Product Description

Daphnia - water fleas.


Phylum: Arthropoda.
Class: Crustacea.
Sub-order: Cladocera.

Qty: 40.

Daphnia are commonly known as Water Fleas due to their size, shape and movement. They are found in ponds and waterways. Their transparent shell covers their legs and pointed spine, and in some cases, the shell also covers the head. Distinctive feathery antennae stand stiffly outstretched. These allow Daphnia to move in a zigzag motion as they feed on suspended bacteria and green protists.

Daphnia reproduction is parthenogenic (eggs develop without being fertilized). Eggs undergo development in a brood chamber and hatch there as fully developed young.

Open water Cladocerans undergo a vertical migration during each 24 hour period. These drifting populations commonly move upward with the onset of darkness and downward with the coming of dawn.
