Odd Fish Pics

Again, I’m covered up by work and have little time to write. However, there is always time for images. Today I’ll show you some of my more unusual friends.

This wiggly little thing about the size of a baby’s finger is the Urchin Clingfish (Diademichthys lineatus):

They are quite tiny and constantly moving, so it’s not easy to get a shot. They are also pretty rare. This is the only one that I’ve ever seen.

Okay, this is not a fish. I bet some out there will guess that these are squid eggs:

I have no idea why they are attached to a submerged tree branch which was only about two metres below the surface. It looks like a good lunch for a predator. They are more often seen attached to the underside of rocks.

This is a ferocious Titan Triggerfish (Balistoides viridescens)  which appears to be quite dead. Why is the Monty Python  “Dead Parrot” skit playing now in my brain?Titan Triggerfish (Balistoides viridescens)

You don’t need to weep. This is simply a common habit of the species. They often wiggle-waggle sideways on the bottom in this manner. I suspect that it helps to dislodge parasites.

This cute little guy is a Black-Saddled Toby (Canthigaster valentini):

I see these on almost every dive, but it’s rare to get such a decent image of one. They are very wary and skillful at staying just out of camera range. I surprised this one.

This oddball is a Bignose Unicornfish (Naso vlamingii):

There is another species that has a horn-like protrusion on the nose that looks more unicornish. This one just has a big schnoz. This fish goes through a remarkable colour change when it is at a cleaning station where the little cleaner fish pick off the parasites – like a car wash for fish. Normally the fish appears jet black. However, while it is at a cleaning station, it changes colours until it is nearly a pale baby blue. I imaging that this is to ‘tell’ the cleaner fish that it’s safe to start work and they are not going to be eaten.

That’s all of the strangeness that I can manage for today.
