visit the Usa web site 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 degrees C (583) and 17 degrees C (581).  The water depth is around 50-100 meters for turtle 583 and 50-200 m for turtle 581. It is also interesting to note that their rate of travel has lowered to 0.4 km/hr for turtle 583 and 1.1 km/hr for turtle 581.  My guess is that they have found a plentiful forage ground and I also suggest that they both are back in an area they have visited in years past.. Just a guess on my part.  As the water warms, they may move up into the embayments that are now still too cold for them. Dr. Tomomi Saito, Director of Usa Marine Biological Institute, commented:  " The Seto Inland Sea is still too cold to enter, but the water temperature in the southern points of the Kii Peninsula or Shikoku Island...

  Food Items available to loggerhead turtles: Loggerhead turtles (Caretta caretta) living near Baja California, particularly the sub-adult and adult individuals, primarily feed on a wide variety of benthic (bottom-dwelling) invertebrates . Their powerful jaws are well-adapted for crushing hard-shelled prey. Here's a breakdown of their typical diet in this region: Crabs: This is a major component of their diet. They consume various species of crabs found on the seafloor. Clams and Bivalves: Loggerheads are known to dig for and crush clams and other bivalves. Snails and Gastropods: Different types of marine snails are also part of their diet. Sea Urchins: These spiny invertebrates are also prey for loggerheads. Conchs: Larger conchs and other large shelled mollusks are consumed. Other Invertebrates: They may also feed on other bottom-dwelling creatures like worms, sea cucumbers, and various crustaceans. Occasional Fish: While not their primary food source, they may oppor...

  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. Loggerhead turtle 571 has begun to remain in the same vacinity which indicates that she has found an area that provides a bountiful foraging area. 571 has moved a little off shore and may be moving out into the Kuroshio current.  Stay turned to see where she goes! 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...
