Many tadpole species aggregate in nature and if larval densities are not too high there is generally a positive effect of grouping on growth and development. The benefits of grouping may be due to social facilitation and the availability of other tadpoles' faeces for consumption. We determined the effect of raising striped marsh frog (Limnodynastes peronii) tadpoles in isolation by comparing larval growth, size at metamorphosis and jumping distance at metamorphosis between full siblings raised in isolation, at low density and at high density. As expected, tadpoles raised in isolation experienced slower growth and development, which resulted in a prolonged larval duration and reduced mass and jump distance at metamorphosis. These results suggest that conspecific interactions are important for healthy growth and development of striped marsh frog larvae.
