Dragmacidon lunaecharta
species of sponge
Dragmacidon lunaecharta, also known as the red ball sponge or red boring sponge, is a species of sea sponge found in the western Atlantic Ocean. It feeds on plankton. These sponges do not attach themselves to rocks or the sea floor but drift in water currents. Its main predators are sea slugs. It has been kept in home aquariums.
Taxonomy
It was first described in 1886 by Stuart Oliver Ridley and Arthur Dendy as Axinella lunaecharta, but in 1887, in their final report, they transferred it to the genus, Pseudaxinella. In 1917, E.F. Hallman revised some genera in the family, Axinellidae, and transferred it to the genus, Dragmacidon.
The public source identifies “Dragmacidon lunaecharta” as species of sponge. This brief keeps that definition visible, then builds a research path around Dragmacidon, lunaecharta and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Dragmacidon lunaecharta”, the useful work is to connect “species of sponge” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 8, 2025. The linked authority identifier is Q2190916. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1886, 1887 and 1917.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
