Comprehension

A. 1.

A conservationist had found a dead Olive

Ridley sea turtle washed ashore on a beach in

Chennai many years ago, and she had decided

to do something about it. She and her friends

decided to educate the fisher folk and people

living along the coast about sea turtles and the

need to protect them. This was how the turtle

walk started.

2.

We were given two tasks—

to look for turtle eggs and to release newly-

hatched turtles into the sea. The volunteers

were asked to look out for marks like tractor-

tyres leading from the sea towards the shore.

3.

Noufiya found the nest of the turtle by

following its track along the sand. The tracks

are created by the flippers of the female

turtle as she drags herself across the sand.

4.

A volunteer spread some sand in a basket and

transferred the eggs to it. He covered it with

more sand from the nest. Another volunteer

wrote down the date, time, number of eggs and

temperature of the sand on a piece of paper and

put it in the basket. Two others then took the

basket to the hatchery.

5.

After returning to

the hatchery, Noufiya dug three separate holes

in the sand and buried the turtle eggs in these

nests. Sand from the original nests was also

used for this. In another part of the hatchery,

she saw hundreds of newborn Olive Ridley sea

turtles, hatched from the eggs collected almost

two months ago. She even got to hold one in

her palm.

6.

The hatchlings were taken

in baskets towards the sea. The volunteers

formed a semicircle on the beach and put 241

hatchlings on the ground. At midnight, the

newborns walked into the sea. Some of them

were washed back to the shore. The volunteers

directed them towards the sea, and soon,

all the baby turtles disappeared from sight.

7.

Adult Olive Ridley turtles are killed for their

skin or meat. They often get trapped in fishing

nets and their flippers get cut off. Most of

them are severely wounded and they drown.

Turtle eggs and hatchlings are eaten by crabs,

dogs, snakes, birds or are trampled on by

people. Hatchlings instinctively walk to the

sea, guided by the starlight reflected by the

waves. But the street lights confuse them and

they walk towards the shore. Their chances of

survival on land are very slim. They have also

become endangered because there are very

few nesting sites remaining in the world for

these turtles.

8.

Olive Ridleys are so called

because of the colour of their heart-shaped

shell and H N Ridley, who discovered the

species.

B. 1.

NT. The turtle walk is organised to protect

the sea turtles and to educate the fisherfolk

and people living along the coast about sea

turtles.

4.

NT. There are

very few nesting sites remaining in the world

and so

arribadas

occur in very few places.

6.

NT. One female Olive Ridley turtle

lays about 80–120 eggs.

C. 1.

Turtle walks help to spread awareness about

the population, nesting habits and dangers to

Olive Ridley sea turtles. Such walks reinforce

in us the need to protect endangered species

like the Olive Ridley. They also teach volunteers

to take care of the eggs of these turtles and

how the hatchlings must be protected until

they reach the sea. In this way, they help in the

conservation of these turtles.

2.

Arribadas

take place only at night because the beaches

are usually filled with people during the day

and the turtles find it safer to lay their eggs at

night when the beach is relatively empty.
