Platynereis or Spotify?

Every time I open Spotify, I see the pattern of engrailed expression in an early Platynereis larva. Once you see it, there is no turning back!

Platynereis or Spotify?
The similarity between engrailed expression in Platynereis and the Spotify logo. A) Whole-mount in situ hybridization of engrailed in a 48h larva of the annelid Platynereis dumerilii (Prud’homme et al. 2003). B) Illustration of engrailed expression pattern in Platynereis. C) Spotify logo. D) Illustration of adapted Spotify logo.

Necrophagy in the world’s longest worm

I’ve filmed the nemertean worm Lineus longissimus feeding on dead annelids! An example of necrophagy.
