It seems to be like some of the scales slightly off? If you are looking at the ladybird (ladybug) with the amoeba to the left, the amoeba isn't an order of the magnitude smaller - it would actually be visible by the human eye (bigger than a grain of sand)? Indeed, the amoeba seems the same size as the ladybird's foot? Similarly, this makes the bumblebee appear smaller than a human finger (the in the adjacent picture)…

I came to the comments to express surprise that amoebas were so large. It appears they vary wildly in size (as small as 2.3 micrometers... but up to 20 cm, or nearly 8 inches). https://en.wikipedia.org/wiki/Amoeba#Size_range

On the other side, wasps could be so tiny. like you could put thousands of them inside an amoeba volume.

"Megaphragma mymaripenne is a microscopically sized wasp. At 200 μm in length, it is the third-smallest extant insect, comparable in size to single-celled organisms. It has a highly reduced nervous system, containing only 7400 neurons, several orders of magnitude fewer than in larger insects."

Very cool. I was surprised that orangutans are described as being only 2 feet 9 inches tall, I think most are a bit larger. Maybe when sitting they're under 3 feet? From wikipedia: "females typically stand 115 cm (45 in) tall and weigh around 37 kg (82 lb), while adult males stand 137 cm (54 in) tall and weigh 75 kg (165 lb). The tallest orangutan recorded was a 180 cm (71 in)."

It's using the size of the ruler, matching the posture as shown in the image. A few keys over and there's a picture of a grizzly bear that says it is 1m or 3'4" tall. And maybe when it's on all fours, that's a typical measurement to the shoulders - its arm length, more or less.

That's much shorter than the human at 1.7m or 5'7". From just those numbers, you might think that a human would weigh more than a grizzly or take one in a fight: But when a bear stands on its hind legs, it's 2.4m/8' tall and can be 800 lbs, I'd have put a grizzly way further to the right.

If anyone wants to set this up to auto-run all the way to the right and then all the way back to the left, here is a vibe-coded (sorry) browser console script. Makes a great "screen-saver" if you kick off the script and then put your browser in full screen mode :)

    (function() {
        let direction = 'right'; // Start by going right
        let intervalId;

        function getCurrentAnimalName() {
            const animalDiv = document.querySelector('.animal-name');
            return animalDiv ? animalDiv.textContent.trim() : '';
        }

        function pressKey(keyCode) {
            const event = new KeyboardEvent('keydown', {
                key: keyCode === 37 ? 'ArrowLeft' : 'ArrowRight',
                keyCode: keyCode,
                code: keyCode === 37 ? 'ArrowLeft' : 'ArrowRight',
                which: keyCode,
                bubbles: true
            });
            document.dispatchEvent(event);
        }

        function autoScroll() {
            const currentName = getCurrentAnimalName();
            
            if (direction === 'right') {
                pressKey(39); // Right arrow
                
                if (currentName === 'Pando Clone') {
                    console.log('Reached Pando Clone, switching to left');
                    direction = 'left';
                }
            } else {
                pressKey(37); // Left arrow
                
                if (currentName === 'DNA') {
                    console.log('Reached DNA, switching to right');
                    direction = 'right';
                }
            }
        }

        // Start the interval
        intervalId = setInterval(autoScroll, 3000);
        
        // Log start message and provide stop function
        console.log('Auto-scroll started! To stop, call: stopAutoScroll()');
        
        // Expose stop function globally
        window.stopAutoScroll = function() {
            clearInterval(intervalId);
            console.log('Auto-scroll stopped');
        };
    })();

It claims a banana isn't technically living, but a banana has living cells so I'm not sure how accurate that is. I'm not sure when they're all considered 'dead' after harvesting though - maybe some wiggle room there.

My understanding is that picked fruits and veg are still alive [1], and often respirating [2]. This is a big component in figuring out how to refrigerate them at the optimal temperatures and atmospheric makeup.

The dynamic soundscape is delightful, as it subtly adds instruments and musical texture as you progress. And going back down the scale regresses it to simple again. Smoothly done. It reminded me of Operation Neptune (1991): each level starts with just one channel, probably percussion, and as you progress through the rooms it adds and removes more channels or sometimes switches to a different section of music. It is u…

Man I played Operation Neptune a lot when I was a kid. I wonder if it was the first game to do this style of adaptive music layering. It predates the iMUSE system used in LucasArts games like X-Wing and TIE Fighter.

For anyone curious, you can actually play it here: https://archive.org/details/msdos_Super_Solvers_Operation_Ne...
