Divers tend to look for the colour of fish first, but there are A LOT of blue fish out there!
The key to identifying fish is to know the order in which to look at the different features of the fish. First you should note the overall shape of the fish. Is the fish oval shaped or a standard fish shape? Is it elongated in any one direction? Is the fish flattened? Does the fish have a long sloping head or a shorter stumpy head? Then note the location of the fish (is it a bottom dweller or swimming above the reef). How is the fish swimming? Is it using the pectoral fins, caudal fin, or large dorsal and anal fins? Then note any difference from the norm with regards to the shape of fins/body. Lastly look for colour, patterns and identifying marks.
So get out there and look at fish!
Thanks to Sara for drawing the pictures of fish for these blog posts :-)
Happy 2018 everyone!
Firstly, I want to wish everyone a Happy New Year. I hope you all had a wonderful Christmas/Hanukkah/Kwanzaa, and are ready for the year ahead.
As a dive instructor, I am asked all the time what kind of fish people see. I love to help them when I can, but more often than not all people can tell me is "it was black and white" or "the fish was kind of a red colour". Now, I am pretty good at identifying fish and coral, but those descriptions don't really help anyone!
So, I decided to make it a New Year's resolution to help people know how to identify fish, coral, algae and invertebrates. Over the coming year I am going to post not only the most common creatures in Grenadian (and by extension Caribbean) waters, but also how to tell them apart - what identifying traits to look for, what the differences are between individual species of a family, and any interesting information about the marine organisms.
I look forward to sharing my knowledge with you over the coming months.
Stay tuned and happy bubbles,
