We performed a 40-day experiment on 108 individuals of M. senile collected from the Akkeshi-ko estuary in Japan to test their survivability in higher temperatures and their upper and lower salinity survivability limits. …Taxonomy: Metridium senile was first de- scribed by Linnaeus in 1761. When it was first described, scientists believed that there was only one, very diverse species of Metridium: M. senile. Hand (1955) took the first step in dividing this species by distin- guishing the Atlantic and Pacific populations as subspecies. Metridium farcimen is a carnivore. It captures small invertebrates, zooplankton and other food particles with the nematocysts on its tentacles and thrusts them into the mouth in the centre of its oral disc.
