Feeling Groovy in Little Cayman

I was in Little Cayman this past May, and a lyric hit me on the first dive: “Slow down, you move too fast. You got to make the morning last.” I had been invaded by Simon and Garfunkel’s 1966 hit “The 59th Street Bridge Song (Feelin’ Groovy).”

Once in a Lifetime

Like many octopuses, the female greater blue-ringed octopus (Hapalochlaena lunulata) is a semelparous animal, which means she reproduces once and then dies.
