Odisha Coast: Olive Ridley sea turtles come to Odisha coasts for nesting in large numbers. Hence the activity is termed 'mass nesting' or 'arribada'. Worldwide attention is focused on the conservation of Olive Ridley Sea Turtle in Odisha because about 50% of the total world population of Olive Ridleys, and 90% of the Indian population of sea turtles been coming every year .
Scientific Name : Lepidochelys olivacea
Type : Reptile ,
Distribution: Nesting sites all over the world, on tropical and subtropical beaches
Body Size (adults) : Length 60-70 cm; mass up to 70 kg
Life span in the wild : Average 50 years.
Diet : For all life stages, mostly benthic invertebrates (e.g. crabs of all types, other crustaceans; mollusks) and sometimes jellies
Reproduction : Every 1-3 yr; 1- 3 clutches of eggs per season; 90-130 eggs per clutch; ~30 g grams each (ping-pong ball size); ~ 25 mm in length and weigh 15- 20grams).Once a nest has been completed, the female never returns to it. The eggs and resulting hatchlings are left to fend for themselves and locate the water upon emerging.
incubation period : 45 - 58 days .
incubation period : 45 - 58 days .
Gender : The temperature of the nest determines a hatchling's gender. This is called Temperature-Dependent Sex Determination (TSD). Warmer temperatures produce mostly females, and cooler temperatures produce a majority of males. There is a pivotal temperature that produces an equal ratio of males and females. The temperature determining sex ratio differs between species and nest location.
Threats : Beach erosion, non-human predation, exploitation for meat and eggs, Casuarina plantations & Mechanised fishing Boats (More details) .
Odisha coast favorable for sea turtles : Odisha coast is crises-crossed by estuary, rivers, creeks and creek lets, Land inundated by the saline and sweet water and covered with mangroves, Estuaries are the breeding and spawning grounds fishes, prawns, crabs and mollusks. The river mouth becomes the feeding ground of the sea turtles from October to May , therefore they having migrated over large distances in the sea to feed and nesting.
About 50% of the total world population of Olive Ridleys, and 90% of the Indian population of sea turtles been coming every year . Worldwide attention is needed for conservation of this species.
Nesting period : From October to early summer
Nesting Places of Odisha
Major breeding grounds:- Rushikulya , Dhamra and Devi estuary
Minor breeding grounds:- Mahanadi, Subarnarekha, Budhabalanga, Keluni & Bahuda estuary

How to Help :
01 . Declaring
no fishing zones, imposing seasonal fishing bans, encouraging use of Turtle Excluder Devices.
02. Save Eggs from depredation
by feral animals and humans
03. Prohibition of discharge of crude oil,
pesticides, heavy waters, heavy metals and other poisonous effluents to
estuaries and coastal areas and near turtle nesting beaches.
04 . Prohibition of discarding of fishing
nets, plastic bags other trash into the water or on the
beach which results in ghost fishing and incidental mortality of
sea turtles.
05. Aware the local communities ,Students , Govt
& Non -Govt people to clean up the nesting beach and educate people about marine turtles
