  STUDYING THE AFFECT OF ATTACHED SATELLITE TAGS ON THE GROWTH OF JUVENILE LOGGERHEAD TURTLES    A concern that exists regarding the attachment satellite tags to the carapace of a hard shelled sea turtle is how that attachment would affect the growth of scutes under the tag.  There is little to no evidence regarding the effect of these tags because very few of them are ever recovered in order to see if there was any impact on the growth. In addition, when a turtle with a satellite tag stops transmitting (and the battery is still good), we don't know if it was because the turtle was predated, died from some other cause of if the tag "fell" off?    How hard shelled sea turtles grow:  The internal structure of the carapace (the dorsal covering of the turtle) is made of approximately 50-60 bones including the turtle's ribs and vertebrae, which are fused together. These bones grow primarily at their edges along "suture lines," which are zip-zagging sea...

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...
