The Tasmanian Seamounts (also Tasman Seamounts and Tasmania Seamounts) are a group of seamounts (underwater volcanoes) located off the southern tip of Tasmania. The seamounts were created more than 55 million years ago by the Tasman hotspot. The seamounts are ecologically important, and harbor a lush marine ecosystem, but are threatened by overfishing. For this reason, part of the Tasmanian Seamounts were incorporated into a marine reserve in 1999.
