在地中海，两种海绵属Aplysina（A. aerophoba和A.根据其外部形态和生活环境来识别。在对意大利海岸半淹没洞穴中海绵动物群的研究计划中，我们对一种丰富的非常小的黄色海绵进行了采样，这种海绵通常生活在潮汐带，属于Aplysina属。未能通过经典的分类方法（生长形式和骨架排列）和这种海绵生活的特定环境将样品分配给一个物种，我们决定使用COI分析来解决这些微型标本提供的分类问题。分析表明，尽管形态上存在差异，但它们都属于A.航空恐惧症。在过去的详细调查中，在60年的一些研究洞穴中进行的，这个物种没有记录。它的大量存在可能与过去几十年中发生的与全球变暖有关的地中海海绵群落的变化有关。
In the Mediterranean Sea, the two sponges of the genus Aplysina (A. aerophoba and A. cavernicola) are identified on the basis of their external morphology and the environment in which they live. During a research program on the sponge fauna in semi-submerged caves of the Italian coasts, we have sampled an abundant very small yellow sponge, often living in the tidal zone, which were attributed to the genus Aplysina. Failing to assign the samples to a species through classical taxonomic methodologies (growth form and skeleton arrangement) and for the particular environment where this sponge lives, we have decided to use the COI analysis to solve the taxonomic problem offered by these miniaturized specimens. The analysis indicated that, in spite of the morphological differences, they belong to A. aerophoba. During old detailed surveys, conducted in the '60 years in some of the studied caves, this species was not recorded. It is possible that its abundant presence is related to the modifications occurred in the Mediterranean sponge communities occurred in the last decades in relation to global warming.
