So, been a while since I posted Rahi so have some of my recent ones. The Kahu and Kikanalo have been updated recently with new wings and feet, tho that's it.
Tullo Fish Tropical fish rahi found in the oceans around Okoto Nui. They are common prey for numerous rahi and animals.
Khabew Large beetle-like Rahi. They are temperamental and very territorial often fighting with each other or anything else that enters their territory. Bone Hunters have been known to catch them to pit against each other or other rahi for fun.
Tarakava Semi-aquatic lizards. Tarakava are massive, dangerous predators able to punch with enough force to break solid protodermis.
They dig dens for themselves under water, gathering air weed to breath. Some have been known to take stones with coral polyps on them and placing them at the mouths of their dens intending to use the burgeoning coral to draw in small fish to use as bait for larger prey.
Whali Small bugs found almost everywhere. Many matoran consider them cute.
Fikou Nui Massive, venomous Spider-rahi that stalk Okoto-Nui's forests, jungles, and caverns. The only spiders feared more than them are the Vizorak.
Size comps
I always thought it was weird that something that spent alot of time under water didn't seem like it could swim, so I corrected that with my Tarakava build. I like the idea that tropical fish will school around Tarakava for protection.
