The three most adorable new reef species this year
Three new species of pygmy seahorses are described in Zootaxa.
Hippocampus pontohi has been observed on the coralline algae Halimeda, as well as on the hydroid Aglaephenia cupressina (Müller and Severns, pers. comm.).
In Indonesia, [Hippocampus severnsi] has been recorded in association with a yellow coloured bryozoan, Catenicella sp., on different kinds of hydrozoans including Lytocarpus phoenicea, Antennellopsis integerrima and Halicordyle disticha (Müller, pers. comm.) as well as in sheltered spots on a reef wall in association with Halimeda (Brett, pers. comm.). It is also recorded from fissures on current–swept walls where it will tend to occur on the side of the fissure that faces away from the current, but in all cases where there is some upward current (Müller, pers. comm.) and has been seen swimming over a fungiid coral (Hardt, pers. comm.). In Papua New Guinea it has been observed in a healthy reef passage with a regular current of up to two knots on a gorgonian of the genus Muricella at 12 m depth (Halstead, pers. comm.) and in Fiji it was found on gorgonian species, possibly Menella sp.?
Hippocampus satomiae congregates at night in groups of 3–5 individuals on small seafans. During the day H. satomiae are difficult to find, even in areas where they are known to occur.
