A large Humboldt squid caught on a shark-tagging expedition.

a photo by Carl Safina (the guest researcher and author who's also blogging the trip) took of one of the squids caught during a shark-tagging expedition. See the blog post. While these squid were caught for dinner, other Humboldt squid are caught for tagging.  Check out  Bill Gilly's blog  about his squid-tagging expeditions in Mexico.
