PyroDinos are bioluminescent marine plankton classified as Pyrocystis fusiformis (aka Dinoflagellates).  Also incorrectly referred to as tiny shrimp lights, baby sea monkeys and The LEDs of the Sea

200ml (7oz)

PyroDinos use light to grow (like a plant) and glow blue at night when disturbed.  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!  No really - do not drink them!


After delivery:

PyroDinos will require daily lighting (low to moderate room lighting), 8- 12 hours a day.  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.    Loosen cap once a week to allow for some air-exchange.

Detailed PyroDino Instructions

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

    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.

    Brighter than any culture I've ever gotten.

    This culture was so bright the glow is even slightly visible in daylight! I've never seen a culture so dense before and will be dividing it within the coming week. Would 1000% order from PyroFarms again.

    More than expected!

    My boyfriend and I recently went on a kayaking trip to see comb jellies (bioluminescence organisms), but were super disappointed with their glow. After the trip I wanted to surprise him with some dinos. I found a few places that sold them and everywhere I read said that it would take a few days to recover from shipping for their glow to occur. The first night we got them, we were so anxious to see that we tried anyways. I literally gasped when then lit up! We were like little kids seeing a magic trick. The culture arrived healthy and lit up BRIGHT! Very very happy with my purchase and the delivery of the culture. It was a birthday gift so I would have been bummed surprising him with a dead culture. THANK YOU for showing us how awesome bioluminescence can be! We are in love <3

    Just what I needed!

    After my biopop Dino pet died, I wasn't sure how to replace it. These dinos in the food provided or so active almost right out of the box. It's brought back to life my cute little Dino light. Now I have a great place to get food for it! Quick, secure shipping. Great product!

    So cool!

    They arrived alive and are now shining on us nightly. Gotta remember to feed them and keep them alive and happy!
