The thylacine resembled a large, short-haired dog with a stiff tail which smoothly extended from the body in a way similar to that of a kangaroo. [31] The mature thylacine measured about 60 cm (24 in) in shoulder height and 1–1.3 m (3.3–4.3 ft) in body length, excluding the tail which measured around 50 to 65 cm (20 to 26 in). [33]
The only species to survive into modern times was the thylacine (Thylacinus cynocephalus), which became extinct in 1936. The consensus of authors prior to 1982 was that the thylacinid family were related to the Borhyaenidae , a group of South American predators, also extinct, that exhibited many similar characteristics of dentition.
The last known Tasmanian tiger was in the Beaumaris Zoo in Tasmania, eventually dying in 1936. The earliest known member of the genus, Thylacinus macknessi appeared during the Early Miocene, around 16 million years ago, and was smaller than the modern thylacine, with a body mass of about 6.7–9.0 kilograms (14.8–19.8 lb).
The breeding pond is a very noisy place, and females must distinguish a male's calls from the other noise. How they recognize the sound pattern of the male they are pursuing from the surrounding noise is similar to how intelligent hearing aids help people hear certain sounds and cancel out others.
A litter is the live birth of multiple offspring at one time in animals from the same mother and usually from one set of parents, particularly from three to eight offspring. The word is most often used for the offspring of mammals , but can be used for any animal that gives birth to multiple young.

Very precocial birds can be ready to leave the nest in a short period of time following hatching (e.g. 24 hours). Many precocial chicks are not independent in thermoregulation (the ability to regulate their body temperatures), and they depend on the attending parent(s) to brood them with body heat for a short time. Precocial birds find their ...
Gestation, called pregnancy in humans, is the period of time during which the fetus develops, dividing via mitosis inside the female. During this time, the fetus receives all of its nutrition and oxygenated blood from the female, filtered through the placenta, which is attached to the fetus' abdomen via an umbilical cord.
