DIY Miniature Ocean in a Jar: How To Make a Living-Sea Ecosphere

If you are fascinated by life and living things, big and small, and do not live on a farm, you might probably be an ant farm type of person. If you are however over that pet project idea, or not quite ready for the responsibility to look at and after a huge sandcastle in a glass enclosure in your room, with your thousands of miniature pets, then there is a project you can perhaps try out in more of a less-invading microcosmos.

Life in an airtight sealed jar does not sound like a feasible or viable project. You will, however, be surprised to find that, filled with water and only sunlight as an energy source, insects and organisms, which are large enough to be observed with the naked eye, can not only just live, but sometimes flourish in this condition.

A seacosphere, which is a jar filled with seawater, sea sand, some miniature sea life, most of which is coming complimentary with the sand and sea plants, can sustain itself for longer than a year. The larger sea creatures like sea star’s and crab’s lifespan are limited more in this ecosphere than the microorganisms like crustaceans, paramecium, worms, and invertebrates, as they require more resources.

Except for the joy in monitoring the fascinating isolated life cycle you created in your microcosmos in a jar, you can also make a study of the actual names of the inhabitants, what they are and how they function. You will experience the cycle of life and death of creatures and organisms in this miniature world and will most probably be astounded at the resilience of life when you think there should be none.

Start your new pet hobby with step-by-step instructions to create your own seacosphere and see how much there is to learn from life in a water-filled jar.

Let’s take a deeper look into the incredible world of ecospheres and explore more sophisticated closed-system ecospheres. Enjoy watching.
