Floating Anemones

Hey everyone, over the past month our iNaturalist contributors have more than tripled! We are all so grateful and excited to see what you find!

This week I wanted to talk about one of the less well-known creatures that live at the ocean’s surface, the floating sea anemones. These anemones are in the genus Actinecta and they don’t have a common name, they are only referred to as their scientific names. These creatures have a float at their base that allows them to live at the surface of the ocean, hanging upside down and catching prey with their tentacles. They are a pretty rare find but sometimes they can be found in the open ocean or washed ashore.

Happy Halloween weekend!

Never heard of these. Are they confined to the North Atlantic?
We have not seen them on our projects: https://www.inaturalist.org/projects/blue-community-s-afr
From what I can see they are quite localized; https://inaturalist.org/taxa/1210955-Actinecta

Hi Tony! They are not commonly found, therefore their exact distribution is unknown but they are more commonly seen in the Southern Hemisphere.

I had never heard of these until today, because I got stung by one! I was just taking photos of a scorpion fish when I felt a painful stinging on my upper lip and also my cheek on the other side, and on the way to the lifeguard, I could feel it swelling up more. Got antihistamines and hope in a day or two it'll go down.

Not once in my 5 years of snorkeling and skindiving (I go nearly every day, I live in the Canary Islands) has this ever happened, hell, I didn't even know they existed! 😚
