Amphimedon texotli is a species of marine demosponge in the genus Amphimedon, family Niphatidae. It is known from the tropical eastern Pacific, including coastal regions of Mexico, where it inhabits shallow rocky reefs and subtidal environments. This species typically forms encrusting to low, irregular masses that adhere closely to hard substrates such as rock or coral. Like other members of Amphimedon, A. texotli is a filter feeder, pumping seawater through its canal system to remove bacteria, microscopic algae, and organic particles. Its internal skeleton consists of spongin fibres reinforced with siliceous spicules, providing both flexibility and structural support.
