The group goes aboard a tramp steamer, the Rita, which is captained by crusty old Lucas Nestor Paiva. The expedition consists of David, Carl, and Mark, as well as Reeds girlfriend and colleague, Kay Lawrence Julie Adams, and another scientist, Dr. Edwin Thompson Whit Bissell. When they arrive at the camp, they discover that Maias entire research team has been mysteriously killed while he was away. Lucas suggests it was done by a jaguar, but the others are unsure. In fact, the camp was attacked by a piscine amphibious humanoid, a living member of the same species from which the fossil originated. The creature, curious upon seeing the expedition, investigates the camp site. When its sudden appearance frightens the members, they attack it, and in response the enraged creature kills them.The excavation of the area where Carl found the hand turns up nothing. Mark is ready to give up the search, but David suggests that perhaps thousands of years ago the part of the embankment containing the rest of the skeleton fell into the water and was washed downriver, broken up by the current. Lucas says that the tributary empties into a lagoon. Lucas calls it the Black Lagoon, a paradise from which no one has ever returned. The scientists decide to risk it, unaware that the amphibious Gillman that killed Carls assistants earlier has been watching them. Taking notice of the beautiful Kay, it follows the Rita all the way downriver to the Black Lagoon. Once the expedition arrives, David and Mark go diving to collect fossils from the lagoon floor. After they return, Kay goes swimming and is stalked underwater by the creature, who then gets briefly caught in one of the ships drag lines. Although it escapes, it leaves behind a claw in the net, revealing its existence to the scientists. ........
