Armadillos and proteins

Two random facts of the day:

• the Dasypus genus of armadillos gives birth to four homozygous armadillo babies (that's identical quadruplets) every time they give birth.
• titin is the largest known protein with almost 3,000 kDa, which is about 5x10^-18 grams, which is, really, really small, but huge in the protein world.
