This crocodile needlefish swam up to check me out one day when I was snorkeling. These are large fish and sometimes, when I see them, I mistake them for great barracudas. A somewhat disturbing fact about crocodile needlefish is that, if they become alarmed, particularly at night, they can turn on whoever has frightened them and drive their beak into that person. The wounds inflicted can be very serious and deaths have been recorded. Mostly though, when I’m snorkeling, they just cruise by and take a non-threatening look.
