New Recent very small but sexually mature brachiopods have been found at abyssal depths (4580-4850 m) in the Clarion-Clipperton Zone of the Pacific Ocean. They are characterized by simple (under-developed, juvenile) morphological features, which are interpreted here as paedomorphic, indicating the importance of heterochrony in the evolution of deep-sea brachiopods. We have described these brachiopods as representing two new genera and species, i.e. Oceanithyris juveniformis Bitner & Zezina (Family ?Dyscoliidae) and Simpliciforma profunda Bitner & Zezina (Superfamily Gwynioidea).
