Crinoids are echinoderms which are closely related to starfish, Sea Urchins and brittle stars. Some of the Crinoids which are found till today have evolved some 420 million years ago. By studying Crinoids, a relation can be established in terms of evolutionary changes that have occurred or have been adopted by the species itself during a certain course of time. Also a relations could also be established to work out the changing climatic conditions since 420 million years ago.

Botox injections comprise Botulinum toxin and is used in the treatment of some kind of eye ailments, like strabismus (crossed eyes) and blepharospasm (involuntary blinking), to treat movement disorders (like torticollis, cervical dystonia) or muscle spasms/stiffness. It can also be used to minimize the cosmetic appearances of wrinkles.

However, due to certain side effects, the drug was ban by FDA, but it has been approved by the FDA for treating spasms of the flexor muscles. Although, there is a scenario that the claim for the application of the drug could be rejected in case of a lack of a medical necessity, that is if it does not fulfil the usual accepted professional medical standards of care.
