The shortnose spurdog (Squalus megalops) also known as the piked spurdog is a small shark located primarily off the coast of Southern Australia and South Africa. The shortnose spurdog's size is dependent on the sex of the animal. The female shortnose spurdog is consistently larger than the male shortnose spurdog and will typically measure out to about 56.41 cm (1.85 ft) while the male shortnose spurdog will typically only measure out to about 44.36 cm in length (1.46 ft) which means the female shortnose spurdog is over 10 cm longer than the male shortnose spurdog. Some females can even measure up to 78 cm which is over 2.5 feet long. The life span of spurdog's can be quite long with females typically living longer than males. The average life span of a female shortnose spurdog is 0–29 years old while the male life span is 0–26 though it is estimated that a female can live up to 46 years while a male can only live up to 33.
