The teleosts (from Greek for “complete bone”) are an infraclass of ray-
finned fishes that arose in the Triassic period. Making up 96 percent of
all known fish species, this diverse group includes about 40 orders and
448 families. They inhabit oceans at all depths, estuaries, rivers,
lakes and swamps. They range in size from the giant oarfish, measuring
25 feet (7.6 m) or more, and the ocean sunfish, weighing over 2.2 short
tons (2 tonnes), to the male anglerfish Photocorynus spiniceps, just
0.24 inches (6.2 mm) long. Teleosts can be torpedo-shaped, flattened
(vertically or horizontally) or cylindrical, and some, like the
anglerfish and seahorse, have unique shapes. They can protrude their
jaws, enabling them to grab prey and draw it into their mouth. Depicted
in art over the centuries, teleosts are economically important to
humans. They are harvested for food, captured for sport, kept in
aquariums, and used in research, especially in the fields of genetics
and developmental biology.

Wikiquote quote of the day:
Perhaps I did not succumb to ideology … because I have never
seen myself as a spokesman. I am a witness. In the church in which I was
raised you were supposed to bear witness to the truth. Now, later on,
you wonder what in the world the truth is, but you do know what a lie
