[bckane]

[ahoyhoy239]

what the...i definitely want to see what made that

 

[bckane]

[jessp]

almost like a tube anenome hole.

 

[ReefWreak]

Is it a sponge, or is it sand, or is it hard?

 

[Fish2reef]

That is neat never seen it before, the sand is a lot thinner from the surrounding provably all the way from the bottom glass.

If you haven't seen anything come out of the hole I suspect it is a nocturnal creature.

It's Friday night.
Pull up a chair, have a red lens flashlight on hand, lots of beer or alcholic beverage of your choosing and camp out for the night. I'd bet you'll know by morning what made it.

1. wasp nest
2. cooling tower for a nuclear reactor
3. vent leading to the Morlocks' underground Eloi processing plant
4. OK, I have no idea, probably some kind of tube worm
   [/list=1]
   
   I like coralfragger's idea though, make a night of it. Try offering it some pretzels. Oh that's right, they'd float.

thats crazy!

 

[Ludwigia73]

I've seen those on the grass flats... still not sure what made them. Taggin along, waiting for an answer!

 

[Rogger Castells]

my guess is either the energizer bunny or the chupacabra!
Brian you better get some video footage of this creature, taggin along too

 

[bckane]

Im off to work now.....just checked with the flashlight still nothing in the hole.....will post back in the morning

It's an egg mass from some type of gastropod. We covered in it in one of my marine bio classes, but I don't remember for sure which one. If I remember, I'll post

I'm betting on the chupacabra.

 

[Young Frankenstein]

"choupakabrious dondilakis" or hole maker, known for the round egg mass holes it builds before the feeding frenzies , feeds mainly on SPS and LPS corals.

 

[bckane]

Im thinking chupacabra also
