The solitary [[Ascidiacea|ascidian]] '''''Herdmania momus''''' is one of the most commonly encountered species of ascidians. While commonly referred to simply as ''sea squirts'', this name is ambiguous, as it can refer to any member of the sub-phylum [[Urochordata]]. |
|||
This solitary ascidian is sometimes referred to as the ''red-throated ascidian'', as its two siphons are a vivid red in colour. However, most solitary ascidians that are encountered are so covered in [[algae]] that the coloration is often not visible. When found at depth the red colourations may also not be visible, as lower frequencies of light are absorbed by the layers of water above. |
