I know that turtles live long.

This lesson is about Sea Turtles which are different from Tortoise that we see in a zoo or a reptile park. There are seven species of sea turtles -out of which five are seen in India – the Olive Ridley, the Hawksbill, the Green Sea Turtle, the Loggerhead and the Leatherback. The turtles are huge and weigh between 35 kg and 700 kg. The largest sea turtle is the Leatherback which is 2.2m long and 700 kg in weight. Sea turtles come to the shore to lay their eggs. Except Olive Ridleys, other species have become rare in India. Mass Nesting or Arribada is a phenomenon that occurs in Odisha and other two places in the world where Olive Ridleys come ashore alone to lay their eggs.

Between January and March, female Olive Ridleys come ashore and haul (pull with force) using their front flippers onto the beach. They choose a spot away from the high tide and dig 45 cm into which they lay their eggs. They lay about 100 eggs at one time. After covering the nest with sand it returns to the sea. The eggs are left to incubate under the sun. People collect these eggs for eating. Jackals, domestic dogs and pigs eat the eggs. After escaping from the predators, the hatchlings (little ones) come out the egg shell with the help of egg-tooth. After they come out they make a dash into the sea.

Weighing less than 20 grams, many of these hatchlings fall prey to crabs or birds before they reach the sea. It is estimated that one in a thousand hatchlings become an adult. After swimming for years in the sea, the adult female returns to the same beach where they were born which is an unsolved mystery. Human activities have endangered the survival of sea turtles. Problems like pollution, dumping of plastics in to the ocean and the construction activities on nesting beaches endanger their survival. We have to tackle these problems to save the sea turtles.

People hunt the sea turtles for their meat. They collect their eggs. Some times the turtles are trapped in the nets of motorboats. Pollution and dumping of plastics into the ocean affect their survival. Construction activities on nestling beaches also hurt their survival.

Only by systematically tackling the problems faced by the sea turtles and removing the threats subjected to them, can we ensure that sea turtles will continue to exist in the years to come.

The Oliver Ridley, the Hawksbill, the Green sea turtle, the Loggerhead and the Leatherback.

(a) endangered

Ammamma asked the children to sit upstairs in the middle room and gave. The Reptiles spend almost their entire life in the sea.

Mass nesting takes place on the shore. Odisha is one of the only three places in the world, where a phenomenon known as mass nesting or Arribada takes place. Thousands of female turtles come ashore simultaneously to lay their eggs on particular beaches.

When most of the eggs have hatched, the hatchlings push themselves upwards through the sand and emerge on the surface of the beach. From there, they make a hurried dash to the sea.

(b) to systematically tackle the problems and removing threats

Correct answer is (a) swim

1. c 

2. d 

3. b 

4. a

(a) egg-tooth

Correct answer is (b) 1000

Swimming – I like swimming 

Motorboat – We went on a motorboat 

Crabs – People eat crabs as sea food 

Sand – Children play on sand 

Cavity – There are cavities in beach

(b) return to the same beach to lay their eggs

There are many sea animals in the ocean. They are beautiful and wonderful in varied sizes, shape and structure. The fishes are in different colours and are of different varieties. Many rare species of fishes are found in deep sea. Most corals and exotic species are under the sea.

They must come ashore to lay their eggs.

1. Female Olive Ridleys come ashore at night to lay eggs. (✓) 

2. The eggs of an Olive Ridley are in the shape and size of a cricket ball. (×) 

3. Ridleys come to lay their eggs in the month of January. (✓)

4. The turtles use their flippers and make a hollow for their nests. (✓) 

5. The hatchlings use a tiny egg-tooth to come out of the eggs. (✓)

After many years of swimming in the open ocean, the female hatchlings that have become adults return to the same beach, they were bom. They come there to lay their own eggs. How they manage to find the place after so many years in the sea is one of the many mysteries of these fascinating reptiles. It is also a wonder that they have survived natural dangers for millions of years.

(a) they find it difficult to walk on sand

(b) incubate eggs in the warmth of the sun

(b) lay eggs

It weighs up to 35kg, when fully grown

The eggs that escape from the people and predators hatch 45 – 60 days later. The hatchlings slash open the leathery eggshell with the help of a tiny egg – tooth.

There are seven species of marine or sea turtles in the world.

Jackals, domestic dogs and pigs dig up and eat the eggs by following the scent left by the turtle. Even the local people follow the tracks of the turtle to its nest and collect the eggs for eating.

(b) sea turtles

I think that the shells of the turtles are like leather and hawksbill.
