Coelacanthgender is a gender where you loose your gender and it goes extinct. It goes away for a long period of time and randomly comes back. Your gender may show little signs of coming back but you don't notice. After showing signs of gender your gender pops up. Also where your gender comes and goes then finally goes extinct.
