Notice that Miss is not an abbreviation, so we don't put a period after it. Ms. is not an abbreviation, either, but we do use a period after it  probably to keep it consistent with Mr. and Mrs. The plural of Mr. is Messrs. (We invited Messrs. Carter, Lincoln, and Ford.) The plural of Dr. is Drs.(We consulted Drs. Carter, Lincoln, and Ford.) The plural of Mrs. is Mmes or Mmes.lso, we do not use a period with such abbreviations except for in. when it might be confused with the preposition in. When the term of measurement is used as a modifier, we put a hyphen between the number and the term of measurement: a 15-ft board, a 6-lb line, etc.

The Greenland shark is the world's new champion of vertebrate longevity. Scientists just named the longest-living species of vertebrate animal. It's a creature that can live up to 400 years old, almost twice the lifespan of the oldest giant tortoises or bowhead whales, nature's next runners-up. These lords of longevity are the Greenland sharks, Somniosus microcephalus.
