- 2003-07-01 (UPDATED 2003-07-11) Chilean Blob: Not A Cephalopod
- A 12 meter long blob was found on a beach in Chile. It was suspected of being a giant octopus. Turned out to be decayed whale blubber.
- 2003-04-01 (UPDATED 2003-05-24) Colossal Squid Caught
- Fishermen near Antarctica have caught a rare, virtually intact specimen of Mesonychoteuthis hamiltoni (or "colossal squid") -- a very large, very aggressive squid with scores of razor-sharp hooks on its tentacles. Includes article round-up, photos and email from Steve O'Shea.
