8 cm – 30 cm

Diet

Carnivore

Feeds mainly on other animals.

Social structure

Colony

Lives in large concentrations, often for breeding reasons.

Fun facts

  • Its mouth unfolds into a tube almost as long as its head to suck in copepods with millimetre precision.
  • Its populations in the north-eastern Atlantic have multiplied spectacularly since the 1990s, a change linked to warming water that has made it one of the most abundant fish off western Ireland.
  • Its mouth is extremely protrusible: it projects it forwards like a tube to suck in zooplankton, hence its pointed-snout profile.
  • Its populations have exploded in the north-east Atlantic since the 1990s, an increase attributed to warming waters. It has gone from a marginal species to one of the most abundant on the European continental slope.
  • That sudden abundance opened up an industrial fishery targeting it for fishmeal, above all in Irish waters.
  • Its body is deep, strongly compressed and an intense orange-red, with large eyes adapted to the dim light of the continental slope.
