What type of evidence primarily supports the 1932 Bathysphaera sighting versus the 75kg specimen report?

Answer

Visual sighting vs. trapping event testimony

The text highlights a critical difference in the evidentiary basis for the two main claims regarding giant dragonfish. The account concerning *Bathysphaera intacta* is exclusively a visual sighting, reported from inside a bathysphere at an extreme depth, offering no physical proof. Conversely, the report concerning the 75-kilogram specimen is linked specifically to a documented trapping event where geoduck was used as bait, implying a capture rather than just an observation. This distinction is key: one relies on historical testimony of an ephemeral visual encounter, while the other is tied to the result of a specific capture attempt, though the status of that catch remains unverified.
