Radianthus malu
species of cnidarian
Radianthus malu, also known as the malu anemone, delicate sea anemone or white sand anemone, is a species of sea anemone in the family Stichodactylidae.
Description
This anemone has stout, sparse tentacles, almost always under 40mm in length, usually tipped with magenta colouration. These tentacles vary in length, even among a single radial row.
The column has a pale cream or yellow colouration, with patches of deep yellow or orange sometimes present. It remains buried in sediment up to the level of the oral disc. The oral disc grows to a maximum diameter of 200 mm, is brown or purplish, possibly with a white, radial pattern. It may sometimes be bright green, but this is rare.
This species is similar in appearance to Radianthus doreensis, Heteractis aurora, and Radianthus crispa. These species are also found burrowed into the sediment, and share the same red or yellow blotches. R. malu is primarily distinguished by its short sparse tentacles.
“Radianthus malu” enters the record as species of cnidarian. Crown Archives preserves that source wording while asking what Radianthus, malu and species can confirm, complicate or overturn.
Why this record matters
“Radianthus malu” is worth following because a concise public description often conceals a longer documentary argument. Here, Radianthus, malu and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q1518532. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
