He does a hell of a lot more than just talk to fish and swim, okay.
Okay everybody take your seats, it's time to learn a thing or two...
Aquaman's body is specially developed for underwater conditions, granting him specialized blood circulation to withstand freezing temperatures and highly developed vision to see clearly even in murky ocean depths. This hybrid physiology means he can survive indefinitely underwater or on land (though he would still need occasional contact with water to survive)this length can be prolonged by the humidity in the air.
He also possesses superhuman levels of strength, speed, endurance and durability, all by-products of his body being adapted to survive unprotected in the tremendous pressures of the ocean depths.
Although other Atlanteans possess similar adaptations, Aquaman is super-Atlantean as well as super-human, and as such he has greater physical capabilities than does a typical Atlantean.
Superhuman Strength
'Superhuman Speed': said to be the fastest thing underwater, he can swim fast enough to beat a fighter jet at top speed flying overhead. He has been clocked at 1 thousand knots.
Superhuman Endurance
Superhuman Durability
Marine Telepathy: Aquaman has a form of telepathy which works particularly well on other aquatic life. This is related to the universal force known as the Clear.
Echo Location: Aquaman has highly enhanced senses, most notably a natural form of sonar.
Energy-Heat Resistance: Aquaman is extremely resistant to energy/heat based attacks as he has with stood multiple blasts from Amazo's heat vision, Black Mantas heat beams, and energy blasts from an Omac.
Aquaman lost his hand once upon a time and was given a magical hand by the Lady of the Lake. It's called the Waterbearer Hand, here's what it can do:
Molecular Manipulation: Aquaman can alter the shape and density of the hand.
Healing: It possesses healing properties.
Farsight: Can be used as a scrying pool.
Negate Magic: Can negate other magics.
Prolong Adaptation: Significantly increases the time Aquaman can spend out of water.
Independent Life: The hand can be separated from Aquaman and continue to work.
Strength Level: Aquaman has proven capable of lifting an oil platform and a chunk of a city block, both weighing in at the hundreds ( and potentially hundreds of thousands) of tons marks.
