UVB penetrates water????thats news to me ...can you cut the source of this information???Mud and musk turtles get a lot ad their D3 from diet. They do also use uvb but more in a floating style basking. UVB does penetrate water quite well. Hanging in plants near the sorface or in shallow water they will stretch their neck and front legs to absorb. Just as we've discussed with tortoises, a few hours a week of good exposure is enough uvb
