Arciteuthis

Arciteuthis is the name of a remote animal native to the waters of River Nesraken.<ref name="Combination of the words 'Ness' (Loch Ness Monster) and 'Kraken' (the colossal squid/octopus featured in sailor stories) The Arciteuthis is a large cephalopod which eats boats and other river-faring objects on top of the water, as well as other sea creatures such as the Nesraken serpents. The animal can only be visited if one stands on the shores of the Nesraken Island, located in the middle of the river. From there, a viewer can watch the many tentacles of the large cephalopod rise up from the water and do amazing things.
