There are species

There are species where the relationship between male and
female is more clearly defined. For instance spiders
where the male role is so marginal that
the femal eats the male
when he has delivered his sperm

And then there are fish
where the male is so tiny that he
lives like a polyp
on his mate

There are species

Der finst arter der forholdet mellom hanndyr og
hodyr er tydelegare. For eksempel edderkoppar
der hannens rolle er så perifer at
hodyret et opp hannen
når han har levert sæden sin

Og så finst der fiskeslag
der hannen er så liten at han
lever som ein polypp
på maken sin
