 The adult leatherback sea turtles weigh 2000 pounds.
 The babies weigh around 45 grams.
 The adults are 6 foot 5 inches long.

 There are 34,000 nesting females.
 They eat jellyfish, fish, and algae.
 Their shell is black with pinkish white dots.
 They are found in warmer oceans.
 They are on the top of the food chain.
The leatherback sea turtles
population is decreasing as listed
below
Reasons for decrease
There are many factors why the leatherback sea turtles
are endangered.
The main abiotic factors are:
 They mistake plastic bags.
 People poach the eggs and the flesh of the leatherback
sea turtle.
 They get caught in commercial fishing nets.
 And loss of their habitats in remote stretches of sandy
beaches.
Biotic factors
 Humans
 They eat the leatherback sea turtles
 They poach the leatherback sea turtles and their eggs
Abiotic factors
 Plastic and plastic bags
 They mistake plastic for jellyfish and choke and die
 Habitat destruction
 Loss of habitat
 No place for the leatherback sea turtle to nest
 Nets
 The leatherback sea turtles can caught inside of them

Conservation methods
 Some people invented a TED ( Turtle Excluder devices)
It allows fisherman to still catch the fish but also if a
turtle gets stuck they can go through a little hole.
 There are a few other conservation ideas and groups
that are looking for donated money to get started.
 These methods helped to increase the population of
leatherback sea turtles. Which will then help fisheries
etc.
Why is this important?????
 It is important to save the leatherback sea turtle
because they don’t do anything to humans we just kill
them
 They help swimmers not to get stung by poisonous
jellyfish and make them go to the hospital or
something like that
How do the leatherback sea turtles
affect us
 They do not harm people
 They eat jellyfish which eat good fish from fisheries
 They are the largest reptiles on the earth
They need your help,
OR ELSE
They will join all of the other unlucky animals who
got extinct.
Don’t let this happen,
Save the Leatherback sea turtle!!!!
