In a significant move, the United States Navy has confirmed the identity of a sunken World War II aircraft carrier in the Sulu Sea as the USS Ommaney Bay.

The carrier, which met its demise in 1945, was sunk by a devastating kamikaze attack during the ferocious battles of the Pacific Theater. Through meticulous examination and research, the navy has now shed light on the final resting place of this legendary warship.

In a bid to learn more about ghost sharks, researchers from the University of Florida (UF) and the Seattle Aquarium are using remotely operated vehicles (ROVs) to explore the oceanic depths 100 meters below the surface of the Pacific Northwest.

In particular, they want to find the nesting grounds of the Pacific spotted ratfish, as currently very little is known about their spawning habits and embryonic development.

Scientists have observed neon tetra fish queuing up when exiting through a narrow opening, according to a study in the journal Scientific Reports.

In the study, Aurélie Dupont, a biological physicist in the Laboratoire Interdisciplinaire de Physique at University Grenoble Alpes, and her team set up two fish tanks connected to each other by a narrow opening. The diameter of the passageway varied from 1.5 to 4 centimeters.

According to satellite data, 56 percent of the world's oceans have experienced a colour change from blue to green over the past 20 years. The changes are especially noticeable in tropical areas close to the Equator.

According to researchers, the gradual greening of our oceans indicates how climate change is affecting aquatic life.
