Species of fish
The thread pipefish (Kyonemichthys rumengani ), also known by its Japanese standard name Hari-youji ,[ 3] is a species of pipefish native to the Pacific Ocean around Indonesia , where it is found at depths from 15 to 20 m (49 to 66 ft).[ 2] This species grows to a length of 2.68 cm (1.06 in), and is the only known member of its genus .
Taxonomy and systematics
Kyonemichthys rumengani was originally described in 2007 based on an adult female specimen collected in the Lembeh Strait , Sulawesi .[ 4] Originally it was thought to be related to the pygmy pipehorse genera Acentronura & Idiotropiscis based on morphological similarities, but mitochondrial genetic analyses have found that Kyonemichthys is instead a sister taxon to Urocampus , forming a clade which excludes the phylogenetically distant Acentronura , Idiotropiscis , and Siokunichthys .[ 3]
Distribution and habitat
First discovered in Indonesia , Kyonemichthys rumengani appears to be widespread throughout the Indo-Pacific . It has been recorded in the Red Sea off Egypt , the Ryukyu Islands , the Philippines , Fiji , the Mariana Islands & Papua New Guinea .[ 3] [ 5] It is found in mixed habitats on shallow coastal reefs & has been observed orienting itself by using bryozoans , hydroids & debris as holdfasts.[ 3]
