“She produced a foetus that was 99.9% genetically identical to herself.” “The egg was laid by an 18-year-old female American crocodile in Parque Reptilania in January 2018. The foetus inside was fully formed but stillborn and so did not hatch.” “The crocodile who laid the egg was obtained when she was two years old and was kept apart from other crocodiles for its entire life.” “There was a big increase in reports of parthenogenesis when people started keeping pet snakes. But your average reptile keeper doesn’t keep a crocodile.” “The fact that the mechanism of parthenogenesis is the same in so many different species suggests that it is a very ancient trait that has been inherited throughout the ages. So this supports the idea that dinosaurs could also reproduce this way.”—”Crocodile found to have made herself pregnant. The first case of a crocodile who made herself pregnant has been identified at a zoo in Costa Rica.”
OMG. Let her have friends, ffs.
See “Discovery of facultative parthenogenesis in a new world crocodile“—”Over the past two decades, there has been an astounding growth in the documentation of vertebrate facultative parthenogenesis (FP). This unusual reproductive mode has been documented in birds, non-avian reptiles—specifically lizards and snakes—and elasmobranch fishes. Part of this growth among vertebrate taxa is attributable to awareness of the phenomenon itself and advances in molecular genetics/genomics and bioinformatics, and as such our understanding has developed considerably. Nonetheless, questions remain as to its occurrence outside of these vertebrate lineages, most notably in Chelonia (turtles) and Crocodylia (crocodiles, alligators and gharials). The latter group is particularly interesting because unlike all previously documented cases of FP in vertebrates, crocodilians lack sex chromosomes and sex determination is controlled by temperature. Here, using whole-genome sequencing data, we provide, to our knowledge, the first evidence of FP in a crocodilian, the American crocodile, Crocodylus acutus. The data support terminal fusion automixis as the reproductive mechanism; a finding which suggests a common evolutionary origin of FP across reptiles, crocodilians and birds. With FP now documented in the two main branches of extant archosaurs, this discovery offers tantalizing insights into the possible reproductive capabilities of the extinct archosaurian relatives of crocodilians and birds, notably members of Pterosauria and Dinosauria.”
