One of the most attractive Nudibranchs of Lembeh Strait is without a doubt the Red-Lined Jorunna (Jorunna rubescens). It’s key features are its enormous size of up to 20cm and the head, that reminds of a Puppy – that’s why it’s also sometimes called the Puppy Nudibranch. Well and yesterday we found a Puppy of the Puppy Nudibranch: A tiny 2 cm long Baby Jorunna rubescens. It is much redder than the adult and does not yet have the dark spot on the nose that will give him the dog like appearance.
