[…]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 […]
[…]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 […]
[…]the Common Boa (Boa constrictor), are habitat generalists. Reproduction All pythons produce eggs which in most if not all species are incubated by the female. By contracting their muscles, or “shivering”, females can raise the temperature of their clutch by as much as 40 F. With a single […]
[…]fight, and often harass females with near-constant mating attempts. Breeding Three to five eggs are produced at a time, and females may deposit up to 4 clutches per year. Breeding usually occurs between August and December. Females sometimes have difficulty passing their eggs, especially if the diet lacks […]
[…]may reach 2-3 years of age. Breeding Both Sunburst and Green Diving Beetles deposit eggs on live plants. A dip in temperature and shortened light cycle for 4-6 weeks may stimulate reproduction, but is not absolutely necessary. Some have reported consistent breeding following a “drought/rain cycle” (water level is dropped […]
[…]breeding season, another characteristic that endears them to herptoculturists. All deposit their eggs in water. Newts generally spend about half of the year in water, but some exhibit a unique three-stage lifestyle – aquatic larvae, terrestrial sub-adults (or Efts) and fully-aquatic adults. Newts produce virulent skin toxins such as Tarichatoxin. […]
[…]which includes a surprisingly-wide array of creatures. Rodents, rabbits, snakes, birds and their eggs, lizards, frogs, fish, small turtles are large insects have been reported as being taken. I have first-hand experience with impressive biting power packed by most rodents, and find it amazing that Cribos do not utilize constriction, […]
[…]Aquatic Garter Snake (T. c. gigas) approaches 5 feet in length. Aquatic Garter Snakes add fish eggs and leeches to their diets on occasion. Plains Garter Snake, T. radix The emergence of thousands of plains garter snakes from hibernation is a tourist attraction in parts of southern Canada. A toad […]
[…]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 […]
[…]insects that have fallen into the water and carrion are also taken. Reproduction Diving Beetle eggs are attached to aquatic plants. The elongated, aquatic larvae are known as “Water Tigers” and, equipped with out-sized jaws, attack prey much larger than themselves. The larvae pupate on land – in mud at […]
[…]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 […]
[…]females bask far more frequently than do others, and may consume the fetal membrane and infertile eggs passed with the young. Newborn Green Anacondas are secretive and rarely seen; little is known of their natural history. Further Reading You can read more about the research mentioned above in […]
[…]is native or was introduced to control rats (it seems better at controlling chickens and their eggs than rats!). Mammals Guam was home to only three native mammals, all bats. Two have been extirpated by the snake, and the Marianas Fruit Bat is now limited to a single small […]
[…]the sexes, preparation for breeding and egg-laying. The Tadpoles At 80-85 F, White’s treefrog eggs will begin to hatch in 24-40 hours. The tadpoles remain largely inactive for the first 1-3 days, during which time they should not be fed. Once they begin moving about, food should always be available. […]
[…]people report that both species often occur at high densities in certain areas, and that the eggs of many females may be found together. Interestingly, students of mine consistently claim to have observed Rough Green Snakes in abandoned lots in NYC (Bronx), but I have been unable to confirm this. […]
[…]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), […]
[…]at age 3-5. Courting and breeding occurs in May and June, and females deposit 1-4 clutches of eggs (1-15 eggs in total) between May and July. Late-hatching young may overwinter in the nest and emerge the following spring. Captive conditions may alter all of the above, so please write […]
[…]commercial turtle foods are, thankfully, light years removed from the yesteryear’s dried “ant eggs” (actually ant pupae). While natural foods remain important, some remarkable advances now provide turtle keepers with an important safety net, and simplify the process of providing our pets with a balanced diet. Today I’ll review some […]
[…]– 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 […]
[…]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 […]
[…]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 […]
[…]Hooks along the edges of the sperm packet latch onto the female’s genital opening, and the eggs are then fertilized internally. Gestation and Birth Gestation is highly variable, ranging from 7-10 months on average but sometimes exceeding 1 year. It is likely that stress, temperature and other factors play a […]
