13 Animals With Long Names (With Pictures)

Animals come in all shapes and sizes and with a variety of names. Some names may sound bizarre but are descriptive of their habits, environment, or appearance. For example, the fried egg jellyfish gets its name not because they’re made of eggs but because of their egg-like appearance.

There are also animals with long names that may be difficult to pronounce. While you may know of some dinosaurs or extinct species with long names, here’s a compilation of animals alive today with long scientific or common names.

Let’s find out if you can guess which animal has the longest name and whether they hold a record!
