I hate the fact that orcas are the apex marine predators of today. Such a boring and lame creature, they are oversized dolphins with panda patches and hunts in pods like pussies. Why? I thought everything in nature was perfect but killer whales as the top ocean predator does not feels right. Not so long ago there were giant mega-toothed sharks and macroraptorial sperm whales with ugly, monstruous heads in our oceans. We were supposed to still have this, but we're stuck with panda dolphins that perform circus tricks instead (literal CLOWNS).
>>5129501>controlled aggressiveness??They kill seals and other dolphins/porpoises for fun.
>>5129650They also attack boats for no reason
>>5122217Dunkleosteus was the coolest oceanic apex predator
>>5129419>You can't point out that we completely ignored the original point of the post because...you just can't okay?!?!?Noted and ignored. If your response to a statement about theropod macropredators is "penguins and...umm...therizinosaurus!!!" you missed what the statement was about. >>5128290>Their skulls are completely different. Carnotaurus had a short, deep skull with much smaller teeth and very high cranial kinesis. It was adapted for relatively quick, weak bites and swallowing large chunks of food. Allosaurus was the complete opposite, and that’s not even comparing its giant meathook claws to Carnotaurus’ useless mittens. You may as well say that Homotherium and Xenosmilus “share the exact same skull design”They are visually different due to coming from distinctly separate lineages, but their function is the same. Carnos "Quick weak bites" are the same thing Allo was doing, I'm not sure how you think Allo was the opposite. Both animals have curved serrated teeth propped up on a long neck with an "S" curve, for making rapid strikes with a narrow skull. (Carnos is shorter length wise, but they are both narrow when it comes to width) The only reason Allo differs from Carno is because Carno is a derived late Cretaceous theropod while Allo is a basal "transitionary" form between the two small/large theropod body plans. Allos claws are also highly overstated. Yes they were usable, but they are hardly like Megaraptoran arms. The animal would still be using it's mouth for the majority of it's hunting strategy. There's a reason nearly every large theropod lineage in the late cretaceous has atrophied arms, they are simply less important for dispatching large prey.
>>5130302>If your response to a statement about theropod macropredators is "penguins and...umm...therizinosaurus!!!" you missed what the statement was about.How so?

>>5129089rolling for next spinosaurus discovery to be evidence that it could close its throat similar to crocodiles, dolphins, seals, and penguins. would also finally solve a current discrepancy with lipless spinosaurus being unable to seal off its oral cavity from the air, crocodiles get around this by closing their throats so maybe spinosaurus did the same thing.

is being extra cute an evolutionary advantage? I wouldnt want to eat one cause it's so cute.
>>5130427no. half of these species of guys are near extinct because the humans on the little island these little guys are on too, just hunt them to perpetuity

A few of the remarkable things about this frog:>When threatened, they were capable of gliding through the air by leaping from their perch and fully stretching their massive webbed hands and feet.>The tadpoles feed directly from the father – During the day, the males back into the tadpole-filled water of the tree holes and remain in that half-submerged state until night. During this time, the tadpoles swim around them, rasping small pieces of skin from their fathers’ backs and eating them.>The last known observation of the frog in the wild was that of a single male heard calling (but not seen) in 2007.https://www.youtube.com/watch?v=i4eZIkBGMjM

What is /an/'s favourite nature documentary? For me it's Attenborough's "The Life of X" collection. I've rewatched it recently, and the thing I like about it the most is that it puts more emphasis on life's diversity and how various creatures are adapted to their environment, rather then to try to show a story or a pretty picture, which is what most documentaries do.

I enjoy watching wildlife/paleo docs on Youtube

When I was a kid my dad would always take me to rock pools and I'd lift rocks up and look at what I could find. I found a few blue ringed octopuses but my dad had instilled a fear of them in me so I never touched them but it seemed like a lot of trust for a kid. He used to tell me that if I got bit I'd be dead and there's nothing he could do about it.
>>5125344they look harmless

He has one of largest red blood cells and largest DNA sequences of any animal. Be nice to him.

>>5126448>they'd have all been exterminated by cavemen.Early human hunter-gatherers are a major red herring for the extinctions and changes in the last glacial maximum. At most, they were a domino in a large set of events that were gonna happen anyways.After the agricultural revolution though, anything is possible.
The problem with blue whales is theyre huge and insanely impressive but they live in the open ocean so no one ever sees them and its basically like they dont exist.They're hard to even film and even when filmed never have anything near them as size reference so its really really hard to even tell how big they are. In most footage a blue whale and regular whale swimming around functionally look like the same size or whatever.
>>5128501some maniacal billionaire needs to build an aquarium large enough to display one
Sperm whale vs Colossal Squid is cooler than T-rex vs Trike
>>5129498Sperm whale always wins though
As a pet owner I'd be very concerned about any animals being outside in general.No shot this doesn't backfire and kill some native species.

Good. Fuck cats and dogs
>>5128460many based threads to be found for those who look
>>5078915Cats DO fall below birds in any legitimate hierarchy.
>>5125849dingoes rock
Cats are significantly less intelligent than dogs. They are slightly less domesticated and have the tendencies that come with that (more persistent independent action and innate skills that help them in the wild, reminiscent of the ways chimpanzees and orangutans outperform humans on select tasks), but overall, have inferior cognition and a less rich inner world, while dogs are complex social animals with more going on inside their head.https://www.scientificamerican.com/article/dogs-when-you-count-neurons-have-a-lot-more-than-cats/Some dog breeds, such as german shepherds, can have over 800 million cortical neurons, twice as much as the average mid sized mutt.Therefore, since dogs psychological needs are greater than their suffering is deeper, public policy should prioritize canine well being, while making concessions to a clean society and the natural order and regulating cats as if they are simply less aware of their situation anyways, because they are.Proposed changes:Dogs must have at least 1/4 acre to roam around in at any given timeIt is illegal to crate a dog except under less than ordinary circumstancesDogs must be allowed to roam in a fenced in park at least once a week, for at least an hour, if their behavioral tendencies allow itSpay and neuter must be delayed until sexual maturity for dogs to ensure proper cognitive developmentDogs must be taken to the vet for a physical and psychological wellness check at least one every three monthsCats must be kept indoorsCats must be spayed and neutered as soon as possible to prevent overpopulationWhen roaming cats are third class citizens akin to escaped rabbits
