Clytiagracilis is a very small stolonial species of hydroid. It was found growing at the
base of a Cystoseira sp. It has circumglobal distribution.
The photographic material taken at the time is unfortunately not of the expected quality.
However the specimen listed here is described in more detail (p. 189/190) in the following
paper published (2013) by Soto Àngel and Peña Cantero.
