The Inexplicable Shrimpgoby (Cryptocentrus inexplicatus) was named as such by the American ichthyologist (fish studier) and lichenologist (lichen studier) Albert William Christian Theodore Herre c. 1934.
It’s not immediately obvious why the Inexplicable Shrimpgoby is (or was) inexplicable, In other words, at first glance at least, its inexplicableness appears to be unexplained.
