The blue-spotted jawfish (Opistognathus rosenblatti) is a small species of fish that lives in holes it digs in the ocean floor. It is only found in Endless Ocean 2.

This fish is named for its prominent blue spots. These spots are very bright and are scattered evenly across its yellowish scales. If disturbed, it flees quickly into its burrow.

Description

As its name suggests, this fish is covered in attractive blue spots. It digs a hole in the seabed for its nest, where males incubate the young in their mouths.

Location

Endless Ocean 2

The blue-spotted jawfish can only be found in Gatama Atoll at coordinates E-5, under a zoom-mode spot just west of the private island next to the Private Reef Entrance. It often shares its zoom-mode spot with a moorish idol.

Behavior

These fish can be found nesting in holes in the seafloor, tunneled into the sand. If poked, they quickly retreat into their burrow, but their favor can be earned with food.

Notes

• This fish is the only species of jawfish that makes an appearance in either game.

Real-Life Information

1/2

• The in-game description notes that the male blue-spotted jawfish incubates its eggs in its mouth. This much is true, and males have even specifically developed larger mouths than females for this very purpose. This type of egg care is called "mouthbrooding".
  • One study found that blue-spotted jawfish raised in captivity did not display this behavior. Aquaculturists have also noted as much in anecdotes of their own experiences with captive blue-spots.
  • Prior to breeding, male blue-spotted jawfish perform a "dance" to attract females. They swim a few feet out from their burrows, hover in place for a few seconds with their fins out, and then dart back to their homes before repeating the process until a female decides to keep them company.
    • The front half of the male fish's body turns white when he's trying to court females.
• The description also reports that the blue-spotted jawfish digs its own burrows in the seabed. This is accurate. An interesting habit that the blue-spotted jawfish has is that it will close up the entrance to its burrow every evening, and rebuild it in the morning.
• Despite being seen alone in-game, the blue-spotted jawfish readily forms colonies in the wild that can range up to hundreds of fish strong. However, it will become defensive if another jawfish tries to enter its personal nest. They also tend to be more territorial in captivity, though a very large tank can house a small colony of jawfish without them getting aggressive.
• The blue-spotted jawfish is a popular aquarium fish. However, it requires somewhat specialized care, due to the fact that it inhabits cooler water than the vast majority of other marine fishes kept in aquariums. It is also notorious for trying to jump out of its tank, as it gets startled fairly easily.
• The blue-spotted jawfish is sometimes called the blue-dot jawfish. It is less frequently referred to as Rosenblatt’s jawfish, a name that originates with the man that inspired its scientific name, Richard Rosenblatt, who was a well-known ichthyologist from the Scripps Institute of Oceanography.
