Abstract

The Craspedacusta sowerbii jellyfish is an invasive freshwater species of Chinese origin, which currently has a worldwide distribution. In Chile, it was recorded for the first time in 1942 at Dam Marga Marga (32° S), subsequently expanding its distribution to reach 41° S, in the Pichilaguna Lagoon. In this report we register the presence of Craspedacusta cf. sowerbii in Chiloé Island, in Lake Natri, corresponding to the southernmost finding of this species in Chile.
