We believe that this was probably erroneously. In his pioneering works representing the only previous cytogenetic examination of the family Helodermatidae, Matthey reported the karyotype as 2nâ€Š=â€Š38 and suggested a different chromosomal morphology for this species. 2nâ€Š=â€Š36 is the widely distributed chromosomal number among squamates. Moreover, we found that the karyotype of the Gila monster consists of 2nâ€Š=â€Š36 chromosomes (14 larger metacentric chromosomes and 22 acrocentric microchromosomes). If the sex chromosomes of helodermatids and varanids are homologous, female heterogamety may be ancestral for the whole Anguimorpha group. The sex chromosomes are morphologically similar to the ZZ/ZW sex chromosomes of monitor lizards (Varanidae).

We uncovered homomorphic ZZ/ZW sex chromosomes in the Gila monster ( Heloderma suspectum) with a highly heterochromatic W chromosome. In this respect, one of the most understudied groups is the family Helodermatidae (Anguimorpha) encompassing the only two venomous species of lizards which are potentially lethal to human beings. However, we still have only a limited knowledge of sex determination in certain important lineages of squamates. They can therefore serve as an important model for studies of evolutionary transitions among particular sex determination systems.

Sex Chromosomes and Karyotype of the (Nearly) Mythical Creature, the Gila Monster, Heloderma suspectum (Squamata: Helodermatidae) This increased surface activity can lead to greater food acquisition for supplemental Gila monsters because tail volume (an index of caudal lipid stores) was significantly greater in supplemented lizards compared with controls in one of the two study years.

During seasonal drought, water-supplemented lizards were surface active a significantly greater proportion of time than were controls. Water-supplemented lizards had lower plasma osmolality (i.e., were more hydrated) and maintained urinary bladder water reserves better during seasonal drought than did control lizards. We used a combination of the natural climate pattern of the Sonoran Desert and periodic water supplementation to determine the extent to which water intake influenced both the behavioral ecology and the physiological ecology of a long-lived desert lizard, the Gila monster ( Heloderma suspectum) (Cope 1869). However, the underlying reason for such seasonality can be hard to discern because the rainy season is often associated with shifts in temperature as well as water and food availability. In desert species, seasonal peaks in animal activity often correspond with times of higher rainfall. Water supplementation affects the behavioral and physiological ecology of Gila monsters ( Heloderma suspectum) in the Sonoran Desert. In this paper we report the 28th credible record of a Gila Monster in California. In May 2009 another sighting in California was documented by Ruppert (2010a, b) who photographed a specimen in the Providence Mountains, an area known for previous Gila Monster sightings (Lovich and Beaman 2007). In their review of Gila Monster records for California, Lovich and Beaman (2007) documented only 26 credible sightings during a period of 153 years. A previously unreported locality record for the Gila monster ( Heloderma suspectum)Īlthough the Gila Monster ( Heloderma suspectum) is widely distributed throughout the Sonoran and portions of the Mojave Deserts of the southwestern United States and northwestern Mexico, details of its distribution in California are imperfectly known, due to the apparent rarity of the species in that state.
