What are marine invertebrates?

Marine invertebrates are animals that inhabit a marine environment apart from the vertebrate members of the chordate phylum; invertebrates lack a vertebral column. Some have evolved a shell or a hard exoskeleton .

Ecosystems may vary in size, but all the parts of the ecosystem depend upon each other; if one part of the ecosystem is removed, it affects everything else. A marine ecosystem is any that occurs in or near salt water, which means that marine ecosystems can be found all over the world,…

Why do marine mammals live in water?

What are marine mammals?

Marine mammals are warm-blooded vertebrates (animals with a backbone) that bear live young and nourish them with milk as land mammals do, but that spend most or all of their lives in the ocean. They are broken into three groups that share similar adaptations to their aquatic life, but that have very different origins and life patterns.

What is the role of marine mammals in ecosystems?

While the number of marine mammals is small compared to those found on land, their roles in various ecosystems are large, especially concerning the maintenance of marine ecosystems, through processes including the regulation of prey populations.

What is the distribution of marine mammals?

Marine mammals are widely distributed throughout the globe, but their distribution is patchy and coincides with the productivity of the oceans. Species richness peaks at around 40° latitude, both north and south.
