Fun Facts About Barreleye Fish – About Barreleye Fish
The Barreleye fish, also known as Macropinna microstoma, is a deep-sea fish that is primarily found in the Pacific Ocean, particularly in the waters off the coast of California. It is a small fish, typically measuring no more than six inches in length, and it is characterized by its distinctive transparent head.
The Barreleye fish has large, upward-facing eyes that can rotate within its transparent, fluid-filled head. This allows the fish to look directly upwards and track the silhouettes of prey, such as jellyfish and other small animals, that may be swimming above it. The fish also has a long, thin snout that it uses to catch its prey.
The Barreleye fish was first discovered in 1939, but it was not until the 2000s that scientists were able to observe the fish in its natural habitat using remotely operated underwater vehicles (ROVs). These observations provided new insights into the behavior and ecology of this unique and fascinating fish.

Fun Facts About Barreleye Fish – Where Barreleye Fish Live
In addition to to the fun facts about Barreleye Fish, here is a little information on where Barreleye Fish live.
Barreleye Fish (Macropinna microstoma) are found in the deep-sea waters of the Pacific Ocean, particularly in the North Pacific.
They are typically found at depths of between 600 to 800 meters (2,000 to 2,600 feet), but they have been known to live as deep as 2,500 meters (8,200 feet).
