|Hermit crab trails, Willow Point beach|
The hermit runs forward, instead of sideways like his cousins, the crabs. He leads with his big left pincer, then follows with the small right pincer and two larg(ish) legs on either side. Depending on the shell he's chosen, he either drags it behind, leaving a deep valley down the centre of his track, or carries it above ground level, so that his several rows of footprints aren't erased.
In the photo above, the smaller hermit, who left his trail top to bottom more or less down the centre line, was carrying a draggy shell, probably one of the long, pointy Asian mud snail shells. A larger hermit carrying his shell high, barely touching the sand, crossed right to left, corner to corner.
