X is for Xenarthra

XThe suborder Xenarthra is only found in the Americas and includes a group of placental mammals. This sub order is represented by anteaters, tree sloths and armadillos.

“Xenarthrans share several characteristics not present in other placental mammals. The name Xenarthra, which means “strange joints”, was chosen because their vertebral joints have extra articulations and are unlike those of any other mammals — a character referred to as “xenarthry”. The males have internal testicles, which are located between the bladder and the rectum. Also, xenarthrans have the lowest metabolic rates among the therians.”
