Today, according to my 12yo, it’s Aquatic Caecilian or Rubber Eel Awareness Day! Prompted by the question, “What are those other amphibians who aren’t frogs or salamanders again?”

🇸🇨 Seychelles has 8 endemic caecilian species. Seven of them can all be found in Morne Seychellois National Park on Mahé island. These limbless amphibians are highly understudied due to their underground burrowing lifestyle. However, the difficulty makes finding one very rewarding!

💧 Biologists found an amphibian called a caecilian hiding away in a Florida canal in 2019. The species is native to South America, but a recent study by Coleman Sheehy and team show that they're now firmly established in Florida. Paper:

Here's a Nakon Si Thammarat Caecilian (Ichthyophis supachaii), observed in a shallow rivulet near a forest trail in peninsular Thailand, 2023. Caecilians are amphibians, & generally live underground, although there are some completely aquatic species.

The Second Species of Caecilian in China
<p indent="0mm">A new unstriped <italic>Ichthyophis</italic> is found in Yunnan, China, it is distinguished from its unstriped congeners in morphology by a combination of characters including HL (head length), the number of annuli (369–372), vertebrae (114), inner mandibular teeth (36) and premaxillary-maxillary (51). The new species is also distinguished from its closest neighbour congener by a significant genetic divergence which is greater than 5.8% in the mitochondrial <italic>COI</italic> gene and greater than 6.3% in the mitochondrial <italic>cyt-b</italic> gene. As the first unstriped <italic> Ichthyophis</italic> species found in China, it is also the second species of Caecilians (Amphibian: Gymnophiona) found in China.</p> <?Pub Caret 25?>

#caecilian
lovers! There’re 224 species of caecilian (Gymnophiona) as of 31/DEC/2024 according to @AmphibiaWeb Of the 88 new species of amphibians in 2024, just 2 were caecilians. Encouraging naturalists to get out there and dig; new species are waiting for you!
