Ecosystems - What Happens When You Put Seawater in a jar, for a year.

A year ago I made this huge natural native saltwater ecosphere in a jar. It has had a lot of ups and downs, but to this day is still very successful. The ecosphere has housed crabs, starfish and a lot more and is currently still housing a lot of crustaceans, paramecium, worms, other invertebrates and even spionid worms.



Netherlands-based YouTuber Life in Jars recounts one year’s worth of tiny activities found within his seacosphere, an airtight closed ecosystem filled with saltwater and sea life.
