An animal that creates a new anus every time it needs to defecate has been discovered by scientists. The primitive creature, called a warty comb jelly, does not have a permanent orifice for removing waste. The 'transient' anus of the warty comb jelly is thought to be unique in the animal kingdom. But Dr Tamm was unable to find the permanent anus of the Mnemiopsis leidyi. It suggests this feature may have been widespread in the past, but now the wart comb jelly may be the only animal on Earth with this unique ability.
