context_page_description: Prognathodes aculeatus, the longsnout butterflyfish, is a species of butterflyfish found in tropical West Atlantic waters. It is also known as the butterbun, the Caribbean longsnout butterflyfish, or Poey's butterflyfish. This species should not be confused with the banded longsnout butterflyfish.
context_section_description: The longsnout butterflyfish was first described in 1860 by two scientists: Felipe Poey y Aloy and Albert C. L. G. Günther. Between them the fish was given three separate scientific names each one in a different genus. It was again described in 1880 by Sauvage who gave it yet another scientific name.
