The barreleye is a sea fish in the Animal Crossing series, introduced in Animal Crossing: New Horizons. Selling for  15,000 Bells, it is tied with the coelacanth and great white shark as the most valuable saltwater fish in the Animal Crossing series. The barreleye is one of two fish introduced in New Horizons that can only be caught from 9 PM to 4 AM, the other being the snapping turtle. Additionally, it and the snapping turtle are two of the only four fish in the game to be caught exclusively during that time frame, with the others being the saddled bichir and blowfish returning from Animal Crossing: New Leaf. Of those four, it is the only one to be available year-round as a small shadow.

It also appears in Animal Crossing: Pocket Camp as an event fish that was available for a limited time during Fishing Tourney: Fintastic, from November 12 to November 19, 2020.

Donating to the museum[edit]

Like all fish, bugs, and sea creatures in the Animal Crossing series, the barreleye can be donated to the museum by talking to Blathers, the curator. He will tell the player some information about it when the player donates it.

In New Horizons[edit]

When donating to Blathers or selecting "Tell me about this!" in New Horizons, he will provide the following information about the fish:

"The barreleye is a deep-sea fish with protuberant eyes and a clear head, so some of its organs are... visible. At first blush, a transparent head seems absurd, but there is a reason: so it can see things directly above! But I must confess - the more I learn about deep-sea fish, the happier I am to live on dry land, wot."

When donated, the barreleye can be found in the north-eastern-most room of the fish exhibit, in the "sea" tank which is near the submersible and diving suit. It shares this tank with the coelacanth, football fish, and oarfish.


Real-world information[edit]

Macropinna microstoma is the only species of fish in the genus Macropinna, belonging to the Opisthoproctidae, the barreleye family. It is recognized for a highly unusual transparent, fluid-filled dome on its head, through which the lenses of its eyes can be seen. The eyes have a barrel shape and can be rotated to point either forward or straight up, looking through the fish's transparent dome. M. microstoma has a tiny mouth and most of its body is covered with large scales. The fish normally hangs nearly motionless in the water, at a depth of about 600 metres (2,000 ft) to 800 metres (2,600 ft), using its large fins for stability and with its eyes directed upward.

M. microstoma has been known to science since 1939, but is not known to have been photographed alive until 2004. Old drawings do not show the transparent dome, as it is usually destroyed when brought up from the depths.
