Welcome to the genome browser of the marine sponge Tethya wilhelma
Tethya wilhelma (Class: Demospongiae, Family: Tethyidae) is a ball-shaped demosponge that undergoes cyclic contractions. It is an emerging laboratory model for many topics, including multicellularity, early-animal evolution, biomineralization, and microbial interactions. The original description by Sarà, Nickel & Brümmer (2001) can be found here.
