  • all 7 species of sea turtles nest on beaches; females lay up to 7 clutches at 10 - 14 d intervals. interbrood interval 2 - 8 yrs; males might return each yr. Feeding starts 5-11 d after hatching (ref: Jone2009)
  • feeds on gelatinous zooplankton, mostly jellyfish: Aurelia, Chrysaora, Cyanea, Rhizostoma, Stomolophus (ref: Wiki)


  • Jone2009: 1.3e11 g jellyfish converts to 2.6e13 J, so jellyfish have 200 J/g
