Fish ID :: Where to Start

When I first started diving, I was blown away by the number of different creatures in the ocean. It was exhilarating seeing so many new animals, but also overwhelming because I had no idea how to talk about them – either underwater (a finger pointed at “that one”) or above the water (“the fish under the rock that was kind of blue but with the stripe about halfway down and the grumpy face”).

The beginning of wisdom is to call things by their proper name - ConfuciusChris had been diving for a while already and I felt very behind in my ability to talk coherently about what I had seen on our dives, not to mention totally dependent on him to fill out my logbook with any type of accuracy.

I started trying to teach myself (lowering my aims pretty quickly from Every Fish in Every Ocean to The Fish I Am Most Likely to See), but even at a beginner level, I struggled to find good resources that would help a newbie diver (or scubi newbi, as I will henceforth call them) gain this knowledge on her own. I relied almost exclusively on experienced divers to either tell me the name of a fish or point me in the general direction where I could start my hours-long web search. This is how everyone seems to learn this stuff; go on a dive, find something weird and ask the guide about it.

While it’s great to learn from experts (and obviously really helpful), there are two things I don’t like about them being my only source of information: 1) Guides can be wrong – sometimes just a little wrong but others incredibly wrong (at least for someone like me who is a fiend for accuracy). 2) Having someone tell you the name isn’t as helpful (or, for me, as memorable) as having to figure it out based on your own logic, reason or study.

Ever the dedicated, over-achieving student, I wanted to learn how they knew it was the fish they told me it was. Surely if I learned their logic I could start to figure these things out for myself and not need them to tell me, right? Right.

A while back, I decided to make a little outline, initially just for myself, that would help me learn how to identify the fish I was seeing on our dives. That grew into an idea for a fully-fledged course that could help other scubi newbies (it’ll catch on, I just know it) feel more knowledgeable about the creatures they start to discover. It’s the resource I really wished existed when I started diving myself.

So without further ado, may I present our Fish ID Course!

The handy ocean-blue button below will take you to the Basics page, where we look at the two key elements that make a fish a fish. From there, you’ll move on to individual snapshots of the most common reef fish and how you can easily identify them while you’re diving, snorkelling, watching a nature documentary or visiting an aquarium (though their little signs are usually pretty helpful). Casual visitors can dip in and out for whatever morsels they find useful, while more dedicated academics can challenge themselves with quizzes and puzzles.

I sincerely believe there’s something here for everyone, diver and non-diver alike.
