Triassic Triops Cooler Than Monkeys. Triops: way cooler, bigger and more active than sea monkeys. They&#39;re dinosaur shrimp, leftovers from some 200 million years ago. Don&#39;t eat them; just grow them and enjoy this bizarre &#38; ancient display of nature! You get a kidney-shaped tank 2-3/8" tall x 8-1/2"x 5-3/4", a very informative instruction booklet, and a packet full of triops eggs and food. Add the eggs to water and watch them go; they&#39;ll hatch in a day and reach 1" to 2" or more in a few weeks. Really easy to do, and really cool too.
