6. Ragfish (Icosteus aenigmatic)
Ragfish start their lives as eggs, which are incubated inside their mother’s body until they are ready to hatch. Once they hatch, they are on their own. They must fend for themselves immediately, as their mother does not stick around to care for them.

No matter how difficult their start in life may be, ragfish never give up. They will fight tooth and nail to survive, even if the odds are against them.
