I need to know about animals that reproduce without mating.?

Question

I need afew examples of animals that reproduce without mating and how it happens -school research- Thanks!!!

Sorry without the question mark at the end, oh and i need it as soon as possible!

Answer 1

Well first off.. they miss out a lot

There are several ways that this can happen

1) Consider the lowly flatworm or the starfish. If you cut them up and leave sufficient material the pieces will grow into a complete adults. No sex involved whatsoever. This is re-generation to the extreme

2) Consider some animals which have BOTH male and female organs. Lots of insects have this ability. These creatures simply generate offspring, or eggs, or whatever. Hermaphroditic conditions can derive normally or can also be unique (ie a twin that is 'absorbed' in the womb).. The link below is for a Hermaphroditic Deer that was recently shot (prob. near a nuclear power plant.. its worth reading just to be able to say "no way...!")

3) Lastly there are animals that can CHANGE their sex and to some extent facilitate reproduction in this manner. For example, in a population of mostly male fish some will actually change into females. (wierd eh? - go to bed as one thing and wake up as another.. sounds like a bad 'B' movie doesn't it).

hope that helps....

Answer 2

Aphids, water fleas (little zooplankton critters), and some contributors of maximum animal communities can reproduce parthenogenetically (cloning the mummy). no longer mammals. The offspring are all similar women human beings to the mummy...yet they have 0 variability and are very liable to environmental replace. it truly is why aphids do this contained in the spring...popping out clones of themselves. Then, later contained in the 365 days, even as predators are out and food is extra sturdy to get they start up making men, mate, and make eggs that would very last over the iciness. each thing is wonderful cloning your self till circumstances get difficult, then its time to make men and party! contained in the paper this morning....first evidence that sharks can do this, a hammerhead cloned herself captive in an aquarium.
