HOW DOES THE UV INDEX APPLY TO REPTILES?

The UV Index was developed as a tool for evaluating human risk of UV exposure outdoors. So how do we use it to evaluate UV lamps designed for use with reptiles in terrariums? This question was approached scientifically by a team of researchers led by the prominent herpetologist; Gary Ferguson, Ph.D. In their study, they took UV Index readings throughout the day in locations where they observed different species basking outdoors in sunlight or living in the shade. Using these UV Index readings, they were able to make recommendations for appropriate UV levels by creating four different UV Index “zones.” These zones were named the “Ferguson Zones” by Frances Baines (one of the authors and noted reptile photobiologist).

 

WHICH ZONE IS RIGHT FOR MY SPECIES?

Zone 1: UVI 0.4 to 0.7 (Shade/Crepuscular) Species in this zone can be either diurnal (active during the day) or crepuscular (active at dawn or dusk). They avoid direct sunlight exposure and are able to meet their vitamin D requirements through exposure to low levels of UVB typically found in the shade, or at dawn or dusk.

Zone 2: UVI 0.7 to 1.0 (Mostly partial sun/Occasional full sun baskers) This is a small range that is very close to Zone 1, but species in this zone will occasionally venture out into full sunlight for short periods of time. Examples include Green Anoles (Anolis carolinensis), Water Dragons (Physignathus cocincinus), Day Geckos (Phelsuma species), Skinks, Box Turtles (Terrapene species), Garter and Ribbon Snakes (Thamnophis species) and most species of diurnal Colubrid snakes (like Kings Snakes and Gopher Snakes). This zone is also recommended for Old World Chameleons (Panther Chameleons, Jackson’s Chameleons, and other Chameleo species). If you’re unsure what the appropriate zone is for a given species, Zone 2 can be used as a safe and effective level that will prevent the onset of metabolic bone disease or nutritional secondary hyperparathyroidism (NSHP).

Zone 3: UVI 1.0 to 2.6 (Mostly full sun/Occasional partial sun baskers) Zone 3 covers a fairly broad range and includes many species common to herpetoculture. These temperate, tropical, and sub-tropical species will bask in full sun early in the day or early afternoon. During mid day, they may be found basking when conditions are partly cloudy. This zone is appropriate for most species of aquatic turtles and tortoises. Many of the small spiny lizards of the genus Sceloporus fall into this zone, Monitors and Tegus, as well as Green Iguanas (Iguana iguana) and Curly-tailed Lizards of the genus Leiocephalus. With zone 3 and above, it is VERY IMPORTANT to provide a UVB gradient down to zone 1 UVB levels so that reptiles can “photoregulate” and adjust their UVB exposure as needed. Failure to provide a UVB gradient can result in illness, eye & skin damage, or even death.

Zone 4: UVI 2.6 to 3.5 or more (Mid day full sun baskers) Zone 4 species would include the majority of “desert” species that bask in full sunlight, even after Zone 3 species have retreated into burrows or the shade. Examples include Bearded Dragons (Pogona vitticeps), Uromastyx lizards, and Desert Iguanas (Dipsosaurus dorsalis). IMPORTANT: Just as with zone 3, it is critical that the habitat is large enough to provide a UVB gradient down to zone 1 levels to allow reptiles to photoregulate and adjust their UVB exposure. Failure to provide a UVB gradient can result in illness, eye & skin damage, or even death. Avoid UVI levels of 8.0 or more for zone 4 species as even the most sun-loving species retreat from full sunlight at these high levels (see lamp safety notes below for more info).

First ball was great!
Color: Black Green, Size: 8 Inch
This ball was great! My dog loves it. I ordered another smaller one. It had no pump and the inside was separated from the outside piece so it couldn’t be pumped up.

Fun and durable
Color: Flag, Size: 6 Inch, Color: Flag, Size: 6 Inch
I have a 5 month old teething Whippet puppy and this toy is a favorite. She loves carrying it around by the straps, playing tug, and trying to chew it. I think it’s pretty tough and durable for someone her size. I could see how a shepherd might destroy it quickly, though. I was surprised to find you have to inflate it, but the pump and needles are included and it hasn’t lost any air over several days of rough play. (I kick it and toss it to her. We tug with the straps. She carries it everywhere.) The material feels like a heavy duty soccer ball, just smaller. It’s the perfect size for her. I’d definitely buy it again.

It's a (smaller) soccer ball with nylon straps. Will no last long for aggressive chewers.
Color: Black Green, Size: 8 Inch
As the item title states, it's a soccer ball with straps. It feels like a soccer ball, but smaller and doesn't make any noises. The 8 inch size just right for my 50 lb dog. He can't get his mouth around the ball, but can bite down on the straps as we kick it around. He also plays and tosses it around by himself. It's also easy to clean. It's a good item, but suffers from two issues. 01) The nylon straps are tough, but not as durable as I though. My dog is aggressive chewer and has managed to chew them up a bit. 02) There is a nylon strap that is longer than all the others, so he tends to focus on that one. After about 15 days of playing with hit, he's managed to chew that strap up to the point that it's almost falling off. It would be nice if all the straps were the same, larger, size.

Highly recommend
Color: Black Green, Size: 8 Inch
I was skeptical that it would hold up to our aggressive chewer puppy (staffyX) - especially during teething. But it has survived past teething into adult chompers and is still fantastic! Its his favorite outside toy, especially the tags make it fun (and those have been holding up well too). If/when it fails, I'll buy another one.

great design, poor overall quality
Color: Black Green, Size: 8 Inch
My dog loves these balls. The "tags" are a great design. The problem I have is the quality as they aren't tough enough. He goes through them pretty quickly tearing off the tags and puncturing the ball. He doesn't get that these actually cost money! Each one also comes with a small pump, which I guess is great for a one time buy?, but man, if you don't own a pump just buy one and keep one. I have no use for several of these cheap pumps. How about offering the pump as an add-on for a dollar or two?
