Abstract
In this article, we give a representation of -paranormal absolutely norm attaining operator. Explicitly saying, every -paranormal absolutely norm attaining ( in short) can be decomposed as , where is a direct sum of scalar multiple of unitary operators and is a upper diagonal operator matrix. By the representation it is clear that the class of -paranormal -operators is bigger than the class of normal -operators but here we observe that a -paranormal -operator is normal if either it is invertible or dimension of its null space is same as dimension of null space of its adjoint.
