Synodontis lucipinnis ist ein Angehöriger der Gattung Synodontis, welcher zur Unterfamilie der Fiederbartwelse (Mochokinae) innerhalb der Familie Mochokidae gehört. Die Art wurde 2006 durch Jeremy J. Wright und Lawrence M. Page erstbeschrieben. Das Artepitheton lucipinnis bedeutet „helle“ (lat. lucidus) „Flosse“ (lat. pinnis).[1]

Merkmale

Synodontis lucipinnis wird maximal 15 cm lang, die Standardlänge beträgt 8–10 cm.[2] Der Körper ist dunkelgrau bis hellgrau gefärbt. Auf diesem befinden sich schwarze ovale Flecken. Die Zahl der Flecken ist am Kopf am höchsten. Der erste Strahl der Rückenflosse ist weiß gefärbt, sowie die äußeren Ränder aller anderen Flossen auch.

Flossenformel: Dorsale II/7-8, Anale 0/7-8[3]

Der Körper des Fisches ist unverkürzt und dabei vor der Rückenflosse leicht konvex. Die Haut des Körpers bildet leichte Falten und der Kopf ist abgeflacht und breit. Die Augen befinden sich an den Seiten der Kopfoberseite und das Maul ist unterständig. Die Barteln erstrecken sich in ihrer Länge bis mindestens zur Basis der Brustflossen. An der Basis der Barteln befinden sich Papillen. An den Lateralbarteln befinden sich jeweils vier bis sechs Abzweigungen, welche selbst keine Abzweigungen besitzen. Die Hartstrahlen der Pectorale sind ungefähr von gleicher Länge wie die Hartstrahlen der Dorsalen. Die Fettflosse ist ausgeprägt und langgezogen.[3]

Die Synodontis-Arten des Tanganjikasees sind von den Vertretern aus allen anderen Gewässern dadurch zu unterscheiden, dass sie (mit einer Ausnahme: S. melanostictus) in den Flossen dunkle Keile und Balken besitzen. Alle Tanganjikasee-Arten besitzen zumindest im Jugend- bzw. Halberwachsenen-Stadium viele dunkle Punkte auf beige-braunem oder weiß-grauem bis grauem Grund.

Verbreitung und Ökologie

Syndontis lucipinnis ist im Tanganjikasee endemisch und nur an der Typusfundstelle in Sambia zu finden. Die Art ernährt sich omnivor.[3]

Verhalten und Fortpflanzung

Als semi-adulte Tiere leben Synodontis lucipinnis eher versteckt in Gruppen. S. lucipinnis lebt auch im erwachsenen Alter sozial in Gruppen, wobei die Tiere auch über Beißen kommunizieren.

Synodontis lucipinnis vermehrt sich freilaichend, das heißt die Eier werden frei ins Wasser abgegeben, anders als bei wenigen anderen Synodontis-Arten, welche ihre Eier maulbrütenden Buntbarschen überlassen. Diese Buntbarsche brüten die Eier dann unbewusst aus.[1]

Synodontis lucipinnis

provided by wikipedia EN

Synodontis lucipinnis is a species of upside-down catfish endemic to Zambia, where it is only known from the Musende Rocks area (Mpulungu) of Lake Tanganyika.[1][2] It was first described by Jeremy John Wright and Lawrence M. Page in 2006.[1] The species name "lucipinnis" is derived from a combination of the Latin luci, meaning bright or clear, and the Latin pinnis, meaning fin. This refers to the light coloration in a patch on the base of the fins of this species.[1]

Description

Like all members of the genus Synodontis, S. lucipinnis has a strong, bony head capsule that extends back as far as the first spine of the dorsal fin.[3] The head is about 310 of the standard length of the fish.[1] The head contains a distinct narrow, bony, external protrusion called a humeral process.[4] The shape and size of the humeral process helps to identify the species. In S. lucipinnis, the humeral process is triangular and rough, with a poorly defined ridge on the bottom edge.[1] The top edge is convex and the end is sharply pointed.[1] It is covered with many small, thin, papillae and is about half of the length of the head.[1] The diameter of the eye is about 17 of the length of the head.[1]

