visit the Usa web site 7/18/2025 A new capture and note from Dr. Tomomi Saito ( Usa Marine Biological Institute ): "We are pleased to report that we relealsed a female loggerhead turtle fitted with a transmitter today from Kochi Beach (33°27'59.2"N 133°29'48.5"E). By the way, while patrolling Kochi Beach this morning, we discovered this female got caught in a wave dissipating block and was unable to lay eggs. We released her today, so we hope she will lay eggs from tomorrow onwards." Turtle specific data: 17/7/2025 discovered at Kochi Beach SCL: 87.8 cm, SCW: 68.5 cm, BM: 84 kg Left hindlimb tag: 56189; right: 56188 PTT Transmitter ID: 286997 PIT Tag ID: 392145000243138 Below are some pictures from the Usa team of the loggerhead: Kochi female loggerhead shortly after capture on Kochi Beach. Kochi female loggerhead after the Spot 6 satellite tag was attached. Headed back to the water after a successful tag attachment.  We are hoping to be able to track her m...

  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...

Link to current trajectory map of #203 and #204 3/27/2024 Turtle 204 continues to transmit locations very reliably.  It has been transmitting for 208 days now and has traveled roughly 8000 km.  Given that 208 days represents 4992 hours, 204 has been traveling/swimming at a rate of approximately 1.6 km/hour.  Below is a short animation of the water currents and 204's track indicating where 204 is as of March 27, 2024.   2/29/2024 Turtle 203 stopped transmitting on 2/3/24 but 204 continues to transmit.  Below is the current location of 204.  It appears that 204 is riding around in a small current eddy that has branched off of the main Kuroshio current.  These eddys tend to concentrate food items and are know to be areas preferred by loggerheads.   Above is an animation of the travels of #204 in the Eddy shown above from 1/13/24 to 2/29/24.   2/2/2024 Here is an animation of  203's and 204's trajectories after their release i...
