Yes, and no. Yes, because all the BIG dinosaurs that were preadators (or prey) did have tails. And no, because bugs were living back then, right? Bugs don't have tails, and they lived in the dinosaur time. (and are still here today)
the answer is no but they can regenerate their tails
YES
no
Yes, salamanders can regenerate their tails and legs. See related link
Missing tails are no cause for alarm; anoles can regenerate their lost tails
Mice should not loose their tails. If they do, than an animal harmed it or the tail got stuck. Mice do not drop their tails like lizards, and mice are mamals, all mamals do not loose their tails
Yes
they grow back because lizards reproduce asexually
Toads live in the forest. Lizards live in the desert. Lizards have tails toads do not.
All lizards can lose their tails by getting it eaten off or something, but some lizards can 'lose' their tails. As in, if you frighten it or catch it by the tail, the lizard could detatch the tail from their body (and it would still move to confuse the attacker), and they could run away and regenerate the tail. =) -kelsey.
yes
Yes, long-tailed grass lizards have the ability to regenerate their tails if they are lost or injured. The new tail may not be as long as the original one and may look slightly different in appearance. This is a common defense mechanism in many lizard species.
