There's a tiny creature that looks like Gandalf’s hat

Thecamoebians are among the 30 to 45 lineages of amoebae known to exist worldwide. During their evolution, they have developed the ability to produce a varyingly-shaped protective outer carapace or shell.

Researchers and environmental consultants in Brazil have identified a species of thecamoeba with a carapace that resembles the wizard’s hat worn by Gandalf the wizard, a key character in J.R.R. Tolkien’s The Lord Of The Rings.
