The first 24 hours in 1.5 minutes of bryozoan embryos.
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!
