Are you a diver yourself @vcelier?
I love diving and have done it many times in Thailand and in Maldives. Have seen all the sealife you mentioned except probably the zebra shark.

It is amazing to see this wild underwater life for yourself. It is just like visiting another world on our planet Earth :) Would recommend everyone to try diving.

By the way, @vcelier. I don't know if you are aware, but me and my team are developing a completely free mobile app for Steemians called SteemApp which will allow users to post and browse through feed much easier from mobile phones. Would love if you would consider voting for us as witness on yuriks2000 account. Will really help us develop quicker and more apps for Steemit. Thanks
