Narwal Shrimp

In Dive.Explo360: Mediterranean · Northeast Atlantic · Atlantic Ocean · Red Sea · Indian Ocean · Pacific Ocean

In a cave or beneath an overhang, narwal shrimp sometimes form clouds of intertwined antennae. Their pinkish-orange colour and long, spear-shaped rostrum catch the eye. Mainly active at night, they help maintain the balance of the seabed by recycling organic matter.

WHAT DOES IT LOOK LIKE?

The narwal shrimp is slender and elongated, pinkish to orange in colour, often marked with paler lines along its body. It has long, slender legs and, above all, a very long, toothed rostrum resembling a little spear. Its particularly long antennae are always moving and help it sense its surroundings. Like all crustaceans, it grows by regularly replacing its shell during moults.

WHERE DOES IT LIVE?

It mainly lives in deep water, on rocky, muddy or sandy seabeds. It is often found in dark areas such as caves, overhangs or drop-offs, generally from several tens of metres deep.

WHAT DOES IT EAT?

The narwal shrimp feeds on small organisms and organic particles. It captures small prey and also consumes debris, making it an opportunistic species that contributes to recycling organic matter.
