Another period of intensive growth occurs in spring before breeding. I. baltica is the dominant species in both habitats examined. I. chelipes and I. granulosa were found not to coexist.

Allozyme variability was examined using starch-gel electrophoresis between sub-populations of Idotea chelipes over a small geographic distance (approx.

For example, Idotea pelagica is found in the lower intertidal and shallow subtidal on exposed rocky reefs and is replaced in less exposed areas by I. granulosa which in turn is replaced by I. chelipes on sheltered, estuarine shores (Naylor, 1955). Life history Adult characteristics.

Idotea chelipes föredrar strandkanten, där vattnet är lugnare och varmare, medan I. granulosa gärna vill ha det mer turbulent i mer öppna kustavsnitt. Ofta hittar man I. balthica tillsammans med en av de andra arterna, men på vissa platser finns även alla tre arterna tillsammans då de sannolikt konkurrerar om mat och plats.
