Spearer mantis shrimp
Harpiosquilla sp.
Family Squillidae
updated Oct 13
Where seen? This energetic shrimp-like animal is often seen on our Northern shores, especially among seagrasses. It is more active at night.

Features: 6-10cm long. Body broad and long, colour plain grey or beige with fine dark bars and lines. Broad tail that have spiky edges and a pair of paddle-shaped appendages. Some have colourfully marked tails.

The huge front pincers resemble those of the Praying mantis insect or the blade of a pocket knife that folds into the handle. Armed with sharp spines, the pincers extend and retract much faster than an eye blink and the sharp spines impale soft, fast-moving prey like fish and prawns.

Status and threats: Our mantis shrimps are not listed as endangered. However, like other creatures of the intertidal zone, they are affected by human activities such as reclamation and pollution.
