Is this an alien egg?

[DmitryB]

I got small batches of ocean live rock from a few places to diversify my tank's biological portfolio. The rocks came from Gulf Live Rock, Marco's and Tank Stop. I don't know which rock this is, but it's got these... pods on it. Big and squishy. You can see they flap in the flow. It may be some sort of plant life. Or it's an egg from the movie Alien. Anybody have any idea what this is and if it's reef safe? (It's a bit dark, I don't have lights on my new set-up yet.)

I am pretty sure they are sponges.

They're pretty ugly! Anybody eat those?

No one has in my tank. I left them... You will likely have things growing on the rock in front of them down the road that will cover them up.
