Crested geckos(R. Cilatus) thrive in a habitat ranging from 50-80% humidity at all times. If a crested geckos enclosure is not providing enough humidity and moisture for the shedding process, in most cases a Crested Gecko will burrow into the most moist spot of the tank. This could be the soil from a planted tank, or even some damp paper towel cramped up in the back. Look over your humidity levels and be sure that they are reaching 75-80% daily for at least three or four hours. To do so, add a couple of extra greens in the set up, provide a tank with peat moss/ coco-husk mix as substrates (this tends to hold moisture for longer periods of time) or simply add a tupperwear container with a hole cut in the lid and filled with paper towels, be sure to mist it daily to keep moist.
A crested gecko will seek shelter in the substrates for two main reasons. One reason is that the animal is seeking a moist area to ensure a healthy shed takes place. Another reason is that during the warmer months of spring and summer, females will lay eggs. These eggs will be laid weather they have been fertilized or not.
No they are arboreals. meaning they live in the canapoy of a rain forest. although they may sleep in a tree hallow or on the ground under a tree root.
Most likely to hide from the sun. I think they're cold blooded, their blood changes based upon their environment, so they cant sit in the sun all day.
They hide under rocks to keep themselves out of the sun at particularly hot times of the day or to hide from predators. Sometimes it's even where they live.
under ground
There are several animals that bury themselves. Lizards, turtles, hedgehogs and the scarab beetle all bury themselves in dirt.
yes they do
Flounders bury themselves to avoid being detected by their prey. They bury themselves in sand or mud and wait until their prey approaches.
No, raccoons do ot bury themselves when dying but may remain in an underground burrow.
Arctic foxes do not bury themselves but they do dig an extensive burrow where they can seek shelter from bad weather and predators.
They bury themselves to protect themselves from predators while they sleep.
yes
Yes they do
The answer to you question both Yes and No ... Dinosaurs are the evolutionary ancestors of both lizards and birds but they, themselves were neither lizards or birds. They were a separate, distinct breed of beast. all to themselves
they camouflage themselves
they just get it themselves
