This led to the extinction of the Steller's Sea Cow and the Caribbean monk seal. [3] Today, populations of species that were historically hunted, such as blue whales Balaenoptera musculus and B. m. brevicauda), and the North Pacific right whale (Eubalaena japonica), are much lower compared to their pre-exploited levels.

The marine life found in the Canary Islands is interesting, being a combination of North Atlantic, Mediterranean, and endemic species. In recent years, the increasing popularity of both scuba diving and underwater photography have provided biologists with much new information on the marine life of the islands.
Surface-living animals (such as sea otters) need the opposite, and free-swimming animals living in open waters (such as dolphins) need to be neutrally buoyant in order to be able to swim up and down the water column. Typically, thick and dense bone is found in bottom feeders and low bone density is associated with mammals living in deep water.
Higher trophic levels include all predators of octopuses, and may fluctuate with octopus abundance, although many may prey upon a variety of organisms. Protection of other threatened species may affect octopus populations (the sea otter, for example), as they may rely on octopuses for food.
Animals are multicellular eukaryotes, [note 1] and are distinguished from plants, algae, and fungi by lacking cell walls. [1] 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.
