This paper develops a cryopreservation protocol for Platynereis dumerilii larvae, achieving 34% survival after 5 months with a specific cooling and thawing regimen.

The paper describes the whole-body synaptic connectome of a segmented annelid larva, identifying segment-specific and repeated cell types and pathways.

A whole-body serial electron microscopy volume of a three-segment Platynereis dumerilii larva gives over 1,500 reconstructed neurons, 6,500 non-neuronal cells, 180 neuronal types and traced sensory-to-effector pathways.

The paper identifies polycystin-mediated mechanosensation in Platynereis larvae that triggers a coordinated startle response for predator avoidance.

The paper shows ciliary and rhabdomeric photoreceptors in Platynereis larvae functionally integrate to determine vertical swimming direction based on light ratios, acting as a depth gauge.

The paper identifies ciliomotor neurons in Platynereis larvae that coordinate ciliary activity through cholinergic, serotonergic, and catecholaminergic signaling.
