“…18,31 The ultrasonographic appearance of coelomic organs has been reported in amphibian. 25,27 However, few studies described axolotl ultrasonography. 32 A study on axolotls' echocardiography is available with detailed description of heart anatomy.…”

“…25,26 By taking ethical considerations into account, ultrasounds allows organs exploration and diseases monitoring without pain in amphibians. 25,[27][28][29] This ability is vital for both wild populations and pet axolotls, as early detection of illnesses can facilitate timely treatment. Moreover, ultrasonography can assist in studying reproductive organs and processes, aiding both conservation efforts for wild populations and breeding programs for pet amphibians.…”

Axolotls (Ambystoma mexicanum) are widely studied for human medical research. While critically endangered in wildlife, they have also become popular as household pets. Although they have been kept in captivity for over a century, coelomic organs description of their anatomy remains limited, and this species presents significant variations compared to other amphibians. Ultrasound is a non-invasive, painless medical imaging technique, well-suited for investigating internal organs or other structures. This study describes ultrasound appearance of the axolotl coelomic cavity. Identification, localization and parenchyma description of major organs are reported on 28 neotenic axolotls by using frequencies between 7 to 15 MHz. Results were confirmed by comparing ultrasound and necropsy on one male and one female. The heart, lung surface, liver and reproductive tracts were observed. Measurements with confidence intervals were calculated for spleen, kidneys, testicles, gastric wall, gallbladder, and pylorus. Hyperechoic millimetric particles in gallbladder or ascites were occasionally detected. Pancreas and bladder could not be observed. The outcomes of this research include the production of images combined in an atlas. The experiment showed a repeatable and easily accessible protocol for anatomy-morphological assessment in axolotl medicine and is the necessary step before identification of lesions.

Axolotls (Ambystoma mexicanum) are extensively studied for their relevance in human medical research. Despite being critically endangered in the wild, they have gained popularity as household pets. Although they have been kept in captivity for over a century, detailed descriptions of their coelomic organ anatomy remain limited. Also, this species exhibits significant variations compared to other amphibians. Ultrasound is a non-invasive and painless medical imaging technique, ideally suited for investigating internal organs or structures. This study focused on describing the ultrasound appearance of the axolotl coelomic cavity. It details the identification, localization and parenchymal description of major organs in 28 neotenic axolotls using ultrasound frequencies ranging from 7 to 15 MHz. The accuracy of the results was validated by comparing ultrasound findings with necropsy results from one male and one female axolotl. The heart, lung surface, liver and reproductive tracts were visualized. Measurements, along with confidence intervals, were calculated for the spleen, kidneys, testicles, gastric wall, gallbladder, and pylorus. Occasional detection of hyperechoic millimetric particles in the gallbladder or ascites was noted. However, visualization of the pancreas and bladder was not possible. This research outcomes involve the development of a comprehensive atlas comprising images obtained throughout the study. Additionally, the experiment established a reproducible and readily accessible protocol for conducting anatomy-morphological assessments in axolotl medicine. This protocol stands as a crucial preliminary stage before advancing to lesion identification.
