Yikes! Creepy.
I kinda miss them....Yikes! Creepy.
Lol.Yeah, saltyfilmfolks is 100% right on the id. Also, the original subject of this thread made me legitimately laugh out loud.
I'm still going with aliens.Nevermind the bryozoan thing. I correct my mistake and have found a positive ID. The growths are a protist called Labyrinthula that act as commsensals, mutualists, and pathogen. Now it only gets crazier from here. These guys can use algae (mainly chaeto; which they act as a mutualist), sea grasses (pathogen), and sea stars(pathogen) as host. In fact the devastating "Seastar Wasting Disease" is caused by these things. Now in reef tanks they shouldn't possess much of a problem thankfully (unless you plan to keep seagrass or coldwater sea stars). The reason that they move around is how they reproduce. They kinda just break off some cells and send them off into the water column where they eventually settle onto something . The filaments are how they move around short distances.
