The large lecithotrophic eggs of the bathyal echinothuriid sea urchin
Araeosoma fenestratum are positively buoyant both in vitro and in situ. In the
laboratory, some eggs of A. fenestratum were negatively or neutrally buoyant at 10⁰C,
but all eggs were positively buoyant at higher te mperatures (> 15⁰C). In situ, all eggs
were positively buoyant from the surface to 790 m depth, spaning temperatures of 9⁰ to
27⁰C. At constant salinity, flotation rate is directly related to temperature; eggs
ascend more slowly at colder temperatures. We predict that eggs of A. fenestratum could reach the surface from a depth of 800m in 4.2 days. Florida Atlantic University.
