80,000 octopus paralarvae released along coastal transition. High survival in rocky reefs; crabs evade in sediment lagoons.

Substrate Paradox Finding

The Lagoon Vulnerability: While octopuses (*Octopus vulgaris*) exert severe 82% predation in structured rocky crevices, blue crabs (*Callinectes sapidus*) in sandy lagoons burrow 5–10 cm into soft sediment to evade detection, while fragile paralarvae face elevated mortality in murky shallow waters.
