U/W Pictures 4:

An enormous Rainbow Parrotfish Scarus guacamaia

Just like our own Blackfish, large adults do not like to be approached. The small fish at the lower left is a Schoolmaster Lutjanus apodus.

With the 1/2 second shutter lag of the digital camera you could never
deliberately set up an action shot like this. This is a happy accident.

(c) Rich Galiano
This school of Angelfishes was so intent on devouring this big
Basket Sponge Xestospongia muta that they took no notice of me.

(c) Rich Galiano
All I had to do was swim up current, and snap away !

(c) Rich Galiano
This one is completely upsidedown.

 

(c) Rich Galiano
Thimble Jellyfish Linuche unguiculata
Normally, red jellyfish are the kind you don't want to see
but these little ones didn't seem to sting at all.

(c) Rich Galiano
Sand Tilefish Malacanthus plumieri

There aren't too many places in the tropics where pure white is actually camouflage. Related northern Tilefishes live much deeper, beyond the range of divers.

(c) Rich Galiano
A small coral head with a Tobaccofish Serranus tabacarius,
a kind of basslet, in front of a Giant Tube Sponge
Aplysina lacunosa. Black fingers in the background are
probably Common Bushy Soft Coral Plexaura homomalla.

(c) Rich Galiano
Nearly the same scene, with the fish moved around.
Add a Chromis and some Damsels.

(c) Rich Galiano
Sargassum Triggerfish Xanthichthys ringens
The three stripes on the cheek are the best identifying mark,
as the colors are otherwise variable.

(c) Rich Galiano
Porkfish Anisotremus virginicus

(c) Rich Galiano
Another Stoplight Parrotfish, with glorious colors.

(c) Rich Galiano
The fearsome Damselfish again.

Defending its turf.

(c) Rich Galiano
I get no respect. Who named these things, anyway?

Unlike most reef fish, which eat the coral directly, Damselfish are farmers. They clear off a small patch of reef and grow algea on it, which they then feed on. They will defend their patch fearlessly - I have actually been bitten ! ( It didn't hurt. )

Queen Parrotfish.Scarus vetula
Eatin' coral, and poopin' beach sand. Yep.

Most of the fishes on the reef actually feed on the coral, gnawing on it all day, every day. One thing that you can deduce from this immediately is that coral must be a lot more resilient than some hysterical ecologists* would have you believe.

Does this mean it's ok for you to go bashing into it? Hardly. Always try not to touch or break the corals and sponges you see, but if you occasionally have to put a finger or two down on something solid, don't lose too much sleep over it.

I try never to touch anything on the reef because I don't know offhand which things sting and which ones don't, and some of them can really ruin your day !

* Not all ecologists are hysterical.

A brilliant Blue Tang. Photo is completely untouched.

(c) Rich Galiano
Featherduster Worm Sabella

(c) Rich Galiano
My best guess is that these are baby Princess Parrotfish
Scarus taeniopterus, about 3" long.

(c) Rich Galiano
Ocean Triggerfish Canthidermis sufflamen with Bar Jacks

(c) Rich Galiano
Fire Worm Hermodice carunculata
Notice the tufts of white bristles underneath.
Leave this critter alone.
