Kraken ammonite (SciiFii)

The kraken ammonite (Giganticeras fluitarus) is a species of massive, floating ammonite from open seas, somewhat similar to a floating siphonophore jellyfish, that originally did not exist, but has since been created by SciiFii and introduced throughout the world's oceans to help boost biodiversity. The kraken ammonite is inspired by the similar-looking creature from The New Dinosaurs: An Alternative Evolution book of the same name. The only creature that can attack the kraken ammonite is a pelorus. The shell of the kraken ammonite is truly enormous, some specimens reaching 4 meters (13 feet) in diameter. The shell acts as a protective armor, as well as a float to keep the animal in the fertile surface waters. It has twelve tentacles that it spreads out around itself, and each of these has thousands of trailing fibers that are armed with stings and hooks. The whole arrangement forms a deadly net that covers an area of about 20 meters (67 feet) in diameter. The kraken will eat almost anything that becomes entangled in its traps, from microscopic floating plants, to fairly large fish. Many krakens often drift in the same area of productive waters, their floating shells acting as perches for migrant birds and pterosaurs. The conservation status of the kraken ammonite is Least Concern due to successful conservation efforts and the kraken ammonite's wide range.
