The information about mud turtles is great except for the part that says definitely that mud turtles do not require UV lighting because they live in black water where no UV penetrates...while it’s true UV rays would not pierce far into black water,mud turtle habitat is definitely not limited to or even necessarily more likely to be dark water...and the statement that they do no require UV exposure is no more a fact than it is to say that we have deciphered all there is to know about turtle care ...the idea that certain turtles don’t need UV lighting is a theory and nothing more it’s a little too widely accepted in my opinion to not have any more substantive data to back it...they bask regularly and in some cases do not even live in an area with an actual body of water but rather a marshy mud bog where they are often exposed to the sun but they also live in lakes and ponds and rivers and streams and creaks and swamps ....I have caught and released more wild specimens than I can remember and ALL of them while basking or foraging at the waters edge fully exposed to the sun...I am currently rehabbing a musk turtle that has as severe case of shell rot from to very poor husbandry ...and while it’s a best guess and part of a bigger picture of neglect ,my Herp vet has determined that the lack of a basking area and lack of UV lighting and poor water quality are the causative factors in this turtle horrible condition...treatment plan is a combination of daily cleansing of wounds followed by application of prescription strength topical antibiotics,followed by soaks in water treated with high amounts of tetracycline...and dry docking under uv lighting...the rate of recovery increased dramatically with the introduction of the UV exposure...this of course does not mean this experience can be called “proof” of anything...but it’s compelling and lined up with the natural behavior of these types of turtles...there isn’t a single species of aquatic turtle in North America that doesn’t bask...including alligator snapping turtles...why should they be doing this for any different reason than other species???uv lights are inexpensive and readily available...wouldn’t it be more responsible to tell readers that it is unclear if mud turtles require uv or not but to be safe,as we know it’s a need on some level or another,for all diurnal reptiles...to provide uv lighting as part of any aquatic turtle set up???
