Wildlife Spotting

It's 'normal' to see the occasional dead fish or crab, most of them Leftover Lunch from birds or left behind by fishermen. This was one of those 'what the heck happened here' moments though :/

I think I found it. Arabian Gulf Catfish (Arius Bilineatus) Maybe all those guys ran out of air, we had a big pile of green algae at those beaches the last few weeks. It goes along with a bigger skeleton we found at last weeks beach clean-up: http://en.wikipedia.org/wiki/Ariidae

I just checked (didn't see the Latin name you provided - had another coffee and it worked ;-)) That one could well be it, from seize and all (found this link here: http://www.scotcat.com/bagridae/mystus_tengara.htm). But that swarm would have been way off from the region they normally appear in.

I thought about catfish too at first, but see the spikes on the second fish from the right? Those were solid. You could pierce your finger with them. Or could that be from the first fin, just that the fin disappeared while drying up since they are so small?
