Migas Archipelago

Migas Archipelago (ミガー諸島) is an archipelago on the. It is known for possessing some of the most dangerous creatures of all of the oceans. It is also a swamp biome. It is located in the second half of the Grand Line, the "New World" (新世界).

However, for as many dangers as the island may hold, it possesses several natural treasures, such as medicinal herbs that act as antibiotics, painkillers and anti-inflammatories.

Michiwani
Michiwani (道鰐): A rare species only found in this archipelago. These giant crocodiles gained their names over the fact that their backs are shaped like roads, allowing those that are careful to pass. Reaching the end of a Michiwani's back holds a big challenge to those that are careless: their backs hold extremely sensitive nervous ends and those that wish to travel have to meet certain conditions: they must be barefooted so the shoes don't hurt the crocodile's back, they must also be light in weight and only one person can go at a time. Michiwani are surprisingly big: their mouths, when fully open, can reach the height of an average adult, just in their first years of life. An adult one's jaw opening can reach the size of someone like. Their body is also several times the size of a human, being about half the size of a giant. Due to their giant nature, they can easily kill any careless adventurer. However, due to their big size and power, they lack mobility, as their leg muscles were not developed during their evolution as a species, and instead, the growth of the muscles was focused on their mouth and tail.

Salahebi
Salahebi (山椒魚（サラ）蛇): Salahebi somehow resemble a hybrid mix of a salamander and a snake. They have a range of colors, but are more commonly seen with a bluish complexion. These are completely poisonous, having not only poisonous skin (like a salamander), as they secrete poison from their fangs (like a snake) and breath. They can also strangle their victims. Apparently, if they are killed, their meat carefully treated and prepared, they are no longer poisonous and can be eaten. Some say their meat is delicious, but a bit tough.

Trivia

 * The archipelago's name, "Migas", means "crumbs" in Spanish, due to the fact that, in a bird's eye view, the set of islands resemble bread crumbs over a table.
