Altered developmental timing in early life stages of Antarctic krill (Euphausia superba) exposed to p,p′-DDE

► Short term p,p′-DDE exposure stimulates development in Antarctic krill. ► Delayed effects include mortality and inhibition of metamorphosis. ► Developmental effects occur at body burdens ten times lower than behavioural effects. ► Antarctic krill larvae are at least as sensitive to p,p′-DDE as temperate species. ► First POP threshold data for developmental toxicity in Antarctic krill.
