Sea otters: Surprising global warming warriors have effect on CO2 Total oxygen storage capacity matures rapidly in sea otters, reaching adult levels by 2 mo postpartum. Despite their short lives by plant standards, kelps siphon huge amounts of carbon from the atmospherewhat scientists call primary productivity. They take carbon dioxide from the air and turn it into sugar fuel with the help of sunlight and water, releasing oxygen back into the air. Sea otters decrease heat loss by floating on their backs with their feet out of the water when the water is too chilly. Although kelps are highly productive, theyre much less massive than the terrestrial trees, and therefore, they cant hold onto as much of that carbon they suck from the atmosphere. the lack of natural predators. When urchins prey on otters, they act as grazers on kelp, increasing the amount of kelp that can be grown. Also, too much sediment or other particles floating in the water absorb heat from sunlight. The fourth otter was a 9-10-yr-old female with a mean mass of 6.7 kg. This leads to an increase in turf algae growth, which then displaces the kelp.
