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).

Pretty good size, and storage but it moves a little.
Color: Black, Size: 7.9" x 3.7" x 6.2"
I ordered this in black, and it holds a large bottle of hand soap, my dish wand, and two other sponges/scrubbers. It really does drain into the sink, but you have to be careful to place it on the edge of the sink, or the water will drip onto the counter. Also, it's very light, so if you only have a few items in it, it's likely to move or fall when you reach for a sponge. Since we put a solid bottle of hand soap in there, it is much more stable, even when I'm using the pump dispenser. I can't tell if it's rustproof for long-term use, but so far it's functional after adding something to weigh it down. I like it much better than the flat sponge caddy we had before, and the quality seems good. I would like it to be more stable, but otherwise it's useful

Compact, Versatile, and No Rust So Far
Color: Black, Size: 7.9" x 3.7" x 6.2", Color: Black, Size: 7.9" x 3.7" x 6.2"
I looked around quite a bit before buying this because a lot of sellers offer the same or very similar design. I even saw versions with a dedicated spot for a Scrub Daddy, but I didn’t feel like paying extra for that. I went with this one hoping it would still work for my setup, and it absolutely does. I’m limited on counter space, and this doesn’t take up much room at all. The removable brush holder cup is a big plus, I removed it and use that space for my Sponge Daddy, which fits perfectly. It also fits my hand soap and dish soap bottles without any issues, and I use the brush holder section to hold clean utensils. I’ve been using this for almost two months now and wash dishes constantly, so there’s pretty much always some water dripping from the sponge while it dries. So far, there’s been no rusting and no color chipping, which was something I was concerned about. Overall, it works perfectly for my needs and feels well made.
