MARINE

WATER FLEAS

Podon & Evadne

the development of their young

     
In contrast to the many species in fresh water, in the marine environment we find only 5 species. Common in British waters is Podon polyphemoides. The set of images on the left shows the development of the young in the brood pouch on the back. Podon is recognisable by its large compound eye.

Another species of marine waterflea that can often be found flourishing in the spring is Evadne Nordmanni. The image below shows an individual with a winter egg. Evadne has a more elongated body shape and a distinct spine at its rear end.

The image below portrayes an adult female Evadne with almost fully developed embryos.
