Feed on crustaceans mainly amphipods (Ref. 3167). Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). About 10-56 eggs are laid per individual annually (Ref. 41305, 41314).
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Breeds throughout the year, but ripe females observed mainly in spring and autumn (Ref. 3167). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
