[…]take this into their cloaca (reproductive opening) and fertilization occurs internally. The eggs are laid in compact, jelly-covered masses that are attached to twigs, plants or sunken logs. Each mass contains 50-160 eggs. The sight of 20 or more large, brilliantly marked salamanders writhing together in as they vie for […]
[…]body, the female scrapes together a pile of rotting leaves and other vegetation, into which the eggs are deposited. Some construct a two-chambered nest, with the upper chamber serving as retreat for the female, while others merely coil on top of the leaf pile. The female guards her 20-60 eggs […]
[…]Setup Snapping turtles are entirely aquatic, rarely bask and usually leave the water only to lay eggs. Hatchlings and small turtles are best kept in water of a depth that allows them to breathe by extending their necks to the surface. They mainly walk about the bottom and are not […]
[…]longer. REPRODUCTION In my experience, most females in NYC and the immediate environs lay their eggs on rainy nights in early June. I am always rewarded by the sight of nesting females on such nights and during the following mornings. If you have a chance to visit nesting sites during […]
[…]to induce egg laying. Odder still, however, was the fact that a male placed in the tank with the eggs (and without the female) on the following day fertilized the eggs. He was in breeding condition, as evidenced by the rough “nuptial pads” along his forearms, and perhaps was responding […]
[…]have quite complicated reproductive behaviors, and exhibit a high level of parental care to their eggs and tadpoles. I will address this topic in a future article. An article with natural history details and information on the care of blue dart frogs in zoos is posted […]
[…]tended by the male, and sometimes by the female as well. Males soak in water and then lie over the eggs to moisten them, and may tend several clutches at once. The eggs hatch in 14-18 days and the tadpoles are transported to streams on the back of either parent. […]
[…]on the Venezuelan llanos. In many different animals, sperm can remain alive and able to fertilize eggs for years to come. Queen termites mate once and somehow produce fertilized eggs for up to 20 years after! Further information concerning research with this species at Wollongong University is available […]
[…]had it been overcome, eventually escaped. Reproduction Mating occurs from March to May, with 6-30 eggs being laid 27-28 days thereafter. Second clutches, laid in August, have been reported in captive situations but not in the wild. The eggs are secreted in cavities below fallen trees and rocks, or within […]
[…]of water. The substrate should be placed within a small Tupperware or similar container and the eggs half-buried into the substrate. Weigh the container, with substrate and eggs inside, and note this figure on the container’s lid. Re-weigh once each week – any drop in weight is the result of […]
[…]male frogs in the wild are being found to have inter-sex characteristics, including immature eggs within the testes. A recent Harvard University study found such characteristics in 21% of the male green frogs, Rana clamitans, in ponds in suburban Connecticut. It seemed that the affected frogs were more common in […]
Spring in the northeastern USA is prime time for amphibian watchers. Its arrival is most noticeably announced by frogs – first by spring peepers, Pseudacris crucifer and wood frogs, Rana (Lithobates) sylvaticus, with a succession of others following close behind. However, the season’s earliest greeters are silent. I have observed […]
[…]beetles, spiders, grasshoppers, caterpillars, mice, shrews, voles, ground nesting birds and their eggs, small snakes, lizards and their eggs, and carrion. Averaging 2-3 feet in length, exceptionally large specimens can top 4 feet. Glass lizards, as their name implies, quickly autotomize (shed) their tails when handled or captured by a […]
[…]with enthusiasm! Male African bullfrogs are diligent parents – they defend the eggs and dig channels to bring water to their tadpoles. You can learn more […]
[…]survive in Madagascar’s forest canopy, reached 24 inches in length. Geckos generally lay 2 eggs, although some bear live young. Arboreal types often glue their eggs to tree branches or building walls. Most are insectivorous, but many take nectar and over-ripe fruits as well. The voracious tokay gecko, Gekko gecko, […]
