Sea Spiders Can Regenerate Their Butts

PJM: German researchers have published fascinating findings from their recent experimental work in evolution.

Via LiveScience:

In a series of experiments, scientists discovered that juveniles from the sea spider species Pycnogonum litorale were able to fully regenerate a number of amputated body parts from their lower body, including hind limbs, parts of their guts, reproductive organs and even their anuses. 

Sea spiders, which belong to the class Pycnogonida, are a group of around 1,300 marine arthropods with eight legs. While they look similar to terrestrial spiders they are only very distantly related to them. Other arthropods, such as spiders, centipedes and crabs, can also regenerate body parts, enabling them to escape predators that have taken a bite out of them.

  1. …I once read an exhaustive study about a certain species of desert toad that started with “this toad is observed to urinate before jumping when startled. Water is a precious resource in the desert, so why void the bladder?”, and ending up after 40 odd pages detailing all-expense paid research grant trips to exotic locales all over the world by positing ” the weight the toad relieves its bladder of allows it to jump further to escape danger.

    Three years they spent researching that.

    …not found anywhere in this lengthy screed was anything explaining who asked this question, why we needed to know the answer, how we can be SO sure that IS the answer (maybe its just easy to scare the literal piss out of a toad?) and what we’re supposed to DO with that answer even if it IS true.

    All government…taxpayer…funded.

    This was quite some time ago, so I’m sure they’ve done more and stupider since then.

    …and we wonder where all those trillions go that aren’t sent to U̶k̶r̶a̶i̶n̶e̶ Democrats…

  2. These are German Medical tests?
    They sit around and cut things off things?
    And watch?
    And take notes?
    To see what and how much can be cut off each test subject?
    Is this what it is all about?
    The Yellow Submarine Base in the Ukrainian Navy?

    Interesting.

  3. Yeah, more German ‘scientists’ experimenting on living things. Where have we heard that before? It didn’t end well.

    Did they have a shortage of beagle puppies or something?
