Producing or giving birth to organisms with hair; relating to or characteristic of animals that bear hair.
From Latin crinis (hair) plus parere (to produce or bear), creating a biological term that describes animals as 'hair-producing' or 'hair-bearing,' parallel to ovipаrous and viviparous.
While we use 'viviparous' and 'ovipаrous' regularly in biology, 'criniparous' is almost never used because 'mammal' is simpler and more understood—this shows how scientific language follows the path of least resistance, adopting or avoiding terms based on what actually gets used in practice.
