Do dragonflies lay their eggs in water and spend their adult lives on land?
Yes, adult female dragonflies lay their eggs in or near water but live on land.
there are many different types of water-borne insects, including those that spend all of their lives in it and others that live only their lives as eggs and larvae there. A few of the former are commonly known as backswimmers, water boatmen and giant water beetles, while some insect larvae living in water are mosquitos, dragonflies and damselflies.
Frogs and toads are amphibians, which means they live their lives both in water and on land. Typically, frogs breed and spend their juvenile (or "larval") stage in the water, then spend some or virtually all of their adult lives on the land. Frogs and toads are distinguished from salamanders (which are also amphibians) by the fact that adults do not have a tail.
Toads spend a large amount of their adult lives away from water, but must return to it to breed. The eggs and tadpoles remain in water. +++ They spend most of their time hiding away in cool, slightly damp places such as under fallen trees and rocks in nature, and beneath garden-sheds and behind wood-piles in gardens. (My neighbour and I share our gardens with a small colony of frogs, and these too spend a…
Many forms of insects spend their immature stages in the water as larvae and nymphs. Among these are dragonflies, damselflies, mayflies, mosquitos, midges, gnats, and scorpionflies. There are fewer adult insects that have adapted to an aquatic environment. Among these are some beetles and true bugs such as: the whirligig beetle and water strider, respectively.
Yes. A dragonfly larva lives in the water, feeding on small animals from water fleas to stickleback, and breathes through gills at the back end. To become an adult it climbs out of the water and molts into the winged form. You might have seen the larval skins on rocks and plants at the water's edge!
No. The amount of time that adults spend in the water varies enormously. Bullfrogs and green frogs, although they have lungs and breathe air, spend almost all their adult lives in the water. On the other end of the spectrum, toads and treefrogs spend the majority of their adulthood outside of water. All frogs and toads, however, must eventually come back to the water to mate and lay eggs.
Is it true that Animals with backboned that live part of their lives in water and part on land are called amphibians?
Yes, the standard definition of an amphibian is a vertebrate animal that lives part of its life (usually the developmental/childhood portion) in water and part of its life (usually the adult portion) on land. However, this isn't always a clear distinction - many amphibians such as frogs will spend their whole lives around and in water, but gain the ability to stay on land as an adult.
Short answer - Yes. Frogs are amphibians that spend large portions of their lives in aquatic ecosystems. The entire developmental phase of frogs takes place in water itself from when the frog emerges from the egg, though morphing from a tadpole to a mature adult frog. During adult-hood, frogs spend time in water and on land, the amount of time depending on the species of frog.
While young, dragonflies spend their lives underwater as nymphs. These gradually grow and develop wingbuds before climbing out of the water and undergoing a final moult to become the winged insect. The nymphs are one to two inches long, have six legs, large eyes and a hinged jaw which they can shoot out to catch their animal prey. They are able to walk on the bottom but are also able to move rapidly by a…
It depends on the insect. Some insects such as mosquitoes/dragonflies/damselflies can spend their larval stage in the water of ponds and streams. Adult forms of insects such as ladybugs will seek shelter under rocks, loose bark on trees and inside the walls of houses. Other insects such as Monarch butterflies can fly hundreds of miles south to spend the winter in Mexico, and return back to the U.S. next spring.
Dragonflies are insects and during their larval/nymph stages they live for several years in/on the bottom of freshwater pools or lakes. Here there may be many of them but they live as individuals. Come summer and the mature nymphs crawl out of the water and transform into adult dragonflies with wings. In this stage they are predatory flying insects that again live alone. However, during the adult phase they will couple and mate with another…
No. Though they do spend a lot of time in the water, they are reptiles. Amphibians lay their eggs in the water, and reptiles lay their eggs on land. Alligators are not amphibians. They are reptiles. Amphibians are animals that begin their lives in water and have gills, and spend their adult lives on land and have lungs. No, an alligator is a Reptile. A good way to tell a reptile is reptiles have scales…
