What is a Aboral in anatomy?
The main axis is heteropolar—i.e., with unlike ends, one of which bears the mouth and is termed the oral, or anterior, end, and the other of which, called the aboral, or posterior, end, forms the rear end of the animal and may bear the anus. The main axis is hence termed the oral-aboral, or anteroposterior, axis.

What is the difference between oral and Aboral surfaces?
One is the oral surface, where the mouth is and the tube feet project. The tube feet on the oral surface are limited to distinct regions called the ambulacral regions. The other surface is the aboral, which typically contains the anal opening of the digestive system.
What is the function of the Aboral end?

Can starfish hurt you?
The answer is no, starfish are not poisonous at all and their spikes can't hurt you unless it pierces your skin – or if the spike has a venomous substance on them which only happens in some species of sea stars like urchins.
