It is now believed that S. lessoniana is a cryptic species complex. Researchers Michael Vecchione and Richard Young were the chief investigators of the finds, and eventually linked them to the two previous specimens, erecting the family Magnapinnidae in 1998, with Magnapinna pacifica as the type species. The smaller males (termed "female mimics" or "sneaker males") might have assumed body patterning typical of females in order to trick larger males. Magnapinna, or bigfin squid, is the size of a hotdog bun, but with filaments up to 7 metres long. High temperatures may induce shorter lifespans and smaller body sizes, while cooler temperatures favour longer lifespans and larger individuals.
