Dr. Saito (Usa Marine Biological Institute, Kochi University & PI) wrote:  " ID581 is hanging around at the eastern entrance of the Seto Inland Sea.  Nearby, in the largest loggerhead nesting site in Honshu, Senrihama-Beach in Minabe Town, Wakayama Prefecture, nesting was confirmed for the first time this year last weekend." Below is a video of their tracks/movements since late March up through 5/25/2025. 4/27/2025 Below is a video clip of turtles 581 and 583 showing their travels since they have arrived in shallow waters.  Their track is overlayed on sea surface temperature to show that they are in waters that are 15-16 degr...

  AUGUST 8, 2024 POST NESTING LOGGERHEAD SATELLITE TAGGED  KOCHI BEACH, JAPAN The post-nesting loggerhead is now meandering around an area that appears to be very favorable for her.

Above is an image of loggerhead #571 nesting on Kochi Beach taken by Noah Yamaguchi with a drone mounted IR camera at 0200 hours on August 6,2024.  A team from Usa Marine Biological Institute was able to capture her after she finished laying eggs. 571's eggs (110 in number) were retrieved and placed in the protected hatchery on Kochi Beach.  If these eggs hatch successfully, they will constitute the fourth cohort of STRETCH turtles scheduled for release in 2026!   Post nesting loggerhead turtle #571's locations an...
