We're big fans of the Dino Spheres and Pets here at ScienceAlert – and how can you not be?

With just sunlight, water, and nutrients to help it thrive and grow, Dino Pets are a tiny glowing pet that you get to take care of and observe at the same time.

With a swirl Dino Pets light up with bioluminescent dinoflagellates at night, giving off a beautiful blue glow.

Dinoflagellates, also known as sea sparkles, are a type of plankton - and although they can signal ecological problems under certain conditions, they're also incredible to look at.

The glow is caused by a type of cytoplasmic body called scintillons, which contain an enzyme that creates the blue colour.

In the Australian island of Tasmania, the blue bioluminescence caused by these sea sparkles has become a bit of an attraction, with people coming to take photos of it when they bloom.

Dino Pets has packaged this all up into a mesmerising shape, so you can enjoy the beauty in your own home.

The creators say the dinoflagellates and light show will last for several months before dimming, but you can buy extra nutrients to extend the lifespan.
