'Extinct' giant sponges, once used as bath tubs, are rediscovered

It's the sponge that takes the idea of a sponge bath to a whole new level: the giant Neptune's Cup. First discovered in 1822, these sponges once grew so large that they were commonly used as bath tubs for children. However, that handy use quickly led to overharvesting, and the last time anyone saw one alive was in 1908. Many believed the sponges had become extinct.

That was until March of this year, when biologists doing a routine survey dive along Singapore's coast spotted something that none of them could immediately identify. Of course they couldn't: a living Neptune's Cup sponge hadn't been spied for more than 100 years. more
