Red-eyed tree frogs lay eggs on leaves suspended above ponds. When the eggs hatch, the tadpoles fall into the pond, states the University of Wisconsin's BioWeb. Gray tree frogs lay eggs in swamps, ponds and puddles, says Nature Works, a project of New Hampshire Public Television.Know More
During the rainy season, the male red-eyed tree frogs gather above ponds. They vocalize and jostle among themselves to establish territories. When a female appears, the males fight to see which one gets to mate. The winner clasps the female's back. She climbs down to the pond, fills an internal bladder with water and climbs back up into the trees. She selects a leaf hanging over the pond and lays eggs on it. The male fertilizes the eggs. The female then covers the eggs with water from her bladder, describes the BioWeb, a student research project of the University of Wisconsin LaCrosse. The eggs hatch 5 to 11 days later, releasing the tadpoles.
During late spring and summer, male gray tree frogs gather around ponds and swamps. They vocalize and aggressively defend their territories from other males. Females appear to select males based on their calls. The female lays eggs on the surface of any available shallow water. Swamps, ponds, swimming pools, puddles and even water-filled tires are likely locations. The male fertilizes the eggs. The eggs are usually tethered to vegetation to keep them from washing away, says Nature Works.Learn more about Animal Reproduction
Platyhelminthes, also known as flatworms, are hermaphrodites, meaning individuals of the species produce both sperm and eggs. These are released from the platyhelminthes where they become cross-fertilized by other platyhelminthes. Two types of platyhelminthes, trematoda and cestoda, lay eggs constantly. The turbellarian class has a seasonal cycle. Turbellaria also reproduce asexually by dividing. Turbellaria are the only class able to regenerate body parts.Full Answer >
Camels reproduce by copulating during breeding season after the males compete for dominance. After a gestation period of 12 to 14 months, the female gives birth to a calf that weighs up to 80 pounds and that can stand and walk a short time after being born.Full Answer >
All species of crabs reproduce by laying eggs, but the females and males still need to mate to fertilize the eggs. During mating, the male crab carries the female on his back for up to two weeks, after which the female stores the male's sperm in sacs on her abdomen.Full Answer >
Sea scallops reproduce through spawning. Some scallops have male and female reproductive capabilities, while others produce only eggs or sperm cells. During spawning, the scallops release large quantities of eggs and sperm into the water. Fertilized eggs quickly develop into tiny scallops that are suspended in the water like plankton. They soon develop hard shells and spend the rest of their lives on the ocean floor.Full Answer >
