[…]season. Amplexus and egg-deposition occurs on land. Thereafter, males guard their 20-40 large eggs for approximately 20 days. Once the tadpoles begin moving within the eggs, they are taken into the male’s mouth and maneuvered through openings that lead into the vocal sac. Perhaps as an adaptation to its most unusual […]
[…]in 1-7 hours, and can include 50 -350 individual egg-laying trips to the surface; as many as 1,000 eggs may be deposited. The Eggs The tiny (2 mm diameter) eggs float and stick to aquatic plants. Those of H. curtipes are brownish in color; H. boettgeri eggs are a bit […]
[…]to manipulate the hatchlings’ sexes. Please post below for further information. When removing eggs from a terrarium, be sure to make a small pencil mark at the top of each, so that they are not accidentally rotated. Oils from the skin can clog air pores, so use powder free gloves […]
[…]below if you need a reference to a local veterinarian experienced in turtle care. Hatching the Eggs While the eggs of Common Snapping Turtles and other consummate survivors will often do well at room temperatures (in a hot room, in summer), a reptile egg incubator will greatly simplify the hatching […]
[…]arrives. Please see these articles for further information on collecting insects. Incubating the Eggs Eggs may be incubated in vermiculite or moist sphagnum moss. I prefer to use a vermiculite and water in a 1:1 ratio by weight (please see this article for details on setting this up), but success […]
[…]suffocation as the cause of death. Reproduction Females guard and incubate clutches of 20-100 eggs, which hatch in approximately 90 days. Hatchlings typically measure 16-24 inches in length. Taxonomy Many herpetologists classify the African Rock Python as Python sebae. Others recognize two subspecies – P. s. sebae, the Northern African […]
[…]pet food. They are also extremely interesting in their own right, with females caring for their eggs and actually carrying food to the young! Why Earwigs? Earwigs are readily accepted by a wide variety of reptiles, amphibians, tarantulas, fishes, and scorpions, and provide nutrients absent from commercially-reared insects. They are […]
[…]and Odd Snake Meals From Caiman, Siamese Cats and African Hunting Dogs to centipedes and frog eggs, snakes have been observed feeding on many “unexpected” food items. In Venezuela, a Green Anaconda grabbed my co-worker, in what appeared to be a feeding attempt, while a recent study documented 150 Reticulated […]
[…]over plants is a useful option. Breeding Well-nourished females may produce 2-3 clutches of 10-50 eggs yearly. Incubation periods of 6-8 months have been recorded, and the young reach sexual maturity 6-8 month of age. Captive reproduction can be tricky; please post below for further information. Handling Chameleons are best […]
[…]the family Dendrobatidae or Aromobatidae. Those species that have been studied deposit their eggs on land. Males transport the tadpoles to water at varying points in their development. Most of the new frog’s relatives seem to have very small natural ranges. Any disturbance, even carefully-planned ecotourism, may put them at […]
[…]eggs sent danger signals, apparently via vibration, to the youngsters within. (Red-Eyed Treefrog eggs are attached to leaves overhanging a pond. When under attack, tadpoles burst from their eggs, fall into the water, and swim off). It is not known whether other of the Delicate Skink’s 10 relatives, collectively known […]
[…]artificial bromeliads, which are equipped with tiny “ponds” in which frogs can deposit their eggs or tadpoles, are very useful (please see photo). An easily-cleaned, bare-bottomed tank, tilted on one side to create a water section, is ideal for African Bullfrogs, Horned Frogs and other giants that require frequent water […]
[…]are lung-less and tongue-less frogs, gliders and burrowers, frogs that brood their eggs in vocal sacs and others that form lifelong pair bonds. The first time I bred Surinam Toads, and witnessed 100 tiny frogs emerging from their mother’s back (please see photo), I thought I had seen the oddest […]

[…]that may live for 10, 20 or even 50 years. Among them we find creatures that glide, brood their eggs in vocal sacs, form lifelong pair bonds and exhibit other fascinating behaviors. While the smallest is barely as large as a pea, the nine-pound African Bullfrog can chase lions away […]
[…]Frogs”. Treefrogs that Break the “Frog Breeding Rules” Some treefrogs deposit their eggs on leaves over water, while others breed in tree hollows in the forest canopy. It was recently discovered that the tadpoles of India’s Brown Leaping Frog live on tree limbs and eat bark, while those of […]
[…]it follows that diurnal amphibians will receive some exposure. On the other hand, the skin and eggs of some amphibians contain chemicals that filter-out UVB. We still have a great deal to learn. Providing UVB to Pet Reptiles and Amphibians Natural sunlight is the best source of UVB, but please […]
