Placentophagy: eating placenta; Trophallaxis: eating food regurgitated by another animal; Zoopharmacognosy: self-medication by eating plants, soils, and insects to treat and prevent ...
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...
The mountain chicken frog, so-called as it tastes of chicken, is now endangered, in part due to human consumption, and was a major food choice of the Dominicans. [220] Raccoon, opossum, partridges, prairie chicken, and frogs were among the fare Mark Twain recorded as part of American cuisine. [221]
