Euchaetidae is a family of marine copepods. [1] The family is cosmopolitan and occurs in all the oceans, including the Southern and Arctic Oceans. [2] [3] Euchaetidae are medium to large-sized copepods. [4]
There are two genera with in total 114 species: [1]
- Euchaeta Philippi, 1843 – 16 species
- Paraeuchaeta Scott, 1909 – 98 species
Euchaeta are mostly epipelagic whereas Paraeuchaeta are mostly bathypelagic. [2] Where more than one species occurs, congeneric species (or life stages of a single species, as observed for Paraeuchaeta antarctica) may partition the water column, whereas species representing different genera that occur at similar depths differ in dietary preferences. [3]
Paraeuchaeta can be important predators of fish larvae. Their mode of predation is " drift and wait". The dominant euchaetid in the Southern Ocean is Paraeuchaeta antarctica. It is a dominant predator there, and its fatty acid profile suggests that it mostly preys upon herbivorous calanid copepods. In the Weddell Sea, it contributes as much as 11–18% to total mesozooplankton biomass. [3]
Paraeuchaeta antarctica has a one-year life-cycle around the Kerguelen Islands. [3]
