Table 1. Caretta caretta. Details of each female’s size, behaviour and habitat utilisation during internesting and post-breeding periods. CCL: curved carapace length. CF:
clutch frequency. Water depth: average depth of water inhabited during internesting period; it includes positive values, as the daily-interpolated locations were obtained
from turtles in near-shore habitat around a peninsula. Av. displ.: average displacement from initial tagging location. Values are means ±SD, ranges in parentheses. Datadays:
number of days with data from total number of days during the period (percentage in parentheses). Oceanic days: number of data-days spent in water depths >200 m
from data-days (percentage in parentheses). Post-nesting data include migration and foraging periods. Max. displ.: maximum displacement from initial nesting location.
Values for countries are the number of data-days the turtle spent within the country’s territory (percentage in parentheses). Turtle I remigrated to Masirah to nest after
a single year, hence the data is divided into first (P1) and second (P2) post-nesting periods

a Transmitter ceased functioning before final foraging location was identified.
b Transmitter temporarily ceased functioning on 27 July 2006, thus possibly missing a 6th
nest, restarted when turtle was far from the island on 12 September. c Transmitter temporarily ceased functioning on 27 June 2006, thus missing possible subsequent
nests until the transmitter resumed functioning far away from the island on 5 September 2006. d Turtle moved away from the island and returned again, finally departing
on 12 August; however, timing and locations do not indicate the turtle renested after 12 July
