![]() ![]() Tube feet are the second organ that takes part in the respiratory system of the starfish. This arrangement allows both the starfish’s arms to bend easily and the rapid onset of the stiffness and stiffness required for stressful breathing activities. They’re set at right angles to each other and arranged in a three-dimensional web with the ossicles and papulae in the crevices. These papulae are very soft tissue patches supported by collagen fibers. They contain extensions of the coelom (main body cavity) and enlarge the surface area for respiratory exchange. They are numerous thin-walled extensions on the starfish’s aboral surface (on top of their bodies). Skin gills are also called dermal gills or papulae. Instead of regular gills, starfish use two organs for breathing: skin gills and tube feet. Read on! Starfish skin gills and tube feet Furthermore, I’ll explain how starfish respiratory system works and if they can breathe out of the water. Below I’ll explain how starfish use their skin gills and tube feet for breathing. However, this doesn’t tell the whole story. They use their papulae (skin gills) and tube feet to absorb the oxygen directly from the seawater and exchange gases. However, let’s begin with a quick answer: If you wonder whether starfish have gills or not, we’ll talk all about that in this post. They adapted so well to their environment that they don’t need most of the organs we would expect them to have. Starfish are fascinating marine creatures without true brains, blood, or hearts. ![]()
