This rabbit is medium-sized, measuring 36–48 cm (14–19 in) in total length, including a small tail that averages 5.3 cm (2.1 in).

Example crosses between pool frog (Pelophylax lessonae), marsh frog (P. ridibundus) and their hybrid – edible frog (P. kl. esculentus). On the left, primary hybridisation generating a hybrid, while the middle is the most widespread type of hybridogenesis. [60] [61] Hybridogenesis is a mode of reproduction of hybrids.
The American Rabbit Breed Association and British Rabbit Council have more than 50 breeds on its books, and more than 500 varieties. Like other species, rabbits come in myriad shapes, sizes, and ...
