Sea Crown

The Sea Crown is the rarest type of harvestable flora in Subnautica, with only a small number in existence. Overall, it is the second rarest type of flora in Subnautica, behind the Giant Cove Tree. It is found exclusively in the Bulb Zone, the Dunes Sinkhole, and certain Grassy Plateaus Caves.

By cutting the plant with a knife, the player can harvest Sea Crown Seeds.

Appearance
The Sea Crown consists of a bioluminescent blue 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.

Trivia

 * The Sea Crown resembles a Portuguese man o' war, which is itself a composite lifeform.
 * Originally, only two Sea Crowns existed, located in the Bulb Zone. However, the population is much larger now.
