Discussion
- Jone2009: 1.3e11 g jellyfish converts to 2.6e13 J, so jellyfish have 200 J/g
- mod_1: data on ingestion/metam revised, tJO_e, Ww0, Wdb data added
- mod_1: pAm was ignorned because of inconsistency with other data and because allometric correction was applied for obtaining the specific rate
- mod_1: Ww0 was ignorned because it needs detailed modelling of the contribution of water to weight
Facts
- 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)
