Inagawa are small Carapaceon's that reside in areas near shorelines where they are able to feed off of a variety of small fish near the shores edges, these areas are the Jungles and the Deserted Isle. Inagawa are usually found in small packs of up to 3 Inagawa, they are not a big enough threat for a large monster in that area but can be irritant for hunters as they travel through their areas.
Inagawa are the food source for many sea based monsters such as Plesioth and its Subspecies as they dwell too close to the waters edge when they need to eat and they become an easy meal for these monsters due to this. For a weak hunter their claws can cause some minor damage but when they are in a pack it can be more deadly as they will all be able to apply damage to the hunter and become a great distraction when the Hunter is trying to slay a larger monster.
