An Mhórmhuir
Is í an mhórmhuir an ghnáthóg is mó ar domhan. Cuireann sí ocsaigin, báisteach agus bia ar fáil dúinn.
Meastar gurb é planctón 90% de na rudaí beo sa mhórmhuir. Créatúir mhicreascópacha iad don chuid is mó. Roinntear iad ina ndá ghrúpa, fíteaplanctón (plandaí agus baictéir) agus zóplanctón (ainmhithe).
Bíonn coiréil fuaruisce le fáil san Aigéan Atlantach amach ó chósta thar na hÉireann. D’fhás na cairn nó na sceireacha coiréal seo leis na mílte bliain.
