Seals are capable of diving to impressive depths, with different species having varying limits. For instance, the Weddell seal can dive to depths of over 2,000 meters (around 6,600 feet), while the elephant seal can reach depths of around 1,500 meters (approximately 4,900 feet). These remarkable adaptations allow them to hunt for fish and other prey in the deep ocean. However, most seals typically dive to shallower depths, often between 200 to 500 meters.

The Red Sea is referred to as a "proto-ocean" because it is a rift basin that is in the early stages of ocean formation. It is located between the African and Arabian tectonic plates, which are slowly moving apart, leading to the development of new oceanic crust. This geological process is similar to what eventually formed larger oceans, making the Red Sea a key area for studying the early stages of oceanic development. Its unique geological features and ongoing tectonic activity provide insights into the evolution of ocean basins.

The phenomenon of seawater turning red in the end times is often referenced in religious texts, such as the Bible, specifically in the Book of Revelation, where it symbolizes divine judgment and catastrophic events.
