Yes you heard if folks, I'm taking reef geekeness to the next level

so if you have any interesting looking sponges or you know what species they are let us know. Here's a few of mine weird looking and if you know what type they are let me know. This first one looks like something out of Alien, it's got arms stretching out kind of keeping it secure. Next are these black one's fairly common I think but don't know their names. The last one is hard to make out but it's yellow.
