Figure 1 in How survival and food intake of tri-spine horseshoe crabsı Tachypleus tridentatus respond to thermal variation: implications for understanding its distribution limit

Figure 1. Global distribution of T. tridentatus as reported by previous literature, and the regional changes of sea surface temperature (SST) in (a) summer and (b) winter. Note the three occurrence reports outside their geographic range: (1) a non-native population from Chubu Region, Central Japan; (2) an escape population from Okinawa Prefecture, Japan due to broken nets during transportation; (3) a sighting of single female from Jeju, South Korea, which was not associated with a known spawning or juvenile nursery habitat.