The fish has three pairs of barbels. The maxillary barbels are on located on the upper jaw, and two pairs of mandibular barbels are on the lower jaw. The maxillary barbel has a narrow membrane attached near the base and is straight without any branches.[1] It extends at least as far as the base of the pectoral spine, about as long as the head.[1] The outer pair of mandibular barbels extends just past the front of the pectoral girdle, about 12 of the length of the head,[1] and contains four to six short, weak branches, usually without secondary branches.[1] The inner pair of mandibular barbels is about 13 to 12 as long as the outer pair, about 14 of the length of the head,[1] with four to six pairs of branches, with many secondary branches present.[1]

The skin of S. lucipinnis has a large number of tiny vertical skin folds. The exact purpose of the skin folds is not known, but is a characteristic of the species of Syndontis that are endemic to Lake Tanganyika.[1] papilla are present on the head, but not the body.[1]

The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines.[4] In S. lucipinnis, the spine of the dorsal fin is short, about 23 as long as the head,[1] slightly curved, smooth on the front and serrated on the back, and ends with short, white filament.[1] The remaining portion of the dorsal fin is made up of seven branching rays and one unbranched ray.[1] The spine of the pectoral fin is slightly curved, about as long as the dorsal fin spine, smooth on the front and with large serrations on the back.[1] The pectoral spine ends in short, white filament.[1] The rest of the pectoral fins are made up of eight to nine branching rays.[1] The adipose fin does not contain any rays, is long and well developed, and has a convex shape.[1] The pelvic fin contains one unbranched and six branched rays.[1] The front edge of the pelvic fin is vertically aligned halfway between the back end of the dorsal fin and the start of the adipose fin.[1] The anal fin contains four unbranched and eight to nine branched rays; it is vertically aligned with the center of the adipose fin.[1] The tail, or caudal fin, is forked, with rounded lobes, and contains eight rays on the upper lobe, nine rays on the lower lobe.[1]

The mouth of the fish faces downward and has wide lips that contain papilla.[1] All members of Syndontis have a structure called a premaxillary toothpad, which is located on the very front of the upper jaw of the mouth. This structure contains several rows of short, chisel-shaped teeth. In some species, this toothpad is made up of a large patch with several rows in a large cluster. In other species of Syndontis, this toothpad is clearly divided into two separate groups, separated by a thin band of skin that divides the toothpad.[1] This character is used as a method of differentiating between two different but similar species of Syndontis.[1] In S. lucipinnis, the toothpad is interrupted, or separated into two distinct groups.[1] On the lower jaw, or mandible, the teeth of Syndontis are attached to flexible, stalk-like structures and described as "s-shaped" or "hooked".[4][3] The number of teeth on the mandible is used to differentiate between species; in S. lucipinnis, there are 35 to 51 teeth on the mandible, arranged in six short rows.[1]

Some of the species of Synodontis have an opening or series of openings called the axillary pore. It is located on the sides of the body below the humeral process and before the pectoral fin spine. The exact function of the port is not known to scientists, although its presence has been observed in seven other catfish genera. Fish in the genus Acrochordonichthys are known to secrete a mucus with toxic properties from their axillary pore, but there is no scientific consensus as to the exact purpose of the secretion or the pore.[1] S. lucipinnis does not have an axillary pore.[1]

The back of the fish is yellowish to copper brown, and is covered with large, irregularly shaped black spots.[1] The underside is lighter, with more regularly shaped black spots.[1] Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. lucipinnis, and the back edges of the fins are white in color.[1] In addition, the fins have large, lightly-colored windows at the bases, most noticeable in the dorsal and anal fins.[1] The caudal fin has a black bar that runs from the base of each lobe to the top of the fin.[1] The barbels are white.[1]

The maximum standard length of known specimens is 8 centimetres (3.1 in) with a total length of 10 centimetres (3.9 in).[1][2] Generally, females in the genus Synodontis tend to be slightly larger than males of the same age.[5]

Habitat and behavior

In the wild, the species is endemic to Lake Tanganyika, which has an observed temperature range of 22 to 26 °C (72 to 79 °F), an approximate pH of 8.5 – 9, and dH range of 4-15.[6][2] The exact habitat is unknown, but like other small species of Syndontis, it probably inhabits fairly shallow, rocky coastal areas.[1] The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.[1] Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.[7] As a whole, species of Synodontis are omnivores, consuming insect larvae, algae, gastropods, bivalves, sponges, crustaceans, and the eggs of other fishes.[1] The growth rate is rapid in the first year, then slows down as the fish age.[5]
