Because the sound would help a predator to localize them.
so they are not attacked
It means they are trying to attract a female or they are trying to drive away a male. Crickets also chirp at certain speeds depending the temperature. For example when it's hot they chirp fast, when it gets cold they slow the chirping. Only the males can do this.
Uh...What book?
Spiders, crickets, other bugs, etc.
Well, you can remove your crickets and you can either get dead crickets or even feed them worms. But make sure you do not get super worms because they have teeth and if one gets out, it could be bad.
Yes - crickets have very little mineral content in their bodies - dusting them with a vitamin powder will ensure your gecko gets sufficient minerals on top of the nutrition the crickets provide. Additionally, feeding the crickets with a varied diet of their natural food will make them a better meal for the lizard.
For your bearded dragon to be healthiest you should feed him crickets meal worms and Romain lettuce. when he is a baby he probably wont eat the salad, and he will eat a LOT of crickets. when he gets older he will cut back on crickets and go to salad. I would not recommend giving him meal worms until he is full grown they can cause impaction in babies.
A poptropica person never gets a fever.
it is unknown but it will probably not happen for a long time
what do i do if unknown chemical gets into eyes
It depends on the age and species of the gecko in question, as well as the number and size of crickets. My adult male leopard gecko gets 5 or 6 large crickets every other day, but I know several other Leo owners give theird 3 or 4 every day instead. As for other types of geckos, you'll have to research that on your own.
