Tango Stripe Spined Loach

Appearance

Tango Stripe Spined Loach (Tangosujishimadojo, Tango Stripe Spined Loach) is a type of Shimadojo that is endemic to the Tango Peninsula in Kyoto Prefecture. Distribution A river in the Tango Peninsula in Kyoto Prefecture, Honshu. Form The number of stripes for each building is dorsal fin II+7, rump II+5, breast register I+7 ~8, pelvic fin i+6, caudal fin 8+8. Dorsal markings L1 are a row of 11 to 16 square to oval markings. Body side markings L2 to L4 vary greatly among individuals, with L2 having jagged vertical stripes or a row of semicircular markings, L3 having a clear vertical stripe pattern or a thin row of dots, and L4 having a thin mesh-like vertical stripe pattern or a thin row of dots.

Has 3 pairs of mustaches, the length of the second mustache is approximately the same length as the diameter of the eye. Body length is 65-85mm. Ecology They live in the middle and lower reaches of rivers.

Range and habitat

In its habitat, it is often found in sympatric terms with the giant staghorn. Research It was reported by Makoto Takeno et al. In 2010, and was originally called the Sujishima Madonna tetraploid population Tango type. An unidentified population has been confirmed from Lake Mikata in Fukui Prefecture, and it has been reported that the karyotype is similar to the Ogatasujishimadojo, but it is thought to be this species. The characteristics of the mitochondrial DNA base sequence are that it is closely related to Ogatasujishimadojo type A, that is distributed in Lake Biwa, and Yamatoshimadojou type A, that is distributed in Yamaguchi Prefecture.

GBIF currently lists 29 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

The body side marking L5 of females and non-breeding males consists of 11 to 17 circular to oval markings. During the breeding season, the male body marking L4 almost disappears, and L3 and L5 change into distinct longitudinal stripes.

The details of its life history are unknown, but the breeding season is thought to be from May to July, based on changes in the markings on the male's body. It is thought that they move to coastal vegetation areas to spawn, but much remains unknown.

In crisis

Use It is not used commercially because its population is extremely small. As a result, their population is extremely small, and even small-scale environmental changes are highly likely to cause them to go extinct, so they are listed as critically endangered.
