🥚 Reproduction

Size at Maturity
77cm TL

Some experts believe that some form of copulation happens during breeding of this species. The female turns on her side to expose her abdomen to the male who then swims against her in a forceful movement. Aftewards, the female takes a rest and deposits her eggs in the sand. This whole activity is presumably repeated one more time . Other experts believe otherwise, that only a simple and simultaneous discharge of gametes happens during breeding .