[…]wrestle for dominance during the mating season (please see photo). Females deposit 6-17 eggs in mammal burrows, termite mounds, tree hollows and similar sites. The hatchlings average 15-24 inches in length. Black Mambas grow very quickly, with well-fed individuals reportedly reaching a length of 6 feet within their first year […]
[…]coccinea, is rarely kept by hobbyists or zoos because of its preferred diet of lizard and snake eggs. A specimen in South Carolina, however, consumed a young, dead Corn Snake with which it had been temporarily confined. The Southern Hognosed Snake, Heterodon simus, is widely “known” to be a confirmed […]
[…] Females scrape together a mound of dead vegetation in which to deposit their 20-30 large eggs, but appear not to guard the nest or young. Eggs are likely lost to wild pigs, Water Monitors and other predators. Conservation The False Gharial is extinct in several countries and is threatened […]
[…]biology, so captive breeding is not considered an option. There is some evidence the eggs of lizards such as the St. Lucia Whiptail (Cnemidophorus vanzoi, please see photo) make up much of its diet, but it likely takes lizards, frogs, small mammals and birds as well. St. Lucia’s Other Reptiles […]
[…]as their pugnacious parents. Poison Frog tadpoles of several species feed upon unfertilized eggs deposited by their mother, Goliath Frog, Conraua goliath, tadpoles consume a single species of algae, Fringe-Limbed Treefrog (Ecnomiohyla rabborum) tadpoles eat their father’s skin, Brown Leaping Frog (Indirana semipalmata) tadpoles gnaw on wood (high up in […]
[…]species for much of their lives. Reproduction Limited observations indicate that several hundred eggs are attached to aquatic vegetation in quiet pools among the rapids. The tadpole stage lasts for 2.5 to 3 months. In common with certain other frogs that inhabit noisy, rushing streams, Goliath Frogs produce no mating […]
[…]pink mice can be offered 1-2 times weekly. Canned snails and grasshoppers, and hard-boiled eggs, can be used to provide variety. Nile Monitors and similar species fare well on mice and rats alone; whole freshwater fishes are an excellent rodent-alternative for Water and Merten’s Monitors. Food (other than vertebrates) should […]
[…]low intakes. As a corner filters outflow is directed upwards, strong currents that might disturb eggs, larvae or weak-swimmers are avoided. Corner filters can be easily hidden with plants. Live Java Moss is ideal for this purpose. Sponge Filters Sponge filters provide mechanical and biological filtration, and are ideal for […]
[…]time to look and learn. Frogs that dye human skin yellow, snakes that specialize in eating only eggs or snails, iridescent skinks sporting tails twice their body length…the list is simply astounding. Today I’ll highlight a few that have especially captivated me; please post your own favorites (whether covered here […]
[…]a variety of health concerns, including dehydration, depressed immune systems, parasites, retained eggs, malnutrition and shipment-related injuries. Please see this article, and be sure to purchase only captive-bred animals. Please check out my posts on Twitter and Facebook. Each day, I highlight breaking research, conservation news and interesting stories concerning just […]
[…]orange to grayish-brown as it matures. There are some indications that females remain with their eggs for a time. Unique scalation lends the alternative common name of Keel-scaled Boa. Juveniles and some adults (especially females) appear to be largely arboreal. The Round Island Boa’s preferred habitat – forest and palm-dotted […]
[…]skin folds (for oxygen absorption) suit the Ghost Frog for life near fast-moving streams. Its eggs have never been found. Hellbender, Cryptobranchus alleganiensis As a child, I was fascinated by this heaviest of North America’s salamanders, and couldn’t imagine why grown men considered it “from hell” and would reportedly cut a […]
[…]and initiate digestion; food is consumed in liquid form, in the manner of spiders. Reproduction Eggs are inserted into living or dead plants, and hatch in 2-4 weeks. The nymphs resemble the adults (incomplete metamorphosis) and mature in 4-6 weeks. Captive Care Enclosure The aquarium should be covered and the […]
[…]balls during the breeding season and a taste for a wide variety of creatures…birds and their eggs, fish, lizards, caiman, capybaras, pacas, brocket deer and a host of other animals have been recorded as prey. Green Anaconda, Eunectes murinus I’ve captured and tagged some very large Green Anacondas, and have […]
[…]the fall and winter may also be useful, but is not critical (please write in for details). The Eggs Gravid female swell noticeably, and their 2 eggs will be visible through the skin in time. A well-fed female may produce 3, or possibly more, clutches of 2 eggs each. I’ve […]
[…]in Captive Diets Amphipods are readily accepted by newts of all types, Mexican Axolotls, many turtles, and aquatic frogs such as African and Dwarf Clawed Frogs and Surinam Toads. Salamander larvae and carnivorous tadpoles relish smaller species. They can also be offered to terrestrial salamanders and frogs; in these cases, […]
