We still don't have a good way to measure human intelligence, let alone non-human intelligence. And yet there are some animals whose intellectual abilities are undeniably strong — maybe even as strong as ours. Which animals do you think might one day turn out to be our mental equals?

Crows and ravens use tools, while octopuses seem to communicate by changing the color patterns on their skin. Many apes have learned to use sign language, and can have rudimentary conversations with their human companions. And then there are the social insects, like ants, who may be dumb as individuals but as colonies are able to farm, build cities, and wage wars. Plus there are many more.
Tell us which animal is your candidate for possessing human-like intelligence, and include pictures or video if you can!
