Figure 1. (a) The Arabian Peninsula, with Barr Al Hikman in the red square. (b) Barr Al Hikman. The red square indicates the boundaries of the map given in c. (c). Bathymetry map showing part of the intertidal mudflats of Barr Al Hikman, based on Bom et al. (2020). The locations of burrow excavation and the shore profile are also given. (c) Shore profile (tidal height) as a function of distance to the coast at the sampling locations (see d). The sampling locations and the zone in which Macrophthalmus depressus and M. sulcatus can be found are indicated (see Bom et al. (2020) for a detailed distribution map of M. sulcatus). The high and low tide waterlines for both spring tides and neap tides are also given. They correspond with the highest high tide during spring tide and the lowest high tide, highest low tide and lowest low tide in November 2012.
