STROM

They come from constellation Ursa Minor.

Stroms are invertebrates and coelenterates. Their average height is 2 meters (6.5').

Vegetation is of great importance to their culture...and the main reason for their visits to Earth.

They have been on Earth at least 200 times.

They act with extreme caution and are rarely seen by humans.

First visited Earth at the end of the last big Ice Age. They have 20 colonies in the Via Lactea galaxy.

Their ships have the shape of an octagon.

Last sighting: October 1976 in Oregon, USA.
