Hot Weather Herp Tips – Summer’s Effect on Reptiles and Amphibians

Estimated read time 5 min read

Most herp fans know that amphibians are normally fairly delicate to heat temperatures. Nonetheless, reptiles, even these native to tropical and desert habitats, could also be severely impacted as nicely. Following are some basic tips to remember on the top of summertime – please write in for extra detailed details about the animals in your assortment.

Normal Concerns

Even inside the hottest of pure habitats, herps discover methods to flee temperature extremes. Thousands and thousands of years of evolution have introduced us to many excellent surprises in this regard – Australia’s Water Holding Frog, for instance, thrives the place most unprotected creatures, even reptiles, would prepare dinner briefly order. So whereas desert-tailored animals could also be higher suited to resist warmth, don’t assume that they will be nice without consideration.

Many herps stay lively in extreme habitats using distinctive “micro-habitats” – areas that remain cool or damp regardless of basic situations. Thus, Massive headed Turtles inhabit cool streams in heat areas, leaf litter, and bigger animals’ caves enable Gopher Frogs, Caecilians, and different “delicate” amphibians to inhabit areas that ought to, in idea, be too sizzling to help them and so on.

Water chillers, air conditioners, and trout-holding tanks can all be put to good use throughout the sizzling climate. Basements, when accessible, are a beautiful, useful resource. Most basements I’ve used within the NYC space ranged from 66-70F in the summertime and 52-56F in winter.


Except for a few species (i.e., the African Gray Treefrog), most amphibians weaken and die in temporary order when pressured to endure sizzling and/or dry situations. Cool temperatures are normally preferable…actually, analysis labs generally refrigerate Leopard Frogs to curb “red leg” infections, and I’ve had good outcomes doing the identical for Mexican Axolotls. On two events throughout my time on the Bronx Zoo, “dead” salamanders positioned within the hospital’s necropsy fridge had been discovered to be alive and kicking the subsequent morning!

The temperatures favored by amphibians will be fairly shocking. I, as soon as refrigerated a bunch of Hearth Salamanders to induce hibernation, however, discovered them foraging for meals even at 40 F.

Though labor-intensive, coolers provisioned with reusable gel ice packs make good summertime houses for significantly delicate amphibians. A fairly “intense” good friend of mine stored Black-Chinned Pink Salamanders in this manner, altering the packs twice every day for over 20 years. I inherited one in every one of his salamanders, which is now a minimum of 31 years previous, so the method does work!

Those who hold tadpoles, salamander larvae, or wholly aquatic species keep in mind that heat water contains much less oxygen than cool water. Gilled larvae are, due to this fact, vulnerable to suffocation. Neotenic salamanders akin to Mudpuppies and Axolotls have lungs however want to depend on their gills and pores and skin for oxygen switch. As temperatures rise, they’ll start to wave the gills to create water currents or will swim to the floor for air. It will stress them and weaken the immune system.

Some amphibian keepers reap the benefits of the summertime’s warmth by permitting their animals to aestivate or grow to be dormant. It is a difficult prospect (please write in for particulars); however will be the very best course, and even a breeding stimulus, for some species. Sirens, African Bullfrogs, Water-Holding Frogs, and Spadefoot Toads are among the many champion “summer sleepers.”

Turtles and Tortoises

Regardless of a propensity for basking, tropical climes, and deserts, Chelonians are usually not proof against temperature stress. Some species, akin to Massive Headed and Lavatory Turtles, are recognized to favor quite cool temperatures. Whereas they might not expire within the method of amphibians, such turtles might endure well-being issues introduced by an over-worked immune system and the stress of looking for a good retreat. Lavatory Turtles beneath my care at the Bronx Zoo, housed in a heat holding space, fared significantly better as soon as chillers had been put in of their enclosures.

Widespread Snapping Turtles are lively at very low temperatures and have even been seen shifting about in ice-covered ponds. Captive grows to be stressed when water temperatures exceed 85F or so, one thing I’ve seen in Widespread Musk Turtles as nicely.

Maybe due to their “tortoise-like” look, American Field Turtles are sometimes stored at inappropriately high temperatures. They fare finest at 72-75F, with entry to a hotter basking spot. Dry situations have been linked to eye and ear illnesses, so make sure to use moisture-retaining substrates and mist recurrently. A water bowl or pond massive sufficient for soaking should at all times be accessible.

Even desert-adapted tortoises (particularly hatchlings) may have particular consideration in the summertime. For instance, Egyptian Tortoises keep away from temperature extremes by remaining dormant, and within the wild could also be lively for only some months every year. These I stored turned very dormant when subjected to heat temperatures 12 months spherical.

Snakes and Lizards

Tentacled Snakes inhabit shallow, nonetheless waters in Vietnam, Cambodia, and Thailand, which could be anticipated to be well-adapted to heat temperatures. But all that I’ve stored would go away the water (an unnatural and, given their clumsiness on land, harmful conduct) when temperatures exceeded 84F.

Clean and Keeled Inexperienced, Brown (DeKay’s), Pink-Bellied and Ring-Necked Snakes, and different small, insectivorous species, are fairly vulnerable to dehydration and warmth stress. Though they want an opportunity to dry out, a cool, moist retreat is important to their well-being.

Many lizards favor sizzling, dry situations. However, even desert-adapted species have their limits. For instance, discipline analysis has proven that Gila Monsters (Not an animal I’d suggest as a pet!) spend nearly all their time in cool, damp caves. Sure lizards, such because the Crocodile Skink, favor surprisingly low temperatures, whereas others, such because the Inexperienced Anole, are vulnerable to dehydration in an arid environment. As at all times, analyze your species’ pure historical past earlier than making any assumptions, and please be happy to put it in writing if you need help.
