Giant Pacific Octopus!

The largest octopus is the Pacific Giant Octopus, Enteroctopus dofleini.  According to data from a 1987 Masters Thesis from J.A. Cosgrove, the Pacific Giant Ocotopus can reach a weight of over 150 pounds (>70kg).  Our friend Jason Bradley, underwater photographer extraordinaire and honorary DSN photographer (post, post, post, post) captured this amazing shot at God’s Pocket in British Columbia.  He estimates is only to be just over 30 pounds.

  1. Wow what a cool site! Found it through a Reddit link. Is there anyway for people to help support like a hoodie with the deep sea logo to purchase or a paypal to donate, such a cool mission I just wish I could help.

  2. This fellow looks very similar to the ones we get down here, and they can do an 8 srm crawl across a wet deck and slide overboard thru a scupper at an unbelievable speed.the largest I have seen here would be about five feet across spread out.
