A new toy/pet/science experiment from Vat19 is like sea monkeys on steroids. Dino Pet is a plastic shell shaped like a dinosaur, but it’s actually an aquarium for plankton. The living plankton are called dinoflagellates, which is the bioluminescent species that makes some beaches glow at night.
According to FAQ on the sales page, dinoflagellates can live one to three months on sunshine alone, or several months with food. After that, you can order more. And if you decide to buy a Dino Pet, prepare yourself for questions from your children about the ethics of keeping living beings in a small aquarium, even if they are plankton. -via Laughing Squid
