[yle="font-weight:bold;"> Marine Is an umbrella term for things relating to the ocean, as with Marine biology, Marine geology, and as a term for a navy, etc. In scientific contexts, the term almost always refers exclusively to saltwater environments, although in other contexts (e.g., engineering) it may refer to any (usually navigable) body of water.

turtle wiki:
[ext Turtles are reptiles of the order Chelonia, most of whose body is shielded by a special bony or cartilagenous shell developed from their ribs. The term turtle is usually used for the aquatic species, though aquatic fresh-water turtles are also called terrapins. The term is sometimes used (esp. in North America) to refer to all members of the order, including tortoises, which are predominantly land-based. The order of Testudines includes both extant (living) and extinct species. About 300 species are alive today. Turtles are now highly endangered, largely due to beach development and over-hunting.
