From lemurs to lizards, ants to amphibians, sharks to chickens, hundreds of animals “play dead” as a survival tactic. But how and why do animals do this? Tierney Thys explains how this curious behavior, known as tonic immobility or TI for short, can be used as a defense or offense.

    Mrs Richards "I paid for a room with a view !"
    Basil: (pointing to the lovely view) "That is Torquay, Madam."
    Mrs Richards: "It’s not good enough!"
    Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?…"
    Mrs Richards: "Don’t be silly! I expect to be able to see the sea!"
    Basil: "You can see the sea, it’s over there between the land and the sky."
    Mrs Richards: "I’m not satisfied. But I shall stay. But I expect a reduction."
    Basil: "Why?! Because Krakatoa’s not erupting at the moment ?

    Apparently chickens can tell when something is looking at them, but I feel like my cats can also sense this and wake up the instant I look at them.

    I saw A possum playing dead once. My dogs where making A fuss so I went to check on them. I found playing tug of war with what I thought was a dead possum. I broke up their fun and got a shovel used it toss over my fence. I went out later and was going bury it but it was gone.

    Catatonia is a group of symptoms that usually involve a lack of movement and communication, and also can include agitation, confusion, and restlessness. Until recently, it was thought of as a type of schizophrenia . And I guess it is a way for preys to escape from their predators

  32. gabi.n_art on December 11, 2021 at 9:48 am

    Can we get a ten hour loop of the opossum walking please it’s so cute

    I still don’t get why they do it

  35. B. Goodfellow on December 11, 2021 at 9:54 am

    “Silence is the most powerful scream”. Great statement! I know that when the emergency services attend an accident scene, it’s the silent people they go to first, as if you can scream, you are first and foremost conscious, but those who appear conscious, but remain silent and still, they may well have serious internal injuries. Well, that’s what I was told in a first aid session. 🙏🙏🙏

    The short yellowish dude reminded me of a stereotyped chinese drawing i’ve seen in old YouTube videos in 2012

  37. Colonel Banana on December 11, 2021 at 9:58 am
