‘Octopus’
The genome of an octopus is similar to that of a human, and since it is an aquatic creature, it is difficult to take an intelligence test like that of a terrestrial animal.
I can't determine the exact intelligence level, but I'm sure it's at least smarter than a dog.
In fact, a documentary called ‘My Octopus Teacher’ was also produced on Netflix.
But because it looks like shit, it has been shunned in the West as a devil or a monster for a long time.
Cetaceans receive worldwide protection because they are highly intelligent, but this has nothing to do with them.
