PyroDinos with DinoNutrients (300ml)

Regular price $48.00 $39.00 Sale

PyroDinos are bioluminescent marine plankton classified as Pyrocystis fusiformis (aka Dinoflagellates).  PyroDinos use light to grow (like a plant) and glow blue at night when disturbed.  They grow and perform their best when DinoNutrients are periodically added.  

The natural light produced by these plankton is called Bioluminescence.  PyroDinos will only light up at night, in the dark when gently swirled or shaken.  Enjoy them in the spout pouch or your favorite bottle or clear container.  

Do not drink PyroDinos!  They are non-toxic but live in seawater which is not digestable.    

Whats Included

200ml (7oz) PyroDino Spout Pouch

300ml (10oz) DinoNutrient Spout Pouch

Basic Instructions


After delivery:

It is OK to leave the PyroDinos in their white Spout Pouch for 1 month after delivery.  Our PyroDinos have enough resources in the pouch to sustain them for 4 weeks.  PyroDinos will require daily lighting (low to moderate room lighting), 8- 12 hours a day.  Loosen cap once a week to allow for some air-exchange.

Find a clean, clear container to pour your PyroDinos into that will allow them to grow.  Every one or two weeks, add small amounts of DinoNutrients (10 to 20%) of total volume.

Detailed PyroDino Instructions

PyroDinos will not survive more than 4 or 5 days without daily light.   


We have been growing and selling dinoflagellates since 2011 and guarantee all our dinoflagellates for 30 days after arrival. 


It is recommended to open the shipping box within 24 hours of arrival.  These little plankton need light!

    Sparkled from the very first night

    Great. The online instructions are clear, and the plankton sparkled and glowed from the very first night.

    Amazing low maintenance pets!

    Love these glowing little things. When I first got my order mine were dead as they didn�t glow. I reached out via email and they were happy to replace them. My new ones glow very bright at night! Very cool to have around the home. Thank you.

    Happy Customer!

    My 6th-grade daughter picked a really neat science project-- Bioluminescence: Investigating Glow-in-the-Dark Dinoflagellates. We ordered from a company that was listed in the middle school students' resource guide, Carolina Biological Supply. The three specimens arrived with VERY little activity even after allowing the three separate specimens to "recover" their bioluminescence after shipping. After two weeks elapsed, we observed a few sparse glowing flickers, and we started to worry that the science fair project would be a bust. Luckily, my 3td grader found an ad for PyroDinos, and their specimen literally saved the day. I am a native New Yorker and a natural skeptic. So, I was thrilled to see that PyroDino's live specimens actually glow as advertised. You do not have to squint to see the glow. The glow is bright, obvious, and intense.
