You are right the underwater life is amazing, it is difficult to imagine but some of the fishes have such beautiful colors and you can see them only when you use the light. I love the leopard fish on your video, never seen before.
The mankind have to be careful with our garbage that sometimes cause more harm for those animals living in water, plastic and chemicals.
Thank you for such a nice video :)
agree to that... a lot of beautiful life forms are found under our waters.. and the vast ocean serves us since the start of civilization it is our duty to give back by taking care of it and the life beneath it
