Smooth-coated otters (Lutrogale perspicillata) are inhabitants of the waterways of India and Singapore. Otter families typically consist of a single mating pair with mature, nonbreeding siblings living in family groups, or "romps". We note here the presence of multiple reproductive female otters within some romps, as well as the possible existence of simultaneous litters by different mothers. This phenomenon has not been recorded among L. perspicillata before. Here we address possible influences leading to multiple reproductive females within romps of smooth-coated otters, including inclusive fitness, incomplete suppression of reproduction, and existing in an urban environment. The numerous, recurring observations of multiple reproductive females warrant further investigation; while uncommon, this phenomenon is not as rare as once thought.
