The Sea Crown consists of a bioluminescent translucent bladder held together by its small stalks, having yellow and green patterns running along the top. The stalks holding the Sea Crown's bladder are bright green, yellow-tipped in color.
This plant consists primarily of a large bladder-like sack containing a huge variety of bacterial species, which may enable it to break down complex compounds it draws from the root system. Shares large sections of genetic code with the membrain tree. Environment scans indicate this plant is rare to the point of extinction.
