PyroDinos -3 pack- (600ml)

Regular price $87.00 $69.00 Sale

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

3 x 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:

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.

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 60 days after arrival. 


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

    Highly Not Recommended

    Arrived dead, were unable to provide a second culture and simply refunded me. Do not buy unless you live in a major high population city with access to a vast network of shipping facilities that could get your dinopyro's from their staging location in California to your door step in a matter of days. For most people there is no point and just leads to frustration and disappointment :c


    Sorry about the inconvenience. We refunded the order. FedEx does not ship to PO Boxes. So we have no way to ship internationally to a PO Box in an effective manner.

    Second round glows bright

    Great! Unfortunately, the first batch of PyroDinos shipped here during a brutal cold spell earlier this year. They didn’t survive. Your customer service representative quickly sent me a code for a free second order and they arrived a few weeks ago. The dinos are healthy and they glow brightly every night. Also, our cats are very intrigued by the seawater smell. Great purchase, so unique. I love them. Thank you.

    I love my dinos!

    Dinos arrived happy, glowy, and healthy! I've had them for two weeks, and they are still happy and glowy and healthy at night. I am loving my happy little glowy buddies!

    They arrived as advertised and all’s well

    After sending an email asking the volume of the Pyro Dinos (not on packaging) so I could calculate how many milliliters to feed weekly, no issues. Need to get some for my granddaughter….
