Pyrodictium
Sign in to savePyrodictium is a genus in the family Pyrodictiaceae. It is a genus of submarine hyperthermophilic Archaea whose optimal growth temperature range is 80 to 110°C. They have a unique cell structure involving a network of cannulae and flat, disk-shaped cells. Pyrodictium are found in the porous walls of deep-sea vents where the temperatures inside get as high as 400°C, while the outside marine environment is typically 3°C. Pyrodictium is apparently able to adapt morphologically to this type of hot–cold habitat.

== Genome structure == Much research has been done on the genetics of Pyrodictium in order to understand its ability to survive and even thrive in such extreme temperatures. The thermal stability of Pyrodictum occultum's isolate tRNA has been analyzed, indicating that modifications in the nucleosides allow the organism to withstand temperatures well over 100°C.
