Most oxygen enters the starfish via diffusion into the tube feet (with the water vascular system), or the papulae (small sacs covering the upper body surface). Reproduce alone, or with a mate: Sea stars are capable of both sexual and asexual reproduction. Individual sea stars are male or female.
Specifically for keratosis pilaris, I would make extra certain that you are not eating foods with new-fangled vegetable oils such as corn, sunflower, vegetable a.k.a. soybean, grape seed, cottonseed AND canola oils. These non-traditional vegetable oils are packed with super unstable PUFAs (poly-unsaturated fatty acids).
Keratosis pilaris results from the buildup of keratin â a hard protein that protects skin from harmful substances and infection. The keratin forms a scaly plug that blocks the opening of the hair follicle. Usually many plugs form, causing patches of rough, bumpy skin. No one knows exactly why keratin builds up. But it may occur in association with genetic diseases or with other skin conditions, such as atopic dermatitis.
