La biodiversité marine
L'océan recouvre 70,8% de la surface de la terre
(soit environ environ 361 millions de kilomètres carrés)
profondeur moyenne:

Les océans abritent près de 250 000 espèces, mais nous n'avons exploré que 5% des profondeurs, il y a environ 80% des fonds marins non visités.
Il existe aussi des mammifères marins :
- dauphin
- marsouin
- orque
- phoque
- cachalot
- baleine
- et bien plus...
le requin n'est pas un mammifère marin, mais un poisson !
Bien sûr, il existe plusieurs espèces de chaque mammifère marin !
wow
Les tortues font donc partie de la famille des reptiles. Elles possèdent une carapace pouvant faire le double de leur poids!
* zone de mélange des eaux douces et marines
Différents milieux marins (écosystèmes)
* Île en forme d'anneau constituée de récifs coralliens
Estuaires*
Marais salés
Prairies sous-marines
Plages
Estrans rocheux
Et plus ! (rivières, lacs...)
Récifs coralliens
Atolls*
Mangroves
Mers
Océans
On a (je crois) tout dit sur la biodiversité marine... MAIS avez-vous bien compris ?
