As "Aquaman" conquers the hearts of millions of fantasy film lovers worldwide while it depicts a heroic story of an undersea kingdom, multiple underwater species that feature in the Hollywood flick also draw viewers' attention toward the biodiversity deep inside our gigantic oceans.

We have compiled a group of photos that reveal the mesmerizing beauty of some most amazing creatures that make a special appearance in the film. 

Green sea turtles are one of the world's largest species of turtle, weighing around 65-130 kilograms and measuring between 3.2-3.9 feet long. These cool creatures are named after a layer of green fat that lies under their shell. Scientists believe this unusual quirky-colored fat is the result of their veggie diet – unlike most other sea turtles, the green sea turtle eats marine plants such as seaweed and sea grass.

Spotted eagle rays are often observed cruising close to the surface. They are also known to "porpoise" – or leap – out of the water. As with other ray species, spotted eagle rays possess flat plates of teeth which are used to crush the hardened shells of preys items such as bivalves and crustaceans.

As the largest fish in the sea, reaching lengths of 40 feet or more, whale sharks have an enormous menu to choose from. Fortunately for most sea-dwellers—and us!—their favorite meal is plankton. They scoop these tiny plants and animals up, along with any small fish that happen to be around, with their colossal gaping mouths while swimming close to the water's surface.

The lion's mane jellyfish can grow up to over 6.5 feet wide and its tentacles can be up to 197 feet long.The lion's mane jellyfish is the largest jellyfish in the Atlantic Ocean. As with all jellyfish, the mouth of the lion's mane jellyfish is located on the underside of the bell-shaped body.The lion's mane jellyfish is often bioluminescent, emitting its own light.

The infamous great white shark has been stigmatized as a bloodthirsty killer for decades but many enthusiasts are trying to finally get rid of this misconception. As the largest predatory fish on the earth, great white sharks can grow to an average of 15 feet in length, though individuals exceeding 20 feet have been recorded. With abilities to detect one drop of blood in 100 liters, it's clear to see why film directors have used this enormous fish as a vicious predator in many Hollywood blockbusters.
