Dreifing tegundar eftir dýpi, seltu og sjávarhita, innan þess breytileika sem allar sýnatökustöðvar ná yfir, sýnt sem heildarspönn lóðréttra ása. Gögn úr botndýraverkefninu „BIOICE“. (ENGLISH – Occurrence zone of the species within the range of water depth, temperature, and salinity, spanned by the "Bioice" samples; demarcated by respective y-axes.) – Ljósm. Guðmundur Guðmundsson

Hæð stöpla svarar til fjölda sýna þar sem tegundin er: fágæt (1-2 eintök); sjaldgæf (3-8 eintök); alltíð (9-32 eintök); algeng (>32 eintök). Gögn úr botndýraverkefninu (Bioice). (ENGLISH- Column height represents number of samples in bins where the species is: rare (1-2 specimens); occasional (3-8 specimens); common (9-32 specimens); and abundant (>32 specimens.)
