No they just have toxins for defense but not enough to kill a human
I wouldn't. Its not safe... If they're toads you want to mix with the fire belly then make sure they are the same size..keep in mind that if they are different sizes..they can get REALLY mad because either toad would be on the others "property" and if that happens they will kill each other. I wouldn't get into the fire belly toad/frog issue..just DONT mix them. Hope I helped! :)
no
Yes IF - you have enough water so the toxins from the toads don't kill them - the fish can survive in the same temperature range as the toads - the fish are going to eat or nip at the toads -the poison will not kill or make the other fish ill at contact such as a healthy Betta fish. Lots of people keep feeder guppies with their toads. Sometimes the toads catch them. But is very rare. Mine didn't catch them.
by them destroying toxins (by wanking)
No you cannot kill someone by poking them in the belly button, that is a myth. The only way that could happen is if they Had a Hernia in their belly button and you ruptured it. If you stabbed them or shot them in the belly button it could possibly kill them. However a simple poke or twirl in their belly button will not harm them. A hard poke would hurt, but it would not be fatal.
The toxins which are built up in food chain are the toxins which consist of heavy metals such as led, cadmium, mercury. since most of the agrochemicals contain these heavy metals, they tend to accumulate in the food chain. Once a heavy metal get into a body of an animal, it will be deposited in fat tissues thus it cannot be eliminated therefore with increase intake of those heavy metals ,more and more heavy metals accumulate in the food chain. Apart from those toxins food cantain naturally occurring toxins as well.
In a few marine species, gray cells of the sponges primitive "immune" system and can release toxins that kill all cells in the area as part of the rejection of foreign material.They also produce toxins that prevent other sessile organisms such as bryozoans or sea squirts from growing on or near them.A few species, such as the Caribbean fire sponge, cause a severe rash in humans who handle them and such toxins may protect against predators.The Caribbean chicken-liver sponge secretes toxins that kill coral polyps, allowing the sponges to grow over the coral skeletons.See: http://en.wikipedia.org/wiki/Sponge
Yes, via bacteria such as salmonella or toxins such as botulinum.
No, some toxins only cause illness and don't normally kill except in cases if high levels of exposure. Whether a toxin will kill or not also depends on how much a person is exposed to.
yes, fire does kill a vampire. i don't know how or why but it does.
No, he would never kill an animal
