Similar to mammals, these ringed caecilians make a nutrient-rich milk-like fluid to feed their mewling hatchlings up to six times a day.

      The authors of the paper uploaded 6 videos in the supporting info. It looks like mucus to me, but it is difficult to see. I cropped one video in which you can see strings of the “milk”: https://i.imgur.com/9RvVSgz.mp4

      You can get the zip file with the 6 videos here: https://www.science.org/doi/suppl/10.1126/science.adi5379/suppl_file/science.adi5379_movies_s1_to_s6.zip

      I also found a video of a frog feeding its tadpoles through the skin: https://static-content.springer.com/esm/art%3A10.1007%2Fs10682-023-10259-z/MediaObjects/10682_2023_10259_MOESM2_ESM.mp4

      The frog video comes from this paper: https://link.springer.com/article/10.1007/s10682-023-10259-z

          You are welcome!

          I also have a snippet from one of the videos that shows in more detail how the fluid is excreted. I will hide it under a spoiler tag to make sure people are warned of the content before clicking the link, because I think these images might be uncomfortable to watch for some people.

          spoiler

          Here’s the video in which you can see the mom excreting a thick fluid through her cloaca: https://i.imgur.com/sB22z5G.mp4

          This snippet comes from the video 5 from the supporting information.

About

Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence. However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

Over generations, all of the species that are currently alive today have evolved unique traits that make them distinct from other species. These differences are what scientists use to tell one species from another. Organisms that have evolved to be so different from one another that they can no longer reproduce with each other are considered different species. All organisms that can reproduce with each other fall into one species. Read more…

Rules

  1. Don’t throw mud. Be kind and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
