The scapulae are large. These are considered a remnant of an ancestral defence mechanism. Three weeks later, the female lays a grape sized egg directly into her pouch, which has developed into a depression in the ventral midline bounded by muscular ridges. Adelaide Zoo has bred echidnas on a regular basis, an unusual achievement, and its diet is presented in Table 5. PVC feeding tubes or artificial termite mounds with smooth-edged holes in the base can be used to cover and protect food bowls. There are cervical ribs, cranially projecting scapulae, an unfused acetabulum with a central foramen, outward-rotated hind limbs that result in a backward-facing pestransposition of the tibia and fibula, epipubic bones forward of the pubis and a short flattened femur.

The beak electro-receptors can detect very small electrical impulses emitted by muscular contractions in prey Proske Determining the sex of short-beaked echidnas can be difficult as the sex organs and associated structures are internal and the female pouch is only present when in breeding condition.
Echidnas show evidence of a seasonal breeding pattern. Mackenzie describes the glans as being divided into four bulbous portions by three dorso-ventral grooves. The external ear canal is well-disguised by hair and opens as a vertical slit protected by a ridge of muscle and cartilage Fig.
This is accomplished by the enormous SC muscle panniculus carnosuswhich covers the sides and dorsum.

Different zoos and fauna parks have used different diets with variable success regarding breeding and obesity Jackson Rubber floor covering may be worked loose and the echidna may get under it.
In exhibit design and construction, every effort should be made to respect this most fascinating and beguiling of creatures and provide a captive environment with a rich array of possible activities based on natural behaviours. The water requirement of echidnas has been studied.
The penis is securely retracted into the preputial sac inside the cloaca when not in use. Echidnas have no teeth—food items are secured through the use of an elongated tongue constantly moistened with sticky saliva.

Low-fat diet a. Hibernation more correctly relates to seasonal endurance with minimal periods of awakening, a period of metabolic preparation e. Monotremes possess unique bones in their pectoral girdles: the epicoracoids and the interclavicle, both structural adaptations for digging.
Sperm production is seasonal and correlates well with testicular size; production peaks in August and is lowest in late spring Johnston et al. They demonstrated an inferior immune response in the echidna relative to the rabbit based upon antibody production and secondary response to antigen administration.

The perimeter walls of outdoor enclosures should be solid, smooth and vertical to at least 50 cm to prevent escape.
Although authors seem reluctant to classify the female reproductive pattern, it is likely to be seasonally polyoestrous. Faeces produced with this diet are tube-like, like those of wild echidnas. Prior to egg-laying, the female excavates a burrow which consists of a short tunnel terminating in a nesting chamber. The small intestinal mucosa has high trehalase activity corresponding to the high trehalose content of termites and ants.
The diets offered are presented in Table 5.

|Passive integrated transponders PIT tags or microchips are most commonly used to permanently mark individual echidnas.
The name echidna derives from Ekhidna, a Greek goddess who was half woman and half reptile. Nipples are absent and milk is expressed directly onto the skin of the anterior pouch via specialised hair follicles concentrated into two regions patches or areolae of the anterior pouch skin. With its strong fore limbs the echidna breaks open termite mounds, rotten logs and ant nests to probe for food. The bladder also joins directly to the urogenital sinus opposite and dorsal to the entry of the ureters.
