Hi again, Ewan and you're most welcome.
Your patience is always appreciated! : )
1) I would imagine that the guy would be a pretty big meal for the eel even a giant eel?
Yes, definitely. Even though the eel is quite large, a whole human man would be quite a big meal for it.
2) When the eel feeds on the guy’s chest area covered by the scuba gear, would the eel be able to tear it off whole?
As we know, the eel has many razor-sharp teeth, however, it would pull and tug at the scuba gear and not get it off whole, but in pieces; it would only take a few tries to free the scuba gear from the guy's body.
3) Once it starts to work its way down the body eating the chest, then stomach area, would there be a cavity formed at the stomach leading down to the pelvis, could it possibly push its head into the area covered in the tight orange swim trunks and feed on what’s in there that way?
It would start ripping at the area covered in the tight orange swim trunks and shred the trunks with it's teeth which would free them and they would float off.
4) Or how else might the eel feed on the area in the tight orange swim trunks?
After the trunks are shredded/removed, the eel would grab chunks of flesh from this area, with his sharp teeth. OR, the eel may just bite through the trunks, but spit out the material of the trunks OR he might ingest the trunks and won't have a problem digesting them due to the thinness of the material.
5) Would it be able to swallow down all of what’s in the front of the swim suit whole and in one go?
Yes, it would, having such a large mouth and those sharp teeth.
6) You say it will take 4 to 5 days for it to finish feeding. How long might it take the eel to eat and digest what had been in the trunks?
Well, yes, as I mentioned, it would take about 4-5 days to finish feeding; if m ight take the eel a few minutes to eat what was in the trunks and digest it within a day.
7) If another diver were to come exploring the wreck 7 to 8 days later, what might they find in the area of the eels lair?
Another diver might find remnants of a skeleton (bones) from the guy and other remnants of other humans the eel had eaten.
I hope this helped!
