creature from the black lagoon

The Gill-man is fully amphibious, capable of breathing both in and out of the water. It possesses large, webbed hands with sharp claws on the tip of each finger. The Gill-man's scaly skin is extremely tough, which combined with a fast-acting healing factor, allows it to survive wounds which would be fatal to humans, such as gunshots and full immolation. It also possesses superhuman strength, which is flamboyantly displayed in the second and third films.

As shown in the third film, the Gill-man has a dormant set of lungs, should its gills be irreparably damaged. As shown in the first film, it is vulnerable to rotenone. The Gill-man is slightly photophobic, due to its murky water habitat. 35% of the Gill-man's blood is composed of white corpuscles, lacking a nucleus.

The last known surviving member of a race of amphibious humanoids which flourished during the Devonian age, the Gill-man (as christened by Dr. Thompson) dwelled in a lagoon located in a largely unexplored area of the Amazon rainforest. The creature was apparently known to the natives, as the captain of the boat Rita mentioned local legends of a "man-fish".After having found the fossilized remains of another Gill-man, a marine biology institute funds an expedition to the Amazon in order to find more remains. Though the Gill-man reacts violently to the intrusion, he develops a soft spot for the team's only female member and repeatedly tries to abduct her, going as far as building a makeshift dam to prevent their boat from escaping. After having killed numerous members of the expedition, the Gill-man takes her to his underwater lair, where he is tracked down by the remaining survivors

the creature's coloration is moss green, to better camouflage itself with the similarly colored waters of his lagoon. Much like many species of fish, he has pronounced lips and scales all over his body, as well as gills located on the sides of his head which is directly connected to his neck. Publicity photos and some restorations have colored the creature's lips greenHe is substantially taller than the average human male, and although never accurately measured, it is stated to be around 7 to 8 feet tall (half a centimeter more than that of the average male adult, according to Dr. Borg and the Ocean Harbor Oceanarium's measurements) and weighing approximately 300 pounds.

The Creature Walks Among Us, though feels sad in that it is in an enclosed space and wishes to return to the water, unaware that it has already adapted to land and that staying underwater for too long would mean certain death, and shows great anger when blamed for a murder he didn't commit, lashing out against the man who was going to pin an accidental death during a scuffle on the creature. Throughout all movies, despite lacking a range of emotions, Gill-man shows sadness and it's implied that he is aware that he's the last of his kind.
