What is "sharek"

Sharek or Shalek could have been a poorly known ancient Egyptian pharaoh during the Second Intermediate Period of Egypt. The Egyptologists Nicolas Grimal and William C. Hayes have proposed that Sharek should be identified with a king named Salitis, given as the founder of the Hyksos 15th Dynasty in Manetho's Aegyptiaca, a history of Egypt written in the 2nd century BC. They further propose that Sharek/Salitis is the same person as Sheshi, a ruler during Egypt's second intermediate period mentioned on nearly 400 scarab seals.
