Species interactions
One niche that my organism has is that it is there are in the second level of the food web. They're in that category with larger fish, like lungfish, spiny sharks, and etc... The Common Octopus is a predator. The octopuses main predator is humans. The tissues and muscles of the octopus use oxygen and release carbon dioxide when breaking down glucose in the Krebs cycle. The carbon dioxide then dissolves into the blood or combines with water to form carbonic acid which decreases blood pH.
