Lions are better predators than crocodiles, they have a better success rate. Crocodiles are just ambush predators, lions are more active. They can chase down prey, hunt in packs. They can scavenge, chase hyenas from a kill. Crocs' domain is only the water. And as for them beating "my precious mammalian carnivores", a pride of lions could beat a croc. Few crocs are big enough to challenge one lion. Livyatan died out for some reason, doesn't mean that Meg was the apex predator and out competed it. The Great White outlasted Meg, does that make it the more dominant predator? No. Yeah a pride of lions can beat a (small-medium sized) croc, but a two ton monster is immune to predation. A pride wouldn't even try. You are getting dominance, and success confused. The Great white is not a more dominant predator than Megalodon, but it is the more successful one, as it has survived. |

Well, I doubt that was the intention. The whole question becomes stupidly obvious when you include entire Kingdoms in "cold-blooded". Why would we have such a thread? And for the sake of argument, why don't we just consider vertebrates? so your saying that its obvious that ectotherms > endotherms, so you want the debate to be vertebrates ectotherems vs endotherms? (which as far as I know are always vertebrates) |

You are considering plants now? How can a plant be cold blooded? I mean doesnt an organism have to be "blooded" in the first place before it can be defined as warm or cold? This is my point on inverebrates, do they really have what we would define as blood?
Can haemolymph be considered blood? It has components of blood and other bodily fluids aswell.
Many arthropods generate their own body heat by shaking or shivering to create body heat through friction, thus being in a sense endothermic.

Warmblooded and coldblooded are just laymans terms for ectothermic and endothermic.
I didnt know that about arthropods, Interesting.

I actually never said plants were ectothermic I was simply saying that they can be used in the thread, as long as you back up what you say you wont get any debate from me on the subject.

HA! The entire Earth biosphere depends on plants.
But, let's have a fair debate about vertebrates, shall we?

Im willing to discuss this based solely on vertebrates....
If were going to debate this from the position of the entire kingdom of Animalia its going to get drawn out, there is much diversity class to class.

Your right and do you know why? because niether system is truly superior to the other, which is what ive been saying all along. |

I certainly wouldnt place trees at the bottom of the foodchain. Animals that feed on parts of trees are almost strictly symbiotic.

Crocs are the most famous examples of that. Some fish do also.
