Umbonia Spinosa

If you like picking up twigs or thorns out in the wild one day, you might end up disturbing this chap. The Umbonia Spinosa belongs to the Membracidae species found in South America, also referred to as treehoppers. However, there are an estimated 3,200 treehopper species distributed in all continents except for Antarctica.

Their dorsal fin is the most prominent feature they possess, which also earned them the nickname thorn bug. When it’s raining, several of these insects, collect together, and they might make an ordinary bush seem like it’s suddenly thorny. They have a relatively short lifespan living for just a couple of months.

Blue Dragon (Glaucus Atlanticus)

The blue dragon is a small sea slug species that belongs to the Glaucidae family. They are also known as blue sea slugs, blue angel, blue glaucus, or blue ocean slugs. The pelagic slugs are known to float upside down, working with the water’s surface tension to stay up. 

Their stomach also stores an air bubble, which helps it stay afloat. The slug is quite small, measuring just about 3 centimeters in length. They primarily feed on the marine hydrozoan, the Portuguese man o’ war as well as other pelagic creatures. They also steal appendages from the man-of-wars’ adding them to their own as a protection mechanism to scare off predators.
