Although sea otters (Figure 5.16) are the smallest marine mammals, they are the largest mustelid (1.4 m in length). Disclaimer. Now that the sea urchins are hiding, Kelp forests (the urchins main food source) has the opportunity to grow vastly. This sequesters carbon for a time, but as pieces of kelp wash ashore and decompose, the carbon is released back into the atmosphere. River otters take oxygen from the air, just like other animals do. An otters, unlike a fish, does not use gill to harvest oxygen directly from the water; instead, they rely on their lungs and other respiratory systems for breathing. Scientists know that some kelp does end up in the deep ocean; how much, though, is difficult to estimate. Here, the sea otter occupy the dynamic costal areas with both the rocky and the soft sand habitat. of homrone x. 120 seconds. The acidification of the ocean also makes calcium carbonate-containing organisms less effective as food sources. The sea otter extends its feet out underwater to increase its surface area while it is seeking to shed heat. Secondly, oil spills result in the death of sea otters.

It uses its lungs, esophagus, trachea, and mouth to inhale and exhale oxygen. We studied geographical and temporal body size trends among 169 adult museum specimens of the Eurasian otter (Lutra lutra) collected in Sweden between 1962 and 2008, whose sex, year of collection, and locality were known. When urchins prey on otters, they act as grazers on kelp, increasing the amount of kelp that can be grown. Additionally, high water clarity can cause sea otters to overheat, as they rely on the water to regulate their body temperature. "I was pretty shocked," Estes says. In the 2015 study, Nicholson et al. 41 Votes) When low-oxygen events occur, Leary will be able to track their movements through the kelp forest. Fortunately, sea otters have an appetite for sea urchins and they help to keep sea urchins in check, allowing the kelp to flourish and capture CO 2. This site needs JavaScript to work properly.
