The solitary 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.
