Im not sure if this post is OK for this Forum. but i just seen one of the best Ocean Reef Documentary, I am not promoting any YT channel. so i will not give the channel name. But it is just an amazing bit of footage. it covers from coral to fish to Nudibranchs. it was just amazing.. after seeing this Doc i have a new love for the Nudibranchs they are some of the most Beautiful creatures under the sea
