Resumo

It is known that the type of development of marine invertebrates is related to the size of the eggs. Data on the maximum size of oocytes of deep-sea acorn worms of the Torquaratoridae family are presented. It has been suggested that among the Torquaratoridae there are species with direct development, species with lecithotrophic larvae and species with planktotrophic larvae. Mysterious giant larvae of Planctosphaera pelagica may be planktotrophic larvae of Torquaratoridae.
