There are currently 163 species of Geodia Lamarck, 1815 described worldwide, many of which are found in deep waters, but none of which have been recorded from the Southwest Indian Ridge (SWIR). Spicule morphology and barcodes (Folmer COI, 28S (C2D2), partial 18S) suggest that a specimen of Geodia collected on the SWIR at a depth of 2236 m is closely comparable to Geodia barretti Bowerbank, 1858. Geodia barretti is the most studied and thus well-known deep-sea Geodia species, due to its wide North Atlantic distribution and key role in boreal sponge grounds. This unexpected and markedly disjunct record would extend the distribution range of this species considerably, consequently challenging our knowledge about interoceanic deep-sea sponges.
目前已描述了全世界有 163 种 Geodia Lamarck,1815 种,其中许多种生活在深海中,但在西南印度洋脊(SWIR)都没有发现。骨针形态和条形码(Folmer COI、28S(C2D2)、部分 18S)表明,在 SWIR 深度 2236 米处采集的一个 Geodia 标本与 Bowerbank,1858 年描述的 Geodia barretti 非常相似。Geodia barretti 是研究最多、因此也是最知名的深海 Geodia 物种,因为它在北大西洋的分布广泛,并且在北方海绵场中起着关键作用。这一意外且明显的分散记录将大大扩展该物种的分布范围,从而挑战我们对跨洋深海海绵的认识。
