Werner de Gier, a biology student at Leiden University, and shrimp expert Charles Fransen were faced with the prospect of naming a newly discovered shrimp with hairy legs. They did what any self-respecting scientists would do and named it after Bilbo Baggins, the hairy-footed hobbit from The Hobbit and the Lord of the Rings series. 

Researchers found the shrimp, now named Odontonia bagginsi, during a 2009 expedition to islands in East Indonesia. The minuscule shrimp measures a fraction of an inch (under a centimeter). It was one of two new shrimp species discovered during the trip.
