SmolReef Posted July 25, 2019 Share Posted July 25, 2019 Anyone know what these are? Recently got some live rock from KP aquatics Quote Link to comment
johnmaloney Posted August 15, 2019 Share Posted August 15, 2019 Looks like a tunicate, there are so many and ID sources are so slim that a species level match would take a lot of time or some luck. Possibly a Rhopalaea species, when you google it you will see only the attractive ones divers photograph, but if you search Rhopalaea abdominalis you will see not all species in the genus are beautiful and blue. 1 1 Quote Link to comment

Tired Posted December 29, 2019 Share Posted December 29, 2019 Oh, cool! You got a big one. Here's something interesting for you. That light green sliver, Chordata, contains all chordates. Chordates are animals that, at some stage in their life, have a notocord. Essentially, a simple spinal column. The animals that have notochords are lancelets, all vertebrates, and tunicates. Tunicates start out with a notochord, a brain, a heart, all manner of organs, but then glue themselves to the substrate and become a bag of nothing. Our closest non-vertebrate relatives are a weird boneless fish-creature and a bag. 4 Quote Link to comment

Here is a weird one with a very visible anatomy that is hanging out on the acrylic of the hermit tank 4 Quote Link to comment
