When a species evolves from living in water to living on land it’s called terrestrialization, and it’s not an easy task. Yet crabs keep making the jump from sea to shore. Why? And how do they do it?

      @The Hondo It’s a gimmick. Notice how they don’t play any samples of the music in the incorporated ad for fear of the sponsor demonetizing the video and stealing the ad revenue back.

    I really really want crabs to create internal skeletons by actually creating bones or internalizing their exoskeleton, with that they have more support for muscle and fleshy outsides... The pincers may still have the exoskeleton making it look like they are using gloves

    A few weeks ago there was said that animals turn into crabs, now these "ascend" to the surface. But there are hardly any landcrab animals where spiders are, right? Even though there's a weaving scorpion. But islands like Guam would have gotten their many spiders from deforestation or other "overuse" i guess, spiders as "police animals" are a sign the environment is supposed to heal. I just thought of several islands that had gotten degenerated so no sweetwater (d)rains down there

    My main complaint with Scishow is that I'd much prefer to see footage clips of what you're talking about instead of just a still image of the animal and then y'all talking and waving your hands about. I do like to watch y'all talk about the subject but many times you mention some really cool stuff I'd like to see.
