no they don't.
Yes they do. Scorpions and spiders shed their entire outer skin in one piece.
yes spiders do
Cicadas shed their skin because they are insects. All insects shed their skin. It is called molting. An insect goes through several molts before it becomes an adult with wings. Cicadas simply climb trees and then shed their skins. They are easier to find. Not only do insects spread their skins but so do spiders and crabs. Some snakes shed their skins and some birds shed their feathers.
It depends what kind of spider. For instance, I had a pet tarantula, and he did molt. That means shedding his skin. That's about all i know in this subject.: )
they shed every 20 years
Spiders shed their exoskeleton through a process called molting. They produce a new, soft exoskeleton under their old one, then they split open the old exoskeleton and crawl out of it. The new exoskeleton will harden and provide room for the spider to grow.
Spiders have an exo skeleton, their "bones" are on the outside. No. they would not have a spine. although when some spiders molt, or shed their skin, and old exoskeleton. This enables them to grow.
i dont no
all cells die. when human skin cells die, for example, they are shed and we call it dust.
They regularly shed their skin its quite irreagular for them to shed skin though..
salamanders are AMPHIBIANS. not reptiles. even so, they do shed their skin several times during their lifetime - its more shows them as healthy and growing than close to death.
Humans do shed skin. When skin cells die, it falls off your body it's called Desquamation. Every hour nearly 40,000 skin cells are shed, and it takes one skin cell about a month to complete the desquamation process. In fact, person from 2009 that says humans don't shed, the dust in your home is mostly dead skin cells. Your dead skin literally falls off your body.
