    The word paludarium originates from the Latin word “palus” which stands for swamp. Paludariums are semi-aquatic terrarium habitats that replicate a rainforest, swamp or stream and can harbor aquatic as well as terrestrial animal and plant species. A paludarium combines the best of two worlds: an extra deep bottom allows you to incorporate a substantial water part or aquarium section adjacent to the land or terrarium section. A fully equipped and functioning paludarium is basically a small, closed ecosystem.

    The Exo Terra Landscaping Substrates mimic the natural soil found in arid regions, like deserts or savannahs. Most desert soils are not purely sand-based but rather a combination of sand, decomposed granite and clay resulting in interesting and sometimes colorful rock formations. Exo Terra’s Landscaping Substrates allow you to create your own desert or savannah landscape, including cool-humid burrows as well as warmer elevated basking areas.

    Reptiles are ectotherm, and use heat from an external source to thermoregulate their optimal body temperature. Most reptiles use direct radiant heat from the sun in combination with conductive heat from sun-heated surfaces such as branches, rocks or other heat accumulating structures. Providing such an appropriate, species related, temperature gradient in the terrarium is an important factor in successful reptile keeping. With the Exo Terra Thermostats you can create a well-controlled heating system that allows you to maintain the required temperature conditions similar to those found in a desert or tropical environment.

    The Exo Terra Misters are misting systems suitable for all types of terrariums and greenhouses. They help maintain optimal humidity by generating a fine mist which can be easily adjusted depending on the type of animal or plant housed. Frequent misting helps stimulate breeding behaviour, and is a necessity when housing live tropical plants such as Bromeliads, orchids, mosses, etc.


    The Exo Terra Sub Stratum is collected from the mineral-rich foothills of the Aso Volcano in Japan. The natural volcanic soil, formed from andesitic and rhyolitic tephra, is very nutrient rich, ideal for lush plant growth in bioactive planted terrariums. The porous surface allows for excellent drainage and aeration, supporting strong root growth. The Sub Stratum’s friable, low density structure promotes a flourishing population of beneficial, nitrifying bacteria, creating a self-sustaining, living terrarium ecosystem. The active beneficial bacteria of the soil will decompose biological waste, keeping the terrarium clean and healthy.

    The Exo Terra Reptile UVB NANO bulb emits optimal levels of UVA & UVB and is an excellent UV source for Nano Terrarium setups. The small dimension of this Reptile UVB NANO is perfect for use with the Exo Terra Reptile Deep Dome NANO; a fixture specifically designed for use on NANO and MINI terrariums. The bulb’s optimal Vitamin D3 yield index ensures vitamin D3 photosynthesis to aid calcium absorption and prevent metabolic diseases while the UVA rays will contribute to the animal’s overall wellbeing.

    The Exo Terra Incubation Devices make incubating reptile eggs safer, less complicated, and improve hatching rates. No matter if you prefer the Suspended Incubation Method or the more traditional Incubation Substrate method, with the Exo Terra Incubation Devices your reptile eggs are easy to incubate. The Exo Terra Incubation Devices are the only incubating devices on the market that control both temperature and humidity with high accuracy.

    The Exo Terra Dart Frog Terrarium is the ideal amphibian habitat designed by European herpetologists, perfect for bioactive planted setups. The single front opening door allows maximum viewing pleasure and provides easy access for maintenance and feeding. A push-button lock keeps the terrarium secure and can even be outfitted with an optional lock to prevent unwanted opening.


    Care Guides

    At Exo Terra, we understand that owning a reptile or amphibian is a unique and rewarding experience. However, it also comes with its own set of responsibilities. That’s why we’ve created this comprehensive resource to help you navigate the intricate world of herpetoculture and provide the best possible care for your animals.

    Whether you’re a beginner enthusiast or an experienced herpetologist, our academy offers a wealth of information, tips, and insights to enhance your understanding and skills in reptile and amphibian care. We cover everything from choosing the right habitat and selecting suitable species to creating optimal environments and maintaining proper nutrition.

    Academy

    Reptile keeping is a rewarding and fulfilling hobby requiring some basic knowledge and dedication. It is essential to understand the needs of the reptile species you are interested in keeping, as each species has unique requirements for temperature, lighting, diet, and enclosure size. In this section, you will find detailed information on the various species of reptiles commonly kept as pets, including their natural history, care requirements, and potential health issues.

    Expeditions

    In contrast to other animal groups, reptiles and amphibians are neglected subjects for expedition studies. Very few reptile communities have been adequately documented concerning their behaviour. A carefully conducted study lasting just a few weeks can significantly contribute to the pool of scientific knowledge for most species of lizards, snakes and amphibians.

A Hit with Both My Puppy and Older Dog!
I bought the Nylabone Moderate Chew FlexiChew Bone in the peanut butter and bacon flavor for my new puppy, and he absolutely loves them! What’s even better is that my other dog is just as obsessed with them, so it's been a hit with both. The size is perfect for my tiny puppy, and the flavor keeps them both engaged for a long time. These bones are durable enough to last, even with moderate chewing, and they help satisfy their natural chewing instincts. If you’re looking for a great chew toy for both puppies and small dogs, I highly recommend these Nylabones. They’re a definite favorite in our household!

Good quality

Very sturdy for super chewer dog. Only change I would make is I wish it held more kibble but dog loves it and I don’t worry she will choke on a broken piece when I’m away.

BEST DOG TOY for TREATS EVER!!!!
Color: Brown
If I could have given more than 5 stars, I would have! I had been giving my 70 lb boxer peanut butter in femur bones that I got at the pet store for years. She loved them but the bones would break down from chewing and biting on them. I would have to throw them away when the edges got sharp in fear of cutting my dog's mouth and tongue. This PETSWEET dog toy was the answer. I have been using yogurt, peanut butter and pumpkin so far. I freeze them with the goodies as is suggested. My dog LOVES her evening treat now and I don't worry about sharp edges hurting her mouth. It is washable so more sanitary than the femur bones.

Great for super chewer.
Color: Red
Update to original review: After leaving initial review the seller reached out and asked how to fix it the issue. I was willing to try same product again. They sent me two and I have had no problems with either of the new ones. Great communication from seller. My dog loves the treat In the center and chews on the product forever. She has not been able to get the top off of either of the new ones. Thanks!
