c, the
hatchling would be a
male and
if the egg is around
29.5*c, the hatchling
would be a female
we are friends, right dude?
