Abstract

The type of development is known to correlate with the egg size in marine invertebrates. Data on the maximum oocyte size were considered for deep-sea acorn worms of the family Torquaratoridae. The family was assumed to include 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.

摘要

已知发育类型与海洋无脊椎动物的卵大小相关。我们考虑了Torquaratoridae科深海橡实虫的最大卵母细胞大小数据。该科被认为包括直接发育的物种、卵黄营养型幼虫的物种和浮游营养型幼虫的物种。浮游球虫神秘的巨型幼虫可能是Torquaratoridae科的浮游营养型幼虫。
