[…]the Rosy Boa can be. They are live bearers, so breeders are spared the trouble of incubating eggs, and the 3-6 young typically produced are large enough to accept pink mice. Garter Snakes, Thamnophis spp. Over 30 species of these attractive, interesting snakes may be found in North America. Garter […]
[…]raise their own core temperatures and that of the egg clutch. Female Burmese Pythons lay 18-100 eggs after a gestation period of 60-150 days. The eggs hatch in 55-75 days. The hatchlings are 18-24 inches long (large enough to consume adult mice) and become sexually mature at a length of […]
[…]is continually added to the retained eggs, draining the female’s supplies and rendering the eggs ever-more difficult to pass. Eventually, the eggs will break and/or decay, and an infection known as egg yolk peritonitis will set in. If untreated, the female will die. Determining if your Turtle is Gravid Another […]
[…]and commonly sold as food for tropical fishes. I experimentally raised the larvae of Mexican Axolotls and Spotted and Marbled Salamanders solely upon blackworms, and had excellent results. Avoid Tubifex Worms, which are harvested from polluted waters. Live Earthworms are a near-perfect food for most newts (and amphibians in general), […]
[…]ponds, vernal pools, and marshes as winter ends (December in the south, May in the north). The eggs are attached to submerged vegetation at or near the water’s surface, often in areas that receive a good deal of sunlight. The eggs hatch in 8-24 days. The tadpoles feed upon algae […]
[…]Frog and certain other tadpoles develop within a moisture-retaining nest. The Brown Leaping Frog eggs were at least 10 feet from water, and not in a position to be carried there by rain. Also, this was the first time any frog has been observed attaching eggs to tree bark. A […]
[…]can raise their core temperatures and the temperature of the egg clutch. Females deposit 30-100 eggs after a gestation period of 100-150 days. The eggs hatch in approximately 85 days. The hatchlings are 30-32 inches long-large enough to consume adult mice right away and become sexually mature at a length […]
[…]but cork bark offers, I believe, the best attachment site). The jelly surrounding each clump of eggs is extremely thin, so take care not to jostle the caves when you check them. The eggs hatch in 10-12 days, at which time the tadpoles slide down strands of jelly (which may […]
[…]on the pond bottom in densely vegetated sites. There is some evidence that females may guard eggs, but we do not as yet know whether fertilization is internal or external (great project for an aspiring keeper!) The eggs hatch in April and May; very little is known of larval period. […]
[…]in rodent burrows, and have even been seen to enter iguana and sea turtle nests to prey upon eggs. Captive Care Mexican Dwarf Pythons can be kept as has been described for Calabar Ground Pythons, but need a drier substrate and less misting. A shredded bark – sand mix suits […]
[…]efforts and very willing to consume their progeny. Amazingly, a female in my collection deposited eggs without entering amplexus, and a male fertilized the eggs the following day…please see the article below for details. Observing Breeding Behavior Despite their generally bold demeanor, paired African Clawed Frogs are extremely sensitive to […]
[…]miles) area in Dade County. Among the captured snakes was an 15.5 foot-long adult female with eggs forming in the oviduct, reproductively active males, and several young-of-the-year. The ages and sexes of these snakes, and their proximity to one another, suggests a breeding population. Also notable is the fact that […]
[…]and a filter that does not create strong currents (corner filters are ideal). Females lay 100-200 eggs, usually within 24 hours of entering amplexus; the eggs attach to plants, sticks and airline tubing. At 72 F, the tiny (7 mm) tadpoles hatch in 3-4 days. They remain motionless and attached […]

Hispaniolan Crowned Frog: sporting a head ringed by bumps, this arboreal frog breeds in Bromeliads. Further Reading Conservation Update: the Lake Titicaca Frog Haiti’s Lost Frogs; includes […]
[…]be more widespread than is generally believed. Reproduction Mating occurs in the spring and 2-9 eggs are laid in the summer. The young, 12-15 inches in length, hatch after an incubation period of 2-3 ½ months. Hatchlings feed mainly upon small lizards. Diet Lizards are said to be favored, especially […]
[…]to a live-bearing lizard! Populations in New South Wales’ warm coastal regions produce eggs, while those inhabiting cool mountain slopes give birth to live young. Cool temperatures are associated with live-bearing in herps ranging from Alpine Newts to European Vipers, but only 2 other lizards (Bougainville’s Skink and the Viviparous […]
[…]reports indicate that Giant Horned Lizards mate in April-June, with gravid females laying 10-30 eggs after a gestation period of 60-70 days. The eggs hatch in 10-12 weeks when incubated at 85 F. Horned Lizard Care Horned Lizards are hard to resist, but it is a mistake to attempt keeping […]
[…]eat nearly every day without fear of obesity setting in. Breeding Clutches range in size from 6-15 eggs; when incubated at 85F they hatch in approximately 275 days. Mertens’ Monitors have evolved in habitats subjected to fluctuating weather extremes, and their eggs are quite resilient – incubation periods of 180-330 […]
[…]gills, never see the light of day, do not mature until age 16, and reproduce by both laying eggs and bearing live young. Despite their very unique natural environments, Olms do quite well in zoos, often living into their 70’s. Due to the Olm’s rarity, researchers have maintained a breeding […]
[…]not to puncture veins, as their common name suggests! The unique tadpoles seem to hatch from eggs deposited in water-filled tree hollows high above the ground, but beyond that we know nothing of their natural history. Tadpole Teeth Tooth structure is an important means of identifying tadpoles, especially given that […]
[…]the breeding season. Females dig a burrow, which terminates in a leaf-lined chamber, for their eggs. There is evidence that, at least in certain populations, gravid females migrate to small, temporary water bodies before nesting; perhaps this safeguards the young from Salt Water Crocodiles, Crocodylus porosus, and other river-dwelling predators […]

