Description

Loimia medusa has long bluish white feeding tentacles that give the appearance of spaghetti noodles under any kind of rubble or rocks. [3] Under those rocks, it has a body that is surrounded by a tube consisting of bits of shell and gravel, [4] creating a tube that has a tough membranous lining with segments. The body can grow to be about 12 in (300 mm) long, while the tentacles can grow to twice that length. [5]

Distribution and habitat

Loimia medusa prefers tropical oceans, such as the Indo-Pacific and the Western Central Atlantic, [6] including reefs off of the Hawaiian Islands. [7]

Its habitat includes spaces such as tidepools, brackish waters, and bays that consist of rubble. [6] They can also be found in sand and coral reefs in the deeper waters across the Hawaiian islands. [8]

Cultural significance

In Hawai'i, Loimia medusa is known as the Kauna'oa. During the Old Hawai'i times, this invertebrate was used for medicinal purposes. [4]
