livyatan vs sperm whale
For the moment, itâs hard to say if the two predators were direct competitors, since they may have swum in different parts of the Peruvian seas. Sperm whales have a unique organ in their heads called the spermaceti, and Livyatanâs was particularly large. The spermaceti is full of a waxy substance that was originally thought to be the animalâs sperm (hence the name). I think larger sperm whale could fan the smaller livyatan. The bite would have been the largest of any tetrapod (the animal group that includes mammals, birds, reptiles and amphibians). He says, âWe think that medium-size baleen whales, rich in fat, would have been very convenient prey for Livyatan .â. Similarly sized teeth had been found as early as 1877, providing tantalising hints of a giant, predatory sperm whale. Their owner remained an enigma. either of these relatives both work in pods for self defense.
The short, wide snout allowed it to bite more strongly with its front teeth, which were angled forwards to give a better grip on prey with curved bodies. Lambert thinks that the giant predator evolved to take advantage of this rich source of energy. Those that swam off the coast of Peru around 12 million years ago were hunted by a far bigger predator, a recently discovered animal with a very appropriate name: Livyatan. Reference: Nature http://dx.doi.org/10.1038/nature09067, If the citation link isnât working, read why here, Behold Livyatan: the sperm whale that killed other whales, The skull of Leviathan was big enough to swallow a human whole and had the largest bite of any tetrapod. It grow to about the same size as Leviathan but it hunts squid rather than other whales. In the last few years, other smaller prehistoric sperm whales have been found in Peru and Italy. Its temporal fossa â the shallow depression on the side of the skull â was enormous and could old huge jaw-closing muscles. At between 13.5 and 18.5 metres in length, it was no bigger than the modern sperm whale, but it was clearly far more formidable. In todayâs oceans, killer whales hunt other species of whales, working in packs to take down their much bigger prey. But the skull that matched those teeth has only just been found. At the depths, the energy expended during a hunt heats up the wax and melts it again.
But Livyatan probably didnât hunt for squid and probably wasnât a deep-diver like the modern sperm whale. Livyatan melvillei had a body length of 13.5 to 17.5 metres (44–57 ft), about the same as a modern adult male sperm whale. Their powerful teeth told us that these predators bit their prey in the manner of killer whales. Livyatan clearly grabbed its prey with a powerful bite, inflicting deep wounds and tearing off flesh as killer whales do, but with a skull three times bigger. Roughly the same thing but one has more teeth....seems legit. Livyatan melvillei, named after the Biblical sea monster and the author of Moby Dick author of Moby Dick, was a giant sperm whale that has just …
Vincent Marucut 2 39,207 views. The snout was short and wide, allowing it to bite more strongly with its front teeth and resist the struggles of its prey. The 85-footer might be 150+ tons, vs. just 55 tons for a 60-footer. 2020 National Geographic Partners, LLC. It used to be Leviathan until someone pointed out to the authors that the name had already been taken! livyatans are likely relatives to an orca or a sperm whale. Livyatan (live-ee-ah-tan) was a genus of raptorial sperm whale that lived in the oceans of Peru during the Miocene. But Livyatanâs mouth was full of huge teeth, the largest of which were a foot long and around 4 inches wide.  This was no suction feeder!
In light of this, other explanations become more intriguing. Well your regular Sperm whales jaws are very narrow. (Photo by O.Lambert), Leviathanâs teeth (A-C) could grow up to a foot long and were around 4 inches wide.
The teeth provided tantalising hints of a much bigger animal but they were never accompanied by an actual skull. Both have similar abilities but the livyathan has more weapons despite lacking a little in weight.
Welcome Guest. Livyatan for sure. Livyatan was at the very top of the food chain and it must have needed a lot of food. Livyatan wins due to far deadlier jaws. (Photo by G. Bianucci, O.Lambert, P.Loubry), The modern sperm whale is very different to its ancient cousin. Todayâs sperm whale has no functional teeth in its upper jaw and only small ones in its lower jaw (which are mostly used in fights). It could also boost the sperm whaleâs echolocation, allowing it to stun its prey with sound, or woo females (the maleâs organ is particularly big).
The short, wide snout allowed it to bite more strongly with its front teeth, which were angled forwards to give a better grip on prey with curved bodies. (Photo by G. Bianucci), Leviathanâs skull was clearly more robust and toothy than that of todayâs sperm whale, which feeds through suction. The digs werenât fruitful but the teamâs luck took a turn for the amazing at the very end. Livyatan's jaws were different. Click here to remove banner ads from this forum. The skull of Livyatan melvillei is 3 metres (10 ft) long. www.fanfiction.net/u/1613752/CrossoverMike. Yeah, I know I change my name every now and then. Unlike the modern sperm whale, Physeter macrocephalus, L. melvillei had functional teeth in both its jaws. Two of my favourite whales. Â âIn November 2008, on the last day of the field trip, my Dutch colleague Klaas Post discovered a very large cetacean skull,â says Lambert. Leviathan May Have Tangled With the Giant Shark Megalodon. The sperm whale might use it to control its buoyancy during a dive by pumping in cold water, solidifying the wax and increasing the density of its head. The skull is beautifully adapted to capture large, powerful prey. They only have teeth on the bottom jaw and have a weak bite force.
While modern sperm whales mainly eat squid, Lambert thinks that Livyatan used its fearsome teeth to kill its own kind â the giant baleen whales. It all depends on whether the max pre-whaling Sperm Whale bull size was in fact 85 feet, vs. just 60 feet. cetaceans are smart while working together and can flip … Livyatan would win here. And then it had much larger teeth. The case containing the spermaceti could be used as a battering ram during fights.

So just call me MP. livyatan cause off deadlier jaws..and about the ramming thing, livyatans are quite decent at ramming too! © 1996-2015 National Geographic Society, © 2015-
