So the team looked at a range, from a conservative one percent up to 50 percent of shed kelp ending up in the depths. How to balance the interests of fishermen with the need to support the recovery of sea otters has been debated back and forth, often failing to take into account the full scope of the problem, Estes says. Although sea otters (Figure 5.16) are the smallest marine mammals, they are the largest mustelid (1.4 m in length). The marine mammals consume on average one-fourth of its weight daily including sea urchins, which are vital to support the kelp forests. Sea otters were nearly hunted to extinction during the fur trade in the 18th and 19th centuries. All over the world there is a subject that has an effect on us all, and that subject has come to be known as climate change, or more commonly global warming. Several creatures that shelter in the kelp have to venture in the opening to feed, like the bat ray. Starting from the sun, create a food chain including at least three organisms. Without sea otters, sea urchins and other herbivorous invertebrates are left unchecked to graze through swathes of giant kelp forests, creating barren stretches of coastal habitat behind them that once served as nurseries for fish, seals and hordes of other sea life. As a result, when oxygen levels are reduced, the net primary production (NPP) of organic matter that supports the food web and ecosystems may be hampered.
