  • They move very quickly. They tend to quickly kill themselves by bumping their heads into aquarium walls.

    If they don’t die from bleeding, trauma, or infection, or stress, they tend to die pretty quickly from asphyxiation. As whenever they bump into the wall, they get suprised, and spray ink. In an aquarium, the ink stagnates and blocks them from breathing properly.


  • That’s probably an octopus or maybe a cuttlefish but not a squid.

    Squid can’t be kept captive they die within a day or two. And only octopus have the flexibility to change into “a rock” and can be kept as pets.

    But very slight chance its a cuttlefish because I can’t see very well if its completely changed shape or not in pic 2.

    From an AI, so take with some salt:

    Yes, gravity is believed to travel at the speed of light.

    According to Einstein’s theory of general relativity, the effects of gravity propagate through spacetime at the speed of light. This means that if a massive object were to suddenly change its position, the gravitational effects would not be felt instantaneously by objects around it, but would instead spread outward at the speed of light.

    This is in contrast to the classical Newtonian view of gravity, which treated it as an instantaneous force. Einstein’s theory showed that gravity, like other forms of electromagnetic radiation, obeys the speed limit set by the speed of light.

    Experimental evidence, such as observations of binary pulsars, has confirmed that gravity does indeed propagate at the speed of light, as predicted by general relativity. This is a crucial aspect of our modern understanding of the nature of gravity and its relationship to the fabric of spacetime.​​​​​​​​​​​​​​​​
