### q10 squid are the largest invertebrates > The giant squid currently holds the record as the second-largest mollusk and extant invertebrate, exceeded only by the colossal squid. Recent studies have revealed that it feeds on deep-sea fish and other squids, but its hunting methods and reproductive cycle are still unknown. While it was long believed that there were many species within the *Architeuthis* genus, [recent genetic analysis](http://www.newscientist.com/article/dn23296-worlds-giant-squid-are-one-big-happy-family.html) suggests there is only one: [*Architeuthis dux*](http://eol.org/pages/488790/overview). Claims of lengths reaching 150 to 200 feet have been reported, even by scientists, without evidence to justify such claims. [The Smithsonian's National Museum of Natural History suggests maximum lengths of nearly 60 feet.](http://invertebrates.si.edu/giant_squid/index.html) - [View Highlight](https://read.readwise.io/read/01fn495655zszxtkd76j9fhwae) - [[Five Real Sea Monsters Brought to Life by Early Naturalists by Grace Costantino#q10 squid are the largest invertebrates|View in Vault]]
