FishBase is ‘a Global Information System on Fishes’. I use this website to determine the common name and alternative names of fish.
The aim of the World Register of Marine Species (WoRMS) is to provide an authoritative and comprehensive list of names of marine organisms. I use this website to check if the scientific names I use in MyFishGallery are (still) up-to-date. Due to new insights it can happen a scientific name will change.
I did my Divemaster education at Sunshine Divers in Koh Tao (Thailand). If you are interested in a professional diving career I can recommend this dive center. They have a personal approach and they do small group courses. You will be taught by Natalie Hunt, an experienced Course Director.
Sunshine Divers also offers non-professional dive courses and fun dives.
