FIGURE 8. Light experiments in Convolutriloba macropyga sp. nov. and the Convolutriloba genus. A. Progeny release rates of Convolutriloba macropyga sp. nov. in response to light intensity. The experiment involved 24 adult specimens each in one of three light treatments: dark, low light, and high light. Trials ran for 15 days. Results are presented as average number of asexual progeny released per individual per day. Error bars are 95% confidence intervals. B. Comparison of dark-survival of species within the genus. Twenty-four adult animals of each species (C. retrogemma, C. longifissura, C. hastifera, and C. macropyga) were subjected to total darkness to determine and compare the extent of the obligate nature of algal symbiosis between the different host species. Artemia sp. prey was provided daily in superabundance to minimize the variable of holozoic starvation. Results are presented as percent survival over time.
