A boat is said to be turtling or to turn turtle when it is fully inverted. [1] [2] The name stems from the appearance of the upside-down boat, similar to the carapace (top shell) of a sea turtle. [3] [A] [B] The term can be applied to any vessel; turning turtle is less frequent but more dangerous on ships than on smaller boats.
When I came closer I saw this beautiful turtle turned upside down with a look of hopelessness and exhaustion in her eyes, her body knotted and entangled in a fishing net," she captioned the reel ...
Damage to or inordinate motion of the protruding egg yolk – enough to allow air into the turtle's body – results in death. This is the main reason for marking the top of turtle eggs if their relocation is required for any reason. An egg turned upside down will eventually terminate the embryo's growth by the sac smothering the embryo.
The Argentine snake-necked turtle is an example of a flat turtle, which relies on its long neck and legs to turn over when placed upside down. The balancing properties of gömböcs are associated with the "righting response" — the ability to turn back when placed upside down — of shelled animals such as tortoises and beetles. These ...

If the static stability curve never crosses the x-axis, the boat is not stable upside-down. This is not sufficient to build a boat with good stability at sea, as it neglects the effects of wind, waves, and human occupants, but it is a simple, powerful way to analyze the stability of a vessel. [11] See also primary stability and secondary stability.
Just as a bottom-weighted (nonhomogeneous weight distribution) sphere would always return to the same upright position, they found it was possible to construct a shape that behaves the same way. After that, they noted the similarity to the Indian star tortoise and subsequently tested 30 turtles by turning them upside down.
