do spider have bones

Yup, count them…eight legs with six joints on each. Spiders do not have a skeleton inside their bodies. They have a hard outer shell called an 'exoskeleton'. Because it is hard, it can't grow with the spider.

how long does it take a spider to molt

The molting process can take anywhere from fifteen minutes to several hours. Once your tarantula has emerged from its old skin, it will be extremely soft, tender and sensitive. If you handle your tarantula, do not do so for at least a week after it has molted.

Some spiders have book lungs. A book lung has a stack of soft plates called lamellae. Oxygen in the air passing between the lamellae diffuses through the tissue into the blood. Other spiders have tracheae which are breathing tubes held open by rings of chitin.

Spiders don't have ears - but they can still hear you coming. ... The discovery came as a surprise because, technically, spiders do not have ears. However, the latest research shows that the hairs on spiders' legs are so sensitive that they can detect human speech from several metres away.
