Community composition, richness, and density of endobionts from two sponge species in Crete, Greece, June 2021

These data was collected as part of a study titled "The “Single Hotel” hypothesis – Does sponge abundance affect endobionts’ diversity?" that was conducted in the island of Crete, Greece in June 2021. It includes collection of 30 sponge specimens of the common species (Agelas oroides and Sarcotragus foetidus) via SCUBA diving, their dissection and removal and identification of all endobionts living withing them (macroinvertebrates). The diversity of endobionts was then calculated and correlated with sponge properites (such as volume), and the sponges area and site of collection.