[…]is an impressive hunter of small fishes and tadpoles (please see photo of a female with eggs, currently in my collection). My nephew readily tackles snakes exceeding his own length, but when I asked him to swim under a dock and capture this spider, he quickly replied “No way, man”! […]
[…]D3 levels are now at normal levels, and several previously-infertile females have produced viable eggs. I’m interested to see if the effects of the bulbs and the sunlight can be distinguished (nothing tops natural sunlight, of course). Several Ringtail Lemurs that share the tortoise exhibit also became very fond […]
[…]early 60’s. I knew enough to bypass the recommended diet of “sugar water and dried ant eggs” but was ignorant of the beast’s UVB requirements. I did, however, gather that it craved sunlight, and during one basking trip the lizard escaped up a caterpillar- laden apple tree where, I hope, […]
[…]spermatophore is picked up by the female’s cloacal lips in typical salamander fashion. Eggs are individually attached to aquatic plants, with the tip of a leaf folded over each egg by the female. The incubation period is short, generally less than 2 weeks. The larvae sport external gills and are […]
[…]Thorny Tree Frog was found in a dense cloud forest in central Vietnam. Females deposit their eggs in water-filled tree cavities, but much remains unknown about other aspects of their life history. You can read the article describing this new species in the article linked below. Brazilian Pterosaur, Caiujara […]
[…]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 […]
[…]You with an Egg Sac As a single mating can result in multiple egg cases, females sometimes produce eggs long after having been fertilized by a male. If you are not aware of a female’s history, you may find yourself with more tarantula-related responsibilities than you bargained for! While a […]
[…]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 […]
[…]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 […]
[…]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 […]
[…]leads to a fatal infection (egg peritonitis). It is important to note that females may develop eggs even if un-mated, and that pets may produce several clutches each year. The 4-20 eggs may be incubated in moist vermiculite at 80-82 F for 55-65 days. Temperament Diamondback Terrapins make […]
[…](72 F by night, 82-85 F by day) initiated in late autumn. Clutches generally contain 5-10 eggs, which may be incubated in moist vermiculite at 88-90 F for 55-65 days. Hatchlings average 11-14 inches in length. Further Reading Python Eats Crocodile: Giant Snake Meals Green […]
[…]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 […]
[…]from the lower jaw! The newly-described Vampire Flying Frog, Rhacophorus vampyrus, deposits eggs in water-filled tree hollows high above the ground, but as yet we know little about the natural history of its most unusual tadpoles. Amazingly, Dr. Rowley also discovered another frog, the Quang’s Treefrog, Gracixalus quangi, and […]
[…]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 […]
[…]are available. Fascinating snakes that specialize in hunting centipedes, spiders, fish and frog eggs and other unusual prey items are also known, but these are rarely kept as pets. A single adult of most species will do fine in a 10 gallon aquarium. Unlike more commonly-kept snakes, they do […]
[…]be watched closely, as males often bite females during courtship. A typical clutch contains 1-5 eggs, which hatch after an incubation period of 95-110 days at 82 F. Please see the article linked below for further information. The Yellow-Spotted Sideneck Turtle, Podocnemis unifilis, This attractive South American turtle commonly […]
[…]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 […]
[…]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 […]
[…]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 […]
[…]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, […]
[…]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 […]
[…]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 […]
[…]Australasian species spend the majority of their lives in water, emerging only to bask or deposit eggs. South American representatives vary in their habits – the Mata Mata Turtle is completely aquatic but others, such as the Twist Necked Turtle (Platemys platycephala), spend some time on land. Depending upon […]
[…]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 […]
[…]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 […]
[…]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 […]
[…]cooling off period at 58-62 F seems to stimulate breeding behavior. Clutches generally contain 5-8 eggs, which should be incubated at 80-82 F for 80-90 days. Handling Individual tolerance of handling varies almost as much as does their color pattern! As with most snakes, wild-caught animals may remain defensive […]
