The Yellow Longnose Butterflyfish, also known as the Longnose Butterflyfish (Forcipiger flavissimus), is a species of coral-reef fish found in both Endless Ocean and Endless Ocean: Blue World.

It is very common and easy to identify. Its name comes from its most distinctive feature: a long snout that it uses to search for tiny crustaceans to eat.

Encyclopedia Description

Endless Ocean

"These fish have narrow, elliptical bodies with extremely long mouths. Though mostly yellow, they sport a thick black band around the head and mouth. They can be seen year-round all over Manoa Lai.

These fish live near rocky or coral reefs and use their long, narrow snouts to access small gaps in the coral. They feed on any unfortunate creatures that happen to be there.

They swim in schools near the ocean floor and can often be seen resting in holes and gaps between rocks. While resting, they will often turn upside down so their bellies face the surface."

Endless Ocean: Blue World

"This yellow fish uses its distinctive elongated snout to get into openings in coral and eat small animals hidden inside. It sometimes rests in caves and crevices, and when in a cave it floats upside down with its belly pointing upwards."


Endless Ocean

These can be found all over the Manoa Lai Sea, as well as under zoom-mode glows in the Great Aqua Cave.

Endless Ocean: Blue World

These are found in Zahhab Region.


These swim as small, loose groups over coral. These can also be found under glows, alone or with other fish.


Real-Life Information

  • This fish is also sometimes called the forceps fish, owing to the characteristic long nose that acts like a pair of forceps - an elongated instrument used in medical procedures for picking up and/or holding things[1][2].
    • This function of the snout is mentioned in both-in game descriptions, specifically in reference to the fact that they sometimes use their long snouts to investigate niches in the coral where prey might be hiding (which is accurate to real-life behavior)[3].
  • Both games make note of the fact that the yellow longnose butterflyfish tends to go upside-down whenever it is resting in a crack or crevice in the rocks it lives in. This much is accurate, but it will also display this behavior near steep slopes or ledges[2][4][5][6].
  • Something interesting about the yellow longnose butterflyfish and the other species in its genus is that they can all make sound in order to ward off other butterflyfish from entering their territory[7]. Larger and stronger butterflyfish can use their larger musculature to create louder and longer sounds, which signals their strength to other butterflyfish[8].
  • In the genus Forcipiger, there are three species[9]. Forcipiger longirostris, the big longnose butterflyfish, is similar to F. flavissimus (the species seen in-game), but with a longer snout[10]. The third species is Forcipiger wanai, which was named in 2012 and is called the Cenderawasih longnose butterflyfish[11]; it has only been found in Indonesia so far, and has a darker body than its relatives[12].
    • The other two species do not appear in either game in the Endless Ocean series.
  • This fish is often found in aquariums, both public and private[13]. It adapts easily to captivity, though is best reserved for slightly more experienced aquarists, and get along well with other peaceful fish[14]. They will occasionally pick at corals or clams, but generally prefer eating small worms and other such invertebrates instead[15].
    • In the wild, they are also known to bite off small pieces of larger prey, such as the feet off of sea urchins or the tentacles off of tube worms[16][17].
