I doubt that. If I, as an itty bitty fishie, saw this huge ponderous,
protuberances all over, thingie moving towards me, four huge fins and
a "head" that moves independently, I'd have serious doubts about my
immediate future.

Conversely, because I don't recognise this self same "thing" as a
predator of my species, I might just ignore it and that is (perhaps)
what happens.

I've, and I'm sure lots of others of us have similarly, been with
seals not generally exposed to divers. First they treat you curiously,
show off, then they wonder whether you might be good enough to eat.

Most first do the "taste test" on your fins but one came up to my arm
with an avaricious gleam in its eye. Since that arm had already been
"taste tested" by a particularly large moray many years before it got
withdrawn pronto.

True, but these are very specific instances in very specific places
which are very cold, which invariably refer to schooling fish and
which are not the natural habitat of the average u/w photog, even the
"unaverage" one.

Unless your name happens to be Amos Nachoum, inter alia.

This is getting seriously Off Topic, so I'm withdrawing from the fray.

Cheers,

Christian
