So the last Triops died the other day. It was a good run for them and fun for the kids to watch something grow. No eggs were laid this time, perhaps because there was no sand to lay them in? I still have more sand from the batch last year. Maybe I'll grow them again next year. It was a fun experiment for summer vacation. They may not live very long, and they are very sensitive to environmental changes and pollution, but as a species they are quite successful. Long live the Triops!
