Pinnipeds are smart like dogs. Dolphins are smart like primates.
- stinos 11y agoDo you have a source for this? Also, what primates exactly do you mean? There are huge differences of smart within the primate category, e.g. monkeys vs humans.
- vlehto 11y agoHumans actually. "The brain to body mass ratio in some members of the odontocete superfamily Delphinoidea is second only to modern humans, and greater than all other mammals" https://en.wikipedia.org/wiki/Cetacean_intelligence https://en.wikipedia.org/wiki/Cetacean_intelligence

- Natanael_L 11y agoNeuron interconnectivity might be more important than plain neuron count. So that could be an advantage.
- pvaldes 11y agoDolphins are smart like dolphins. They do not have hands as we have, they have a language really complex, cant talk each other being a several km of distance without any gadget, can voluntarily decide to stop to breath (and move the blood only to the vital organs for a half hour or more), and can "see" perfectly in the dark. Not comparable intelligences.
