Clathrina antofagastensis is a species of calcareous sponge from Chile. The species is named after Antofagasta, Chile, where the holotype was discovered.

Description

Specimens are massive, the largest is 20 x 30 x 10 mm. Cormus is composed of large, irregular and tightly anastomosed tubes. Water-collecting tubes are not present. The skeleton is composed of two categories of triactines without organisation:

Triactine I: regular (equiangular and equiradiate); actines are slightly conical to conical, straight and blunt at the tip.
Triactine II: regular (equiangular and equiradiate) in most cases, although sagittal spicules are also present. These spicules are very small. Actines are conical, straight and blunt at the tip.^[1]
