Plakortis dariae

Plakortis dariae is a species of sea sponge in the order Homosclerophorida, first found in vertical walls of reef caves at depths of about 23 to 28 m in the Caribbean Sea. This species has diods of two different categories: it possesses large ones (measuring 67–112μm long) and small, rare, irregular, curved ones, which are often deformed with one of its ends being blunt (measuring 30–59μm long); triods are rare and regular (actines measuring 20–44μm long).
