Beginning this #WormWednesday with the beginnings of a worm. The cleavage stages of the annelid Chaetopterus.
At some point in our lives, we have all been through that (=embryonic cleavage).
I’ve filmed the nemertean worm Lineus longissimus feeding on dead annelids! An example of necrophagy.
The BEST footage of bryozoan life cycle in the internet. Meet the coronate larva of Bugula neritina. Wow!
