The animals defecate at regular intervals: once an hour in the 5-centimetre-long adults, and once every 10 minutes or so in the larvae. tentacles that are used roughly like fishing lines for capturing ctenophores tend to be much more fragile that coastal species, evidence has shown even more apparent separation. Despite long-standing experimental interest in ctenophores due to their unique biology, ecological influence and evolutionary status, previous work has largely been constrained by the periodic seasonal availability of wild-caught animals and difficulty in reliably closing the life cycle.
