Sperm Whale (Bull) - Physeter macrocephalus The sperm whale, Physeter macrocephalus, is a marine mammal species, order Cetacea, a toothed whale (odontocete) having the largest brain of any animal. The name comes from the milky-white waxy substance, spermaceti, found in the animal's head. The sperm whale is the only living member of genus Physeter. The now outdated synonym Physeter catodon refers to the same species. It is one of three extant species in the sperm whale superfamily, along with the pygmy sperm whale and dwarf sperm whale. A mature male can grow to 20.5 metres (67 ft) long. It is the largest living toothed animal. For large males, the head can represent up to one-third of the animal's length. It has a cosmopolitan distribution across the oceans. The species feeds primarily on squid but to some extent on fish, diving as deep as 3 kilometres (9,800 ft), which makes it the deepest diving mammal. Its diet includes giant squid and colossal squid. The sperm whale is the largest toothed whale, with adult males measuring up to 20.5 metres (67 ft) long and weighing up to 57,000 kilograms (56 long tons; 63 short tons). Average sizes for a Bull: Length, 16 metres (52 ft) Weight, 41,000 kilograms (40 long tons; 45 short tons). ![]() Carcharocles chubutensis Carcharocles chubutensis is a prehistoric megatoothed shark that lived during Oligocene, Miocene, and Pliocene epochs, approximately about 28 - 5 million years ago.This shark is considered to be a close relative of another prehistoric megatoothed shark, C. megalodon. However, as is the case with C. megalodon, the classification of this species is disputed. This species is also known from fossil teeth and some fossilized vertebral centra. Shark skeleton is composed of cartilage and not bone, and cartilage rarely gets fossilized. Hence, fossils of C. chubutensis are generally poorly preserved. Although the teeth of C. chubutensis are morphologically similar to teeth of C. megalodon, they are comparatively slender with curved crown, and with presence of lateral heels feebly serrated. Fossils of this species have been found in North America, South America, Cuba, Puerto Rico, Africa, and Europe. C. chubutensis was larger than C. angustidens. Teeth of C. chubutensis can approach 130 mm in slant height (diagonal length), which according to size estimation method proposed by Gottfried at al, in 1996, indicate 12.2 m (40 ft) long specimen. ![]() I was making this, and then the request was deleted! |

Well crap, I just did some research on the Livyatan vs. Meg debate and now I'm not sure about this one either lol. If the shark was 12m, and if it did approach the whale under perfect circumstances from below, delivering a strong bit to the tail of the whale, therefore immobilizing it and allowing it to bleed out; under this perfect scenario the shark would win. But besides this, I change my vote to the sperm whale. It's size alone should, in most cases, deter the shark. |

Of course, in real life, not even a 12m shark would dare to approach a bull sperm whale (except by ambush). However, in these hypothetical match ups, the combatants are willing to fight to the death, so neither is allowed to leave the fight. Anyway if the shark was really 12m (which seems unlikely at this point), then it wins. However, if the shark is actually smaller (say 9 or 10m), then the whale wins because it would be 4 times heavier than the shark and the shark will even be vulnerable to the whale's jaws at these sizes. |

Man, in a hypothetical scenario where the two are facing off and determined to go at each other, the 12m shark would have no chance. What is it supposed to do against a 40 ton whale ramming it at 40km/h? Bite it? Its like biting a boxing glove about to smash your face. Now in reality, I don't know how the whale would behave. Honestly SW are a bit of a mystery..as a rule, they did not put up much of a fight against whaling boats, even though they could've easily wiped them out. So honestly I don't know how would they react to the shark. But something tells me they didn't evolved next to whale killer sharks without knowing how to deal with them.

The shark could outflank the whale. Wouldn't a 12m, 20 ton shark be more agile and faster than a 16m, 40 ton whale? And won't the whale need to swim and hit the shark from some distance in order for an effective ram? Edit: the modern whalers from the Indonesian village of Lamalera hunt Sperm whales quite easily, with small, weak-looking boats. Edited by Lightning, Mar 23 2018, 03:17 AM.

Sharks aren't more agile than cetaceans..nor are they faster(Mako shark being the outlier)..Size isn't necesarily a factor, since for example an orca can outrun a gws easily. Also SW can maintain high speed for far longer. If a shark flanks, the whale could keep charging. Shark has the advantage of turning ratio, but it basically can't keep up enough to close in for a bite on the weak area. But again it's just a theory and fantasy..sharks aren't fighters by nature. If they are attacked, they will normally retreat. And sw would not persist on trying to kill the shark, he would be happy to simply deter it. Edited by Sam1, Mar 25 2018, 06:30 PM.

Hhmmmm honestly I don’t know, I may favour the Whale. Edited by Mammuthus, Mar 23 2018, 06:38 AM.

OK, we need to consider: 1. when has a Bull Sperm Whale ever killed anything impressive? 2. will the Shark line up for a headbutting contest with the Whale? |

Yeah that's the basic premise. Depends on the definition of impressive. They kill what they eat and nothing more. Probably some occasional 500+kg squid or once in a blue moon, a megamouth shark, is their limit in that regard. While commonly perceived as timid and slow giants, SW aren't just a slow squid pickers. Males will often clash with one another, using the jaws. The fact that they typically do not put up much of a fight against whalers is a complex mystery that doesn't necessarily mean they would act similarly against a shark. I can think of some theoretic ways the whale could kill the shark - ramming it at full speed and at perfect angle, holding it until the shark drowns, and tearing off the pectoral fin.(resulting in shark being unable to swim and eventually drown) But in reality, again it all just sounds more like a fantasy. Otoh, the shark kills something only if it wants to eat it. If its target is turning against it and forcing it into evasion, shark is most likely to retreat and move on. |

The first point is quite an interesting actually, but yeah I don't think they have ever killed anything that impressive. For now my opinion on this matchup is still relatively neutral. |

Well, it of course depends on how you frame the question. They have never killed anything especially impressive, but if you frame the question a bit differently to "when has a Bull Sperm Whale ever destroyed anything impressive?" they suddenly become the most formidable creatures currently alive. |

My post was more pointing in the direction of the former. |

Well tbh that whale was probably over 100 tons of pure primal rage. We're talking about average specimens here. |
