Cocailiteafóir (fíteaplanctón)
Tá cocailití níos coitianta sna farraigí teo ná i bhfarraigí measartha an tuaiscirt. Fágann siad dath bán an bhainne ar an uisce nuair a bhíonn siad flúirseach. Thit cocailití marbha go grinneall an aigéin na milliúin bliain ó shin. Rinneadh aolchlocha ar nós cailce díobh trí phróisis gheolaíocha le himeacht aimsire.
Coccolithophores (phytoplankton)
Coccoliths are more common in warmer seas than in northern temperate seas. Large numbers give water a milky-white appearance. Millions of years ago, dead coccoliths sank to the bottom of the ocean. Through time and geological processes, these formed limestones such as chalk.
