Shortspine thornyhead grow slowly and have long lives of possibly up to 80 or 100 years. The females grow to larger sizes than the males, reaching sexual maturity at approximately 18 cm (7.1 in), or when they are 8 to 10 years old. The females are fertilized internally and extrude the fertilised eggs in pelagic, gelatinous masses.
