How long can sea urchins live out of water?

Answer 1

What is the time limit of sea urchins out of water before they die like 2 min

Answer 2

"When kids say 'average' they are really getting themselves into trouble! Most sea urchins are mass spawners, producing several million eggs. If even a tiny percentage are fertilized, you will have thousands of live offspring. And only a small percentage of these survive in their planktonic form without starving or being eaten until they find a place to settle as tiny adult urchins. Of these, only a handful will survive to spawn (and perhaps none). If I were being mathematically and linguistically correct I would have to answer your question, "The *average* lifespan of an urchin is 10-12 days!"

On the west coast the intertidal sea urchins that kids come in contact with, like purple sea urchins (Strongylocentrotus purpuratus), are thought to be able live as long as thirty years. " - (author:Henrik Kibak)
