A Totally Enclosed Ecosystem

The Inside Story

Inside each EcoSphere are active micro-organisms, small shrimp, algae and bacteria, each existing in filtered sea water. Because the EcoSphere is a self-sustaining ecosystem, you never have to feed the life within. Simply provide your EcoSphere with a source of indirect natural or artificial light and enjoy this aesthetic blend of art and science, beauty and balance.

30 Years of…

The Original EcoSphere® is the world’s first totally enclosed ecosystem – a complete, self-contained and self-sustaining miniature world encased in glass. Be wary of inferior and lower quality imitations. Easy to care for, an EcoSphere is an incredible learning tool that can provide powerful insights about life on our own planet… and provide a glimpse of technology that’s shaping the future of space exploration.


This isn’t a complaint or anything, but how long are these shrimp supposed to last? I bought one for my daughter when she started Middle School. She’s finishing her sophomore year at Harvard and the shrimp is still alive.

Two of my shrimp have been living since 2002! They are almost 9 years old and still doing great. The people at ecosphere know what they are doing.

I just wanted to share with you that my sister purchased the Small Pod 5.25″ ecosphere serial number 54794 back in October 2997, so that was about 15 1/2 years ago, and she had it sent to our family and we still have one shrimp that is alive. I find that rather amazing and we have watched this ecosphere onver all these years and still watch with interest that this one little shrimp is still alive. Our children were not real young at the time, our youngest was 17 when this was shipped to us but our family has watched this pod with interest over the years. It pretty much stays in the same spot on a shelf and in fact we will go for a long time and just about forget it and then we will look in and sure enough that one little shrimp in still alive. I just found the EcoSphere Handbook the other day and checked the pod once again and the shrimp is still alive and the handbook says it was issued October 1997 and I was just amazed that we have had it that long and one is still alive. I just wanted to drop you a note and let you know how long we have had ours and it still working!!

I have an invoice dated 12/20/04 for a medium sphere that was a gift to me from my husband for that christmas. There are three shrimp in it.

I have a small sphere serial #266271 and the last shrimp died in October 2011. The ecosphere was a gift and I cannot remember when it was given to me. I think that it was around 2001 or 2002. Thank you so much for a wonderful product.

I just wanted to let you know that I have had my Small Pod EcoSphere for 11 1/2 years now. I received it as a birthday present in June, 2000. It started out having 4 shrimp and I currently have 2 still living. Just amazing that it has lasted this long. I don’t even do anything with it. I’ve never cleaned it but it just keeps sustaining life. The shrimp are always interesting to watch too! Just thought I’d share with you how long mine has lasted and I still enjoy looking at it!

I have had my 5 1/4″ EcoSphere for over 11.5 years, on my desk in my office, under office lighting, and it still has 2 shrimp remaining. I have been waiting to send in for an upgrade to the large or extra large sphere for about 5 years, but these 2 just keep on going. On the back of the “Handbook” is a serial number of 175680 and the Issue Date says 6/8/00.

My ecosphere is 12 years old and still alive. It is awesome

I bought my EcoSphere at the Denver airport during a business trip many years ago… It was around 2000–2002. To be honest I am not completely sure (it was so long ago that I am still amazed). Both shrimps are still alive and doing great, but the algae is now white. It has being this way for more than 4 years.

I started practicing law in 2004 and purchased an Ecosphere as a gift to myself. Now in 2012, and I still have my shrimp prominently displayed on my desk. The two original shrimp are still very active. They have provided me a talking point, enjoyment, and pets at work. These two tough guys have even survived a few unfortunate shakes from when visitors thought they were a snow globe. I just thought I would pass on my amazement in your product. All the best.
