Tribe Kakinu'kake or Wing Arms
The Kakinu'kake are a tribe of Testoideans that live a majority of their lives at sea, preferring a life on a boat or on an island to the life on the mainland, though they do come to shore to hatch and raise the next generation. As such, some Kakinu'kake live on the mainland year-round to verify the safety of the young and ensure it is a safe haven from pirates. This tribe gets their namesake from their sea-turtle like appearance, though there are some that look more similar to leatherback sea turtles and protostegids, a type of sea turtle that grew to massive sizes.
Due to their flipper or wing-like arms, this tribe is known for its quick swimming speeds and ability to hold their breath for hours at a time.
