Mean (+ s.e) difference in body and anterior temperature between paired upwards and downwards facing limpets.

<p>(a) measured at one point in time (n (combined across locations) = 110 (b) measured during emersion (n (combined across locations) = 12). Difference = temperature of upwards facing limpet–temperature of downwards facing limpet. * = significantly different from 0.</p

Association between heamolymph osmolality and head orientation (differences in orientation from downwards) in <i>Cellana tramoserica</i>.

<p>(a) Patch 1 Time 1 n = 46 (b) Patch 2 Time 1 n = 64 (c) Patch 3 Time 2 n = 89 (d) Patch 4 Time 2 n = 85 Downwards is defined as between 135° and 225°, where 0° was straight up [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0150200#pone.0150200.ref032" target="_blank">32</a>].</p

Comparison of mean (+ s.e) body and anterior temperature of limpets orientated in different directions and different habitats (n (combined across sampling times) = 10).

<p>(a) body temperature (b) anterior temperature. Treatments were control limpets (C) facing downwards, individuals rotated 360° (P) and individuals rotated 180° to face upwards (T) in the shade (grey bars) and sunlight (white bars).</p
