The spanner crab or more popularly known in Zamboanga city as the Curacha is like a gigantic brilliant-red orange cockroach with pincers and fringed with hair at its sides. The name curacha is so close to the chavacano word cucuracha which literally means cockroach, thus the name.
It may be a weird looking monster-like crustacean but many are longing to dine on these Indo-Australian crabs once they are cooked, minimally either steamed or boiled, because it is best experienced in its natural exotic flavor, so as to preserve its original taste.
You should add sauce toppings made with a combination of gata (coconut milk), ginger, chili and other aromatics to enhance the flavor. But the well-loved special sauce from the Alavar Seafood Restaurant seems to be the most highly recommended in the city.
Contrary to what others are saying, these sea creatures can also be found in other waters aside from just Zamboanga. It just so happens that Zamboanga was the one that made it popular as the iconic must-try native delicacy when you go visit Asia's Latin City.
