Upon arrival, Shara did not have any obvious external injuries so we did some imaging to get a better idea of her condition. Her X-rays showed signs of drowning and pneumonia (a secondary lung infection). They also showed an abnormal accumulation of material in her stomach and excessive gas build up in her lower intestinal tract, which is preventing her from diving.
Her blood work however is not critical although she has an infection, which we will treat her for. She is currently receiving fluid therapy, antibiotics, analgesia and multivitamins. We will soon be performing further diagnostics pending on her progress in the next few days.

Shara was started on therapy and pain relieve and after some days she passed different types of plastic in her faeces (from styrofoam to rubber). After that, she started feeling better and began eating. She has now a voracious appetite and is much brighter. However, she is still buoyant and thus we are starting her on an adapted feeding scheme to motivate her to dive down since she is very food orientated.
12 March 2023
Shara has been diving down for her food although not very graciously yet. We started her on a weight therapy this past week to promote a more physiological body position and hopefully help her improve her diving abilities. The injuries on her flippers are much improved and she is now off all medications as well.

Shara has been improving her diving skills! The Targeted External Weight Therapy she has been on for the past weeks has really been helping her to adapt to a more physiological position in the water and to rewire her brain as to how diving works. Given she has a voracious appetite we use feeding sessions to train her diving abilities.
1 May 2023
Shara has been responding really well to the targeted external weight therapy we placed on her last month. She no longer requires a lateral weight as she has learned how to stay central in the water and has been improving her diving skills. Shara is now able to spend most of her day submerged!
13 June 2023
Shara is now in the final stages of rehab! She has finished all therapies, has been resting at the bottom without any assistance and swimming happily around her tank with no difficulty. Her last set of blood work and X-rays were also clear, so we are just giving her enough time to ensure that her behavioural issues are completely sorted before we release her back into the ocean.
29 June 2023
Shara had her last round of blood work and X-rays today. All exams returned normal and since her buoyancy control has been perfect she has been deemed fit for release! Shara will be our first turtle of the year to be fitted with a satellite track, and with her we will be resuming our ORPTrack initiative. We are very excited to follow her journey once she’s back in the ocean.
1 July 2023
Shara was our first turtle of the year to be fitted with a satellite tracker. This will allow us to follow her movements as she travels through the Indian Ocean. Tagged and ready, Shara was released from the beach at Coco Palm Dhuni Kolhu.
19 July 2023
Shara wasted no time leaving Baa Atoll and the Maldives! Since her release, she has made great strides straight east into the Indian Ocean. Based on the data that has come back, it does not appear that Shara has had any periods where she is simply foraging or searching for food; it really does look like she has places to be and is heading straight for them.
31 August 2023
Shara has been travelling for 57 days now, continuing in an eastward direction. She made a brief stop in the Laccadive Sea where she was seen circling for a while at a much slower speed, and was even diving quite a bit. A conservative conclusion could be that she was spending some time foraging in that area. Once she was done there, she continued her travels east and northeast around the coast of Sri Lanka and towards the Bay of Bengal. A previous genetic study has shown that a large portion of the olive ridleys we find entangled in the Maldives belong to the nesting population along the coast of India. Maybe Shara is heading back there?
By now, Shara has travelled 1,861 km, covering about 32 km per day since her release. Her average speed was recorded at 1.36 km/hr. Shara continues to dive between stretches of swimming in shallow water, spending most of her time above 40 m, with several more dives down to 300 m.
24th September 2023
Shara has now covered a total distance of 2367 kms and travelled all the way to the Bay of Bengal, where she seems to have slowed down. We are conducting further analysis to understand if this indicates that she has arrived in a foraging area.
