Entire family fights narcs takers. Mother laid eggs like a snake does.

 Snakes don't have mammal moms who care for their young being loving and nurturing. They operate on primal instinct, basic needs for survival such as eating food, sleep, work, sex. 

Brains are not developed the same as those beings who care for their babies almost selflessly. 

Communications skills are limited to the most basic functions, FEAR being the primary emotion.
