Not P but Moby-Dick (3)

[Mike Jing]

The following excerpt is from Chapter 6:

In these last-mentioned haunts you see only sailors;  but in New Bedford,
actual cannibals stand chatting at street corners;  savages outright;  many
of whom yet carry on their bones unholy flesh.  It makes a stranger stare.

What does "yet carry on their bones unholy flesh" mean here? All five
previous Chinese translations I have consulted interpreted it as being
naked, but I don't think it's correct.
