Yes. All animals in the world have muscles, otherwise they wouldn't be able to move.
Banana spiders hibernate when it is cold out, but are not in a very deep sleep. The cold locks up their muscles so on mild days they may come out for food.
Their legs, and the muscles to use these, contained in the thorax (second part in insects, first in spiders and crustaceans).
Rabbits have endoskeletons. That means their skeleton in on the inside surrounded by muscles, tissue, stc. Exoskeletons are on the outside of animals, like spiders.
Yes. Spiders are arthropods and have exoskeletons (the hard parts are on the outside like lobsters, unlike mammals who have hard parts (bones) inside the muscles)
If you mean why are they are not skeletons as a life form then the dull answer is that a living mammal needs a bloodstream and muscles, and tissue and so on. Most insects and spiders are basically skeletal.
Insects, spiders, crustaceans, and anything with an exoskeleton.
No. Fishing spiders are hunting spiders of the genus Dolomedes.
No, spiders can not jump. Yes spiders can jump. It can depend on the spider but most can though. Spiders have large leg muscles like that of a grasshopper, this can help and enable the spider to jump. Spiders aren't known for their jumping abilities though.
Jumpimg spiders, wolf spiders, fishing spiders, cobweb spiders, barn spiders, cellar spiders, funnel spider (grass spider), garden spider.
No. Spiders are not insects. Insects are not spiders.
grass spiders eat other spiders
Spiders have 8 legs. Spiders spin webs. Spiders can walk. I hope this helped
