A naval biologist named F.G Wood came to the conclusion that these hooks, which look more like teeth to me, could have only come from a squid.
This strange incident always has two suspects. The giant squid and colossal squid. I know that the giant squid does not have such structures and only being an amateur cephalopod fan and not a biologist of any kind, I’ve never seen Colossal squid hooks in person, however from what I can tell, these things don’t appear to be them. Clear pictures of hooks belonging to less famous species are harder to come across on the internet so I’ve found it hard to make a comparison.
