Tiny spider crab
awaiting identification*

Where seen? All kinds of tiny spider crabs can be seen on many of our shores, hidden among seagrasses and seaweeds. They require a very keen eye indeed to spot.

Features: Body width 0.5cm or less. Body teardrop-shaped or triangular. The body and spindly walking legs often covered with filaments to which tiny bits of rubbish or delicate algae are stuck. Pincers short and tiny. Slow moving.
