Crinoid Shrimp (Periclimenes sp.)
As their name suggests, crinoid shrimp are found on the feathery arms of crinoid feather stars. Amazingly, the patterns and colours of the shrimp always resemble that of their host.

Actias luna of Saturniidae
Hexagon shaped storm located over the north pole of Saturn. This unique phenomena has been active for decades (and to the best of our knowledge even centuries!) It streches 25,000km and has winds reaching 322km.
The hexagon contains various storms of different size with a vortex located directly over the plantets pole. Because saturn is a gas giant it has no landforms disrupting its winds, like with storms on earth which enable them to whirl around the planet uninterrupted for long periods of time.
