Oratosquilla fabricii is a species of mantis shrimp found in the Indo-Pacific.

[2] Like other members of its order it has a powerful spear, which it uses to hunt invertebrates and small fish.

It grows to a length of 175 millimetres (6.9 in), and lives at depths of 0–135 metres (0–443 ft).

Males produce sperm ducts rather than spermatophores; females can brood a maximum of 50,000 eggs.

Life cycle: Eggs hatch to a planktonic zoea which lasts for 3 months.