[…]and other plants, where they mature. Females of several species return to deposit unfertilized eggs as food…some even wait for a signal from the tadpole before laying (please see article below). Artificial Tadpole-Rearing Pools Keeping these little gems in a terrarium furnished with live plants is ideal, but not everyone […]
[…]All Assassin Bugs, including the US natives, should be handled only with forceps. Assassin Bug eggs and nymphs are very tiny, and usually go un-noticed – be sure to use fine grade insect screening over their terrariums to prevent escapes. Environment and Breeding Red and White-Spotted Assassins can be […]
[…]seem not to remain nearby). Amazingly, in 8 instances a male joined the female in protecting the eggs. Other Rosenberg’s Monitors are the primary threat to eggs. Females guarding nests attacked male intruders twice their own weight, and repelled them in most cases. The vicious fights that ensued frequently left […]
[…]upon the latitude, with mating concentrated in the spring. The average clutch contains 2-5 eggs (range 1-9); 4 clutches per year may be produced in the southern part of the range. The eggs are deposited in a shallow nest (muskrat lodges are favored in some areas), within decaying logs, or […]
[…]In August, females excavate nesting burrows that may reach 5 or more feet in length. Their 5-30 eggs are deposited at the end of the burrow and are guarded for at least part of the 4-5 month incubation period. Sexual maturity is reached in 5-9 years. Diet Adults are largely […]
[…]well on infrequent feedings (their metabolisms are incredibly slow) of minnows and earthworms, and eggs were produced a few times. One or two clutches hatched, but the tadpoles always expired quickly. Captive breeding was a priority, as they are found only in Lake Titicaca, 12,000 feet above sea level on […]
[…]is acquiring eggs to feed them. Most egg-eaters are too small to take regularly available chicken eggs. Depending on the size of your snake you may feed eggs from pigeons, Coturnix quail, doves, Button quail, or finch. Generally speaking, Coturnix quail eggs (the quail egg eaten as a delicacy) are […]
[…]Brooding Frog Females of this species, missing from Australia since 1985, swallow their eggs, incubate them in the stomach and “give birth” via their mouths! Studying their ability to shut down the flow of digestive enzymes during incubation might have yielded important insights into human digestive disorders. Jackson’s Climbing Salamander […]
[…]insect larvae, snails, crabs, algae and other organisms. The newly described frogs deposit their eggs on the surface of the plant above the water, into which the tadpoles drop upon hatching. The tadpoles, at a mere 3 millimeters in length, are also among the world’s smallest. Other Recent Discoveries A […]
[…]usually occurs in the spring, with healthy females producing multiple clutches of 2-16 eggs each summer and fall. At 82 F, eggs typically hatch in 65-72 days, but a range of 55-85 days has been reported. Hatch rates are invariably high, often approaching 100%. The young average 6-10 inches in […]

[…]actively seek the water’s edge. I’ve experimentally moved water bowls from under hatching eggs and have found that the tadpoles are indeed amazingly mobile on the ground and travel to the water’s edge with surprising speed. Lowering the terrarium’s temperature to 68F for 2 weeks, followed by a period of […]
[…]experienced lizard-keepers and zoos. Egg-Laying Swifts Several of the more popular Swifts produce eggs. Included among these are the Eastern Fence Lizard (S. undulatus), the Western Fence Lizard (S. occidentalis) and the Desert Spiny Lizard (S. magister). Please write in if you would like information on these and other oviparous […]
[…]and Snapping Turtles. Texas Horned Lizard Nesting A Texas Horned Lizard was observed to leave its eggs uncovered after depositing them in the nest hole, apparently to seek shade and rest. During the resting period, the lizard intently watched the eggs – the first such documentation of this behavior. After […]

[…]while far from routine, is possible. Mudpuppies become sexually mature at 4-6 years of age. The eggs are laid individually in a cavity below a rock or log and take 6-10 weeks to develop. The female guards the eggs during the entire incubation period. The larvae are nearly 1 inch […]
[…]eggs. This puzzled me until it was discovered me (not by me!) that the flies lay their own eggs on the shells of reptile eggs – the hatchling maggots are so tiny that they actually enter the egg via the air pores in the shell! It’s not known whether they […]
[…]– Oxytosin and Surgery If your turtle appears to be gravid but cannot seem to deposit her eggs, prompt veterinary attention is necessary. As mentioned in Part 1 of this article, retained eggs invariably lead to infection and, eventually, the female’s death. Oxytosin, a medication used to induce labor in human […]
[…]capsules) on the substrate; females take these into the cloaca with the cloacal lips. The eggs, 30-90 in number, are deposited in the spring. They are attached to the roof of a natural or self-made depression below a rock or log, and are guarded by the female until hatching occurs […]
[…]tend to transform at the same time, and often form huge swarms. Most species mate and lay eggs without feeding, and expire in 1-3 days. This lifestyle renders it difficult to rear Bloodworms in captivity. I did have a colony established for a time in a large zoo exhibit, but […]
