''Jasus paulensis'', also commonly known as the St Paul rock lobster, is a species of spiny lobster found in the waters around Saint Paul Island in the southern Indian Ocean and around Tristan da Cunha in the southern Atlantic Ocean. At one time the rock lobsters on Tristan da Cunha were believed to be a separate species known as the Tristan rock lobster (''Jasus tristani''), but the use of mitochondrial DNA sequencing has shown them to be identical. Some authorities, for example the IUCN, retain them as separate species. The Tristan rock lobster features on the coat of arms and the flag of Tristan da Cunha. ==Description== Males of this species grow to a total length of about with a carapace length of while females may attain a total length of . Like other rock lobsters, it lacks chelae (claws) on its front pair of walking legs. The carapace is armoured with large flat spines, about as wide as they are long, mixed with small spines. The first few abdominal segments are sculptured with fine transverse grooves at the front of each segment with a smoother area behind.
