I use photo reference of nudibranchs and take together aspects of a few different types of the same species and then make it work for my 3D model. There are plenty photo reference done by amazing photographers out there. I have taken a few of my own photos of the nudibranchs I met while snorkelling and scuba diving. This inspired me to start this project. They are desk toys or sculptures of about 6cm long on average. I put them on top of my computer monitor using Blu-Tack/Prestik! You can also display them on aquarium man made corals and rocks. Here are photos of my products available for sale on Shapeways and Etsy:
