What vessel was utilized during the 1932 observation of the Giant Dragonfish?

Answer

bathysphere

The context surrounding the 1932 sighting of the massive creature attributed to *Bathysphaera intacta* is intrinsically linked to the technology available at the time for deep-sea exploration. The observation was made while an expedition was actively utilizing a bathysphere to descend to significant depths. The genus name *Bathysphaera* itself is suggestive of this deep-sea origin, linking the creature's supposed name to the submersible used to spot it. While modern deep-sea investigation often relies on ROVs or net trawls, this particular seminal observation was conducted using the pressurized sphere known as the bathysphere.
