Glass frogs become see-through by hiding their blood

It is indeed a poignant reflection to consider the ethical implications of scientific experimentation on non-human animals, particularly when such research involves the abduction of these creatures from their natural habitats and ultimately results in their death. The pursuit of knowledge and understanding is a crucial aspect of the scientific enterprise, but it is essential that we also consider the ethical implications of our actions and strive to minimize harm to other beings as much as possible. In this case, the researchers may have been motivated by a desire to advance our understanding of the biological processes at work within these animals, but it is important to recognize that this pursuit of knowledge must be balanced against the value and dignity of the beings being studied.

    Humans have been capable of mildly rambly writing for several thousand years longer than ChatGPT has been around.

    I thought the same. Amusingly, the poster’s other comment is written in a much different style, so it looks like our detectors are well-calibrated.

    LOL yeah it cleaned up my response well

  I'd say that all ethics is off the table if any of these scientists enjoys a chicken burger for lunch, like millions of people doing all sorts of jobs.

    It's not fair to ignore ethics. Spousal abuse was legal for a long time. It wasn't until the Declaration on the Elimination of Violence Against Women in 1993 that violence in a marriage would result in consequences. Protecting the weak is important.

How do Glass Frogs' body tissue, skin, and musculature survive an entire sleep cycle without significant blood flow?
- pvaldes 4y ago
  being tiny and using the skin to breathe (so they need to be tiny or flat for allowing a good gas exchange at all levels)

Funny how their eyes are still so distinct, confirming the old scifi idea that the biggest problem with invisibility is being able to see.

> How the animals survive this extreme adaptation is unclear, says study co-author Jesse Delia I see what Jesse did there.

There is a lot missing here. Getting the red blood cells out of the way may be a necessary condition for transparency but it isn't sufficient. I mean, if you drain blood out of a body and replace it with a clear liquid (think embalming fluid), you don't end up with transparency. The tissue has to be fundamentally transparent, but for those pesky RBC's.
