Biology

Very little is known about the biology of this species (3), but there are certain characteristics known to be typical of stingarees (Urolophidae) which the coastal stingaree is likely to possess. This family of rays only has one litter a year, sometimes one every two years, and usually gives birth to between two and four live young per litter. Since so few young are produced, it is important that they survive. Thus, extended nurturing inside the mother's body produces large young able to feed and fend for themselves, with no reported evidence of post-birth parental investment. Some stingaree species have a gestation period of around three months, which usually occurs at some point across spring, summer and autumn. Many stingarees feed on bottom-dwelling fishes, worms, shrimp and other small organisms in the substrate around them, with some species able to eat hard-shelled mollusks and crustaceans (4).
