Otters belong to a comparatively small group of animals called Mustellines, shared by badger, mongoose, weasel, stoat, mink and others. They are found in large numbers in marshes. Arabs keep them as pets and tame them. Otters love to spread water and splash in it. Maxwell’s otter was of a race previously unknown to science and was at length named by zoologists Lutrogale Perspicillata Maxwelli.
