Colossal squid
The largest recorded specimen was captured in 2007 by a New Zealand fishing boat off Antarctica. It was initially estimated to measure in length and weigh . The squid was taken back to New Zealand for scientific study. A study on the specimen later showed its actual weight was , but it only measured in total length as a result of the tentacles' shrinking "post mortem".

The Darwin Centre is host to Archie, an 8.62-metre-long giant squid taken alive in a fishing net near the Falkland Islands in 2004. The squid is not on general display, but stored in the large tank room in the basement of the Phase 1 building. It is possible for members of the public to visit and view non-exhibited items behind the scenes for a fee by booking onto one of the several Spirit Collection Tours offered daily. 
On arrival at the museum, the specimen was immediately frozen while preparations commenced for its permanent storage. Since few complete and reasonably fresh examples of the species exist, "wet storage" was chosen, leaving the squid undissected. A 9.45-metre acrylic tank was constructed (by the same team that provide tanks to Damien Hirst), and the body preserved using a mixture of formalin and saline solution.
