What is the difference between a lady finger banana and a regular banana?

Excuse me, could you please elaborate on the distinction between a lady finger banana and a regular banana? I'm curious to know what sets these two types of bananas apart in terms of their appearance, taste, or any other notable characteristics. Is the lady finger banana a special variety with unique qualities, or is it simply a term used to describe a particular size or shape of a regular banana? Thank you for your time and clarification.
