Macropodid marsupial have short five digit forelimbs and large four digit hindlimbs specially adapted for hopping. The hindlimb digits differ from mammals by a missing digit 1, fused digits 2 and 3 and an elongated digit 4.

- short pregnancy period (tammar wallaby 26.5 days)
- pregnancy can be maternally delayed (diapause) at blastocyst stage
- born in altricial (underdeveloped) state
- development continues attached to a teat in the pouch
- during pouch period growth controlled by milk composition changes
- immune system, thyroid and thermoregulation develops after birth
The tammar wallaby karyotype (2 n = 16) consists of 7 autosomes and the two sex chromosomes.
