SMALL FRY

Animal Scene - - FINS, FEATHERS, AND FUR -

Newly hatched brine shrimp mea­sures less than 1 mil­lime­ter. An Artemia’s ma­ture size can reach 15 mil­lime­ters in length. They nor­mally swim in up­side­down, reg­u­larly thump­ing their legs.

Dur­ing the first few days af­ter hatch­ing, Artemia feed them­selves by con­sum­ing their own en­ergy re­serves stored in the cyst. Wild ones con­sume mi­cro­scopic al­gae. Cul­tured ones can be fed yeast, wheat flour, soy­bean pow­der, and egg yolk.

In­ter­est­ingly, their cysts can re­main vi­able for up to 25 years.
