How many different species of fish do you see congregated around the coral mound in this photo taken while scuba diving in the
Red Sea? I count
at least 9 but, if you zoom in and pan around (which you really need to do to appreciate all the diversity), maybe you will be able to find more. If so, please post your observations in the comments.
The colors and lighting in this scene are a bit subdued because the photo was taken with just ambient light at a
depth of
around 25m (~82 ft). Color correction was applied to the photo, so the image, as seen here, is more colorful than how I saw the scene though my dive mask. However, it is about the same as how I saw it through the screen on the back of my camera, because I had calibrated the white balance of the camera, at depth, using my white plastic diving slate as neutral reference.
Scanning the photo from bottom to top, moving diagonally up the coral from right to left, here are the 9 species I see:
#1: Appearing in the bottom right (but also diagonally up and left of center), we see red fish with large, dark black eyes and white trim on their fins: these are
Pinecone Soldierfish (Myripristis murdjan), and they are generally nocturnal, with their large eyes adapted for nighttime vision.
#2: Immediately in front of the bottom two Pinecone Soldierfish, swimming away from us, is an oval shaped grey patterned fish with a white spot on its side near the dorsal fin. If you look carefully, you’ll see several more of these in the picture, including two that are swimming straight towards us, above and to the right of this fish in the picture. These are
Domino Damsels (Dascyllus trimaculatus) and they have a spot on each side as well as one between the eyes, although the forehead spot may sometimes be absent.
#3: Continuing to move left through the picture we see a gold colored fish, with several more in the scene; these are
Basslets (Pseudanthias sp.) of some sort, and although it is somewhat unclear to me from the photo, these may, more specifically, be
female Striped Basslets (Pseudanthias taeniatus), that despite their name aren’t striped. Or maybe they are the
Lyretail Anthias (Pseudanthias squamipinnis) also known as the
Lyretail Fairy Basslet (in which case I should increase the species count by one, while leaving the genus count unchanged). Regardless of what they are, further above and to the left, you see a red fish with a lateral stripe and pink dorsal, caudal, and anal fins and belly. These are assuredly
male Striped Basslets (Pseudanthias taeniatus) that are striped per the advertising in their name.
#4: Continuing up and to the left, we see a light colored fish, swimming away from us, with dark eyes and dark edges on its caudal fin (and with a couple of these also seen in the distant background): it’s a female
Zebra Angelfish (Genicanthus caudovittatus). The males of these fish have dramatic vertical stripes (hence the ‘Zebra’ in the name), but the females are relatively plain, as seen here.
#5: Closest to us, facing to the right, and also seen in the upper left corner of the photo, is a dark colored fish with white caudal and pectoral fins. I believe it to be a
Yellow-edge chromis (Chromis pembae), although the yellow accent on the dorsal fins is not evident in this photo.
#6: The centerpiece of this scene, the large reddish, spotted fish with subtle vertical stripes is a
Coral Grouper (Cephalopholis miniata). They can grow to 50 cm (~ 20 in), which this one is probably close to in length based on the expected sizes of the other fish in this picture.
#7: Below, to the left of the Coral Grouper, we can see a couple smaller fish with yellow highlights on the forehead and orange-accented forked tails. These are
Miry's Demoiselle (Neopomacentrus miryae).
#8: Just behind the mouth and tail of the Coral Grouper, are two different
Crown Butterflyfish (Chaetodon paucifasciatus), with their vertical black and yellow stripes and bold orange accent in front of their caudal (tail) fin. If you want to see a much better picture of one of those, see my earlier post:
https://plus.google.com/103568923622435206188/posts/a6djQ6NNecK #9: If you look carefully just below the top left corner of the coral mound you’ll see a fish that is light colored in the back and brown in the front. Although, according to the Encyclopedia of Life (
http://eol.org/pages/209021/names/common_names) its preferred common name is the
Two-tone Puller (Chromis dimidiate), you can understand why some also call it the
Chocolate-dip Chromis.
So that’s my list. If you find others or have suggested corrections, please put them in the comments.
Now, I started this post stating this photo was taken at a depth of about 25m, but how did I know that? Well, as it turns out that
only 45 seconds before taking this picture, I happened to have
snapped a picture of my dive computer display which read a depth
84 ft (~25.6 m), and so I figured that I must still have been near to that depth when I took the photo.
But, then, I became intrigued with the question of
whether the diversity of fish in the photo could also be a clue as to the depth, and so using data found at the Encyclopedia of Life (
http://eol.org), I looked up the habitats, which has the depth at which they are seen, for each of these nine species. Here are the results:
1) Pinecone Soldierfish (Myripristis murdjan) 1-50m
2) Domino Damsels (Dascyllus trimaculatus) 1-55m
3) Striped Basslets (Pseudanthias taeniatus) 10-30m
4) Zebra Angelfish (Genicanthus caudovittatus) 2-70m
5) Yellow-edge chromis (Chromis pembae) 25-50m
6) Coral Grouper (Cephalopholis miniata) 2-150m
7) Miry's Demoiselle (Neopomacentrus miryae) 2-25m
8) Crown Butterflyfish (Chaetodon paucifasciatus) 4-65m
9) Two-tone puller / Chocolate-dip chromis (Chromis dimidiate) 1-36m
Certainly this is a wide range of depths, but
if you intersect them all, you get 25m, which is very close to what my depth gauge reported less than a minute earlier.
Maybe a coincidence, but a good one! This scene was captured while scuba diving in the
Red Sea at the Paradise dive site in
Eilat on July 2, 2014. As mentioned above, this photo was taken at about 25 m (~82 ft), but the deepest point of the dive overall was slightly deeper, down to 29 m (95 ft).
