Rejer

Rejer er svømmende krebsdyr med langt, smalt muskuløst underliv og lange antenner.

Nordlige rejer (Pandalus borealis) er en subarktisk art, udbredt i de nordlige dele af Nordatlanten og det nordlige Stillehav.

Rejer har en bemærkelsesværdig livscyklus. Ved seksuel modning bliver den først hankøn, men skifter senere køn og bliver hunkøn. Dette sker i en alder af 2-6 år i forskellige farvande, afhængigt af miljømæssige forhold (for det meste hav-temperatur).

Rejer har høje niveauer af omega-3 fedtsyrer og lave niveauer af kviksølv. Som andre skaldyr, har rejer et højt indhold af calcium, jod og protein, men lavt indhold af kulhydrater.
