You can reduce the highlights at the top left corner. Otherwise nice image...

Agree about the highlights. Good capture with the tentacles (or whatever) out.
Thanks for sharing.

Very interesting, but I feel it is not entirely sharp. Also the composition seems cluttered. You can use a higher ISO here for a faster shutter speed.

Nice photograph. The details and pattern are interesting. Wish that structure on the left was not present, it is a bit distracting. A vertical composition might work.

Thanks for sharing.

Nice interesting shot Vishal.

I googled it. The tentacles which Abhishek is saying, are called a Cirri. Single thread is called as Cirrus. They might be used for movement or for catching pray.
These creatures stick with the rock or coral with this elongated goosed neck which is also called as stalk.
