[3] Although this is the typical geographical distribution, the species has also been found off the Mediterranean coast of Israel and in the Gulf of Gabčs in southern Tunisia.

[4] D. chrysonota is easily distinguishable from other stingray species by the appearance of faint blue splotches and lines on its light-brown triangular disc body.

[5] The size of male and female blue stingray show no distinction from birth until adolescence (approximately 4 years old) in which sexual differences become noticeable.

Seasonal fluctuations in temperature and light are likely significant controlling factors in growth rate and band formation.

Crustaceans and molluscs are the most common prey among other closely related species of stingray.

The medium and large size classes of D. chrysonota are important predators in the nearshore sandy beach ecosystem in the surf zone of southern African waters, however the majority of prey for the very large class size is found nearshore and offshore, mostly consisting of Callianassa spp.

[5] Sexual maturity of males is reached at a smaller size and at an earlier age than that of females.
