Livyatan

Livyatan melvillei is a species of carnivorous whale that lived the same era as the Megalodon and reappeared alongside its rival in the Prehistory Pelago's oceans. It is an intelligent animal with sharp teeth and deadly strike capabilites and also happens to be able to communicate with telepathy if it makes a friend. They are agile and very successful predators only rivaled by the megalodon and Ceadeus and the Mosasaurus. as a Tanker class creature(Subclass: All Rounder), Livyatan reaches lengths of 16.8 meters long. during wars they cut A-10 warthogs clean in half with their teeth.

## Biology

Since only the skull of *Livyatan* is known, the ratio of the skull to the body length is unknown, as is total body length. The total length of adult *Livyatan* is estimated to have been about 13.5 m (44 ft) when using the modern sperm whale for scaling, and 16.2–17.5 m (53–57 ft) when using the raptorial *Zygophyseter* for scaling; scaling achieved by measuring the head-to-body ratios. by comparison, the modern sperm whale measures on average 11 to 16 m (36 to 52 ft). It has been estimated to weigh 57 tonnes (62.8 short tons) based on the length estimate of 17.5 m (57 ft). The large size was probably an anti-predator adaptation, and allowed it to feed on larger prey. *Livyatan* is the largest fossil sperm whale discovered, and was also one of the biggest-known predators, having the largest bite of any tetrapod.

The holotype skull of *Livyatan* was about 3 m (9.8 ft) long. Like other raptorial sperm whales, *Livyatan* had a wide gap in between the temporal fossae on the sides of the skull and the zygomatic processes on the front of the skull, indicating a large space for holding strong temporal muscles, which are the most powerful muscles between the skull and the jaw. The snout was robust, thick, and relatively short, which allowed it to clamp down harder and better handle struggling prey. The left and right premaxillae on the snout probably did not intersect at the tip of the snout, though the premaxillae took up most of the front end of the snout. Unlike in the modern sperm whale, the premaxillae reached the sides of the snout. The upper jaw was thick, especially midway through the snout. The snout was asymmetrical, with the right maxilla in the upper jaw becoming slightly convex towards the back of the snout, and the left maxilla becoming slightly concave towards the back of the snout. The vomer reached the tip of the snout, and was slightly concave, decreasing in thickness from the back to the front. A sudden thickening in the middle-left side of the vomer may indicate the location of the nose plug muscles. Each mandible in the lower jaw was higher than it was wide, with a larger gap in between the two than in the modern sperm whale. The mandibular symphysis which connects the two halves of the mandibles in the middle of the lower jaw was unfused. The condyloid process, which connects the lower jaw to the skull, was located near the bottom of the mandible like other sperm whales.

Unlike the modern sperm whale, *Livyatan* had functional teeth in both jaws. The wearing on the teeth indicates that the teeth sheared past each other while biting down, meaning it could bite off large portions of flesh from its prey. Also, the teeth were deeply embedded into the gums and could interlock, which were adaptations to holding struggling prey. None of the teeth of the holotype were complete, and none of the back teeth were well-preserved. The lower jaw contained 22 teeth, and the upper jaw contained 18 teeth. Unlike other sperm whales with functional teeth in the upper jaw, none of the tooth roots were entirely present in the premaxilla portion of the snout, being at least partially in the maxilla. Consequently, its tooth count was lower than those sperm whales, and, aside from the modern dwarf (*Kogia sima*) and pygmy (*K. breviceps*) sperm whales, it had the lowest tooth count in the lower jaw of any sperm whale.

The most robust teeth in *Livyatan* were the fourth, fifth, and sixth teeth in each side of the jaw. The well-preserved teeth all had a height greater than 31 cm (1 ft), and the largest teeth of the holotype were the second and third on the left lower jaw, which were calculated to be around 36.2 cm (1.2 ft) high. The first right tooth was the smallest at around 31.5 cm (1 ft). The Beaumaris sperm whale tooth measured around 30 cm (1 ft) in length, and is the largest fossil tooth discovered in Australia. These teeth are thought to be among the largest of any known animal, excluding tusks. Some of the lower teeth have been shown to contain a facet for when the jaws close, which may have been used to properly fit the largest teeth inside the jaw. In the front teeth, the tooth diameter decreased towards the base. This was the opposite for the back teeth, and the biggest diameters for these teeth were around 11.1 cm (4.4 in) in the lower jaw. All teeth featured a rapid shortening of the diameter towards the tip of the tooth, which were probably in part due to wearing throughout their lifetimes. The curvature of the teeth decreased from front to back, and the lower teeth were more curved at the tips than the upper teeth. The front teeth projected forward at a 45° angle, and, as in other sperm whales, cementum was probably added onto the teeth throughout the animal's lifetime.

All tooth sockets were cylindrical and single-rooted. The tooth sockets increased in size from the first to the fourth and then decreased, the fourth being the largest at around 197 mm (7.8 in) in diameter in the upper jaws, which is the largest of any known whale species. The tooth sockets were smaller in the lower jaw than they were in the upper jaw, and they were circular in shape, except for the front sockets which were more ovular.

The fossil skull of *Livyatan* had a curved basin, known as the supracranial basin, which was deep and wide. Unlike other raptorial sperm whales, but much like in the modern sperm whale, the basin spanned the entire length of the snout, causing the entire skull to be concave on the top rather than creating a snout as seen in *Zygophyseter* and *Acrophyseter*. The supracranial basin was the deepest and widest over the braincase, and, unlike other raptorial sperm whales, it did not overhang the eye socket. It was defined by high walls on the sides. The antorbital notches, which are usually slit-like notches on the sides of the skull right before the snout, were inside the basin. A slanting crest on the temporal fossa directed towards the back of the skull separated the snout from the rest of the skull, and was defined by a groove starting at the antorbital processes on the cheekbones. The basin had two foramina in the front, as opposed to the modern sperm whale which has one foramen on the maxilla, and to the modern dwarf and pygmy sperm whales which have several in the basin. The suture in the basin between the maxilla and the forehead had an interlocking pattern.

Livyatan is the first instance of a real carnivorous whale in the planet.
