Cambarellus zacapuensis is a small crustacean endemic to the Angulo River basin, observed mainly in Zacapu Lagoon.

C. zacapuensis has a pigmented body, well-developed eyes, and a rostrum with marginal spines.

[1] Cambarellus zacapuensis is found mainly in Zacapu Lagoon and in some of its drains such as the Angulo River.

It is usually found at a shallow depth, between submerged roots and in the aquatic substrate.

The exploitation of the water resources of their habitat by human action also represents a threat to the small crustacean, which is why it could be considered critically endangered under IUCN criteria.
