they were probably made by storms
None. Saturn has a great white spot, Uranus has a dark spot. However, Neptune has a great dark spot [see related link for a picture] which has been compared to Jupiters great red spot, but it is not red.
The Great Dark Spot on Neptune is a massive storm system, similar to Jupiter's Great Red Spot, that was observed in the atmosphere of Neptune. It is an atmospheric feature characterized by its dark appearance and is thought to be a large cyclonic storm. The Great Dark Spot was first observed by the Voyager 2 spacecraft in 1989.
It is the Great Red Spot. The Great Dark Spot was a storm on Neptune while Pluto has an elgonated orbit.

The Great Red Spot is a massive storm on Jupiter that has been raging for hundreds of years. It is a high-pressure system that is larger than Earth. The Great Dark Spot was a storm on Neptune that was observed in 1989 by the Voyager 2 spacecraft. It was a large, dark storm system that eventually dissipated.
Neptune's atmosphere has zones like Jupiter, and the dark spot aka the "Great Dark Spot" is about the size of the Earth. It's caused by a storm much like Jupiter's Great Red Spot only much smaller. The lighter colored clouds of methane crystals in the upper atmosphere is simply being blown away by this storm to reveal the darker layer of gases underneath.
No, it is a storm, similar to the Great Red Spot on Jupiter.
The Great Red Spot is an anticyclonic storm raging on the surface of Jupiter. It has been raging for hundreds of years. The Great Dark Spot was a similar storm on Neptune. However is has now disappeared and smaller spots are regularly sighted in the atmosphere.
Neptune. It's Great dark spot resembles that of Jupiter's Great Red Spot.
No. Neptune is a gas giant, it has no solid surface. Therefore no volcanoes can form on the planet. The Great Dark Spot is an anticyclonic storm, just like the Great Red Spot on Jupiter. Unlike Jupiter's Great Red Spot which has lasted for hundreds (possibly thousands) of years, the Great Dark Spots of Neptune last only a handful of years before vanishing. See the related link below.
The planet Neptune had a great dark spot. It soon vanished after discovery, leading astronomers to believe it was just a temporary storm, unlike the Great Red Spot on Jupiter which has been raging for hundreds of years. See the related link for more information.
Neptune has a massive anti-cyclonic storm system spanning 13,000 x 6,600 km It is called "The Great Dark Spot". There is also a smaller cyclonic storm in the southern region, called, not surprisingly, "The Small Dark Spot"
