Red Tide

From the album Invertebrates

The Pelagic Red Crab, also known as the Tuna Crab, is not a normal visitor to Southern California. They are at the mercy of ocean tides and unfortunately, these small members of the squat lobster family sometimes will wash up en masse on local beaches.

Needless to say some folks are displeased than others, especially those in charge of cleaning up the mess!