[…]outdoor carpets are preferable. Females without access to suitable nesting sites may retain their eggs; please see this article for information on captive breeding. Light Green Iguanas will not thrive without a source of Ultra-Violet B light. Natural sunlight is best, but be aware that glass and plastic filter out […]
[…]– killing a few dozen workers will not reduce ant numbers but instead may set up a call for more eggs! Boric Acid Toxins that are taken to the nest and shared among the colony can be effective against Pharaoh Ants (Monomorium pharaonis, the most common indoor ant in many […]
[…]not taken as prey). Fierce predators in their own right, Fire Ants also attack lizards and their eggs. They likely affect plant communities as well, which in turn can impact horned lizard survival by altering the environment. Introduced Indian Mongooses are driving the St. Croix Ground Lizard to the brink […]
[…]via tongs to limit potential problems. Health Considerations Females may be troubled by retained eggs and other reproductive disorders if they do not mate. In order to avoid these life-threatening conditions, unmated females should be spayed. Gravid females need an appropriate nesting site…please write in for further information. Water Dragons are […]
[…]and deposit their small clutches of eggs on land. One or both parents may guard and moisten the eggs. Some species transport the tadpoles to pools of water upon their backs. Female Strawberry Poison Frogs and certain others lay unfertilized eggs as food for their tadpoles, awaiting a signal from […]
[…]female Senegal Chameleons. Depressed calcium levels will prevent the female from expelling her eggs; veterinary intervention is essential if death is to be prevented. The lack of a suitable nesting site can also cause a female to retain her eggs, even if she is in good health. Please write in […]
[…]years after its “near-death experience”. Other interesting experiences have involved Mexican Axolotls. An individual in my collection became bloated and was unable to submerge. A veterinarian who worked with me at the Bronx Zoo prescribed Itraconizole and other medications, but the infection proved resistant to all. I refrigerated the animal […]
[…]Music Frog is native to marshy habitats in central and southwestern China. Females deposit their eggs in burrows constructed by the males, and the tadpoles develop there as well. The ability to construct a safe burrow is, therefore, an important consideration when females go “mate shopping”. You can see photos […]
[…]Crickets breed readily, with the best results being had at 82-90 F. Females will deposit their eggs in bowls stocked with 2 inches of moist sand or earth. These should be removed often, as adults love snacking on their own eggs. Hatching occurs in 1-2 weeks at 85-90 F, and […]
[…]became one of the few of her kind to reproduce in captivity, and yearly rewarded us with fertile eggs. The heads of the male River Terrapins darken during the breeding season, and white eye-rings develop. We were able to document a display during which males pumped their throats and possibly […]
[…]fed very well, and are good at negotiating domestic squabbles!). Female Leopard Geckos produce 2 eggs, which are often visible beneath the skin as they develop. Remove the male once copulation has been observed, or you notice a weight gain; watch also for overly aggressive males. Copulation is accompanied by […]
[…]numbers, and remains an excellent introduction to snake breeding. Females produce clutches of 8-26 eggs, sometimes twice yearly, and the 8 – 11 inch long hatchlings are not difficult to rear. Please see the article below for further information. Further Reading Corn Snake History, Breeding and Color Phases […]
[…]they are likely on the menu of predators ranging from spiders to small birds. Females produce 2 eggs, but the details of their reproductive biology are unknown. I’m looking forward to reading more about their lifestyles, especially their diet. Some years ago, I cared for a colony of tiny Kihansi […]
Dietary variety is the key to success in rearing many herps and invertebrates. Unfortunately, options for newly-transformed frogs and salamanders, Poison Frogs and other small species and hatchling spiders are limited. A diet of fruit flies, springtails and pinhead crickets sometimes suffices, but as I learned when rearing the endangered […]
[…]and legs. The female is eventually led to a nest site below the leaf litter, where she lays 4-6 eggs, which are externally fertilized. The male moves from clutch to clutch, shedding water on the eggs, rotating them and removing fungus. Males seem able to predict hatching, and are nearly […]
[…]food in water-filled jars (stuffed with cotton) so that it remains fresh. Unfortunately, the eggs of most US natives require a period of cold temperatures if they are to hatch. I’ve had some luck refrigerating eggs at 38 F for 4 weeks, but the technique needs fine-tuning. Collecting (in pesticide-free […]
[…]herpetologists Mary and George Rabb. An Unusual Degree of Parental Care Females deposit 60-200 eggs in pools of water located in tree hollows above ground. The tadpoles are large, and in time their body mass may exceed the volume of water held in the cavity. Perhaps this is why such […]
