Distribution and Range
Turritopsis is believed to have originated in the Caribbean but has spread all over the world, and has speciated into several populations that are easy to distinguish morphologically, but whose species distinctions have recently been verified by a study and comparison of mitochondrial ribosomal gene sequences. Turritopsis are found in temperate to tropical regions in all of the world's oceans. Turritopsis is believed to be spreading across the world as ships are discharging ballast water in ports. Since the species is immortal, the number of individuals could be rising fast. "We are looking at a worldwide silent invasion", said Smithsonian Tropical Marine Institute scientist Dr Maria Pia Miglietta.

There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
“They didn’t know
how
my heart woke
to a range and measure
of song
I hadn’t known.”
—Hilda Doolittle (1886–1961)
