Category:Fibrous Object A on the Trailing Edge of Screw Blade R5
On some screw blades of No.1 torpedo, several kinds of fibrous objects were found. Object A, shown in photographs in this category is the most significant one. Some fibrous substances show radial symmetry like the sea anemone, but not vivid, and others fill in grooves or stretch out from there. I guess that these are degenerated remains of unknown marine creatures. The existence of these objects hadn't been evaluated in the investigation performed by JIG, and had been ignored by authorities even after their photographs had been published via well known online communities.
