Light bulb tunicates (Clavelina huntsmani), named for their bands of pink internal organs that resemble light bulb filaments, are a social species of tunicate (or more adorably known as “sea squirts”) that reproduce asexually so what you see here are red algae surrounding a little cluster or sea squirt clones! Spoooooky!
