The colossal squid (Mesonychoteuthis hamiltoni), also sometimes called the Antarctic squid or giant cranch squid, is the largest squid in the world in terms of mass. Only beaten out in terms of length by the giant squid. The largest specimens (only known from beaks recovered from Sperm whale stomachs) may perhaps weigh 600-700 kilograms (1,300-1,500 lbs) - making it the largest known invertebrate.

Jurassic Park: Builder

The Colossal Squid only appears in Jurassic Park: Builder, in the Aquatic Park. It is a limited edition animal, only available for a short time period.


  • The Colossal Squid isn't extinct. Therefore it is a plothole that the creature has to be cloned from DNA in Ice in Jurassic Park: Builder. However it may have been an extinct species.
  • The Colossal Squid along with the Horseshoe crab, Coelacanth, and Nautilus, and is the only non-extinct Jurassic Park attractions in the franchise to appear so far.
  • The Colossal Squid in Jurassic Park: Builder should have a wider mantle, but the game seemed to make it resemble the Giant Squid instead.
