What is p johnsoni?

P Johnsoni is the scientific name for the Johnson's Sea Snake, one of the most venomous sea snakes in the world. It is found in the waters of the Pacific Ocean, from the coasts of Australia to Southeast Asia. It is named after the British herpetologist Harold Trapido Johnson, who first discovered this species in the 1920s.

The Johnson's Sea Snake can grow up to 1.5 meters in length and is distinguished from other sea snakes by its paddle-like tail. It has a highly toxic venom that is capable of killing a human within hours if left untreated. However, it is not aggressive and rarely bites humans, as it spends most of its time in deep waters.

This species has a unique reproductive strategy called "interior fertilization," where the male injects his sperm into the female's oviduct during copulation. The female then retains the sperm until she is ready to lay her eggs, which she does in a sheltered area near the coastline.

Due to habitat loss and overfishing, the population of the Johnson's Sea Snake is declining, and it is listed as "vulnerable" on the International Union for Conservation of Nature (IUCN) Red List. Conservation efforts, such as habitat protection and reducing by-catch in fisheries, are needed to ensure the survival of this species.
