The scyphozoans are considered as one of the potential bio-indicator species of the coastal marine ecosystems. The genus Crambionella, belonging to the family Catostylidae, represents a total of four species globally. The jellyfish Crambionella orsini (Vanhöffen in Bibliotheca Zool 1:1–52, 1888) is mostly distributed to the western Indian Ocean. In this present study, this species is reported from Lakshadweep for the first time though it was reported from other parts of the Arabian Sea previously. This present paper deals with the morphological characteristics of C. orsini along with its global zoogeographical ranges.

水生动物被认为是沿海海洋生态系统的潜在生物指示物种之一。Crambionella属属于 Catostylidae 科，在全球共有四个物种。水母Crambionella orsini (Vanhöffen in Bibliotheca Zool 1:1–52, 1888) 主要分布于西印度洋。在本研究中，该物种是第一次从 Lakshadweep 报道，尽管之前报道过阿拉伯海其他地区。本论文涉及C. orsini的形态特征及其全球动物地理范围。
