The species of rattlesnakes that inhabit the islands Gulf California in México represent a group vertebrates are endangered (García-Padilla et al., 2018). main pressures they face invasive and illegal capture for commercialization (Mellinck, 1995). Presently, aspects natural history conservation status many populations various still remain virtually unknown to science. During May-June 2009, we visited Isla El Muerto where there exists an insular population rattlesnake Crotalus pyrrhus (Meik 2015). taxonomic this has been discussed, but almost nothing published about its ecology history. Here, present new data concerning distribution, relative abundance, species. We established might be less abundant than previous authors mentioned; estimated abundance obtained is 0.22 snakes/hour. Also, identified provided by Mexican (NOM-059 SEMARNAT, 2019) international (IUCN) systems needs revised modified allocate higher level protection. believe information can used as basis promoting achieving effective protection C. habitat perpetuity
