Die Oostelike bottelneus (Mormyrus longirostris) is 'n varswatervis wat voorkom die middel en onderste gedeeltes van die Zambezirivier, Buzi-, Pungwe- en onderste dele van die Saveriviere. Die vis kom ook in die Ruvuma- en Rifijiriviere in Tanzanië, Kongorivier en die Malawimeer en Tanganjikameer voor. In Engels staan die vis bekend as Eastern bottlenose.
Die vis lyk baie soos die Westelike bottelneus, maar het 'n dieper lyf, die kop en snoet is meer geboë, die snoet is langer en die skubbe is kleiner. Die wyfies is kleiner en het 'n nog dieper lyf as die mannetjies. Die vis is olyfkleurig of bruin aan die bokant en ligter aan die onderkant. Die vis word tot 75 cm lank. Zimbabwe se hengelrekord is 9.973 kg en Malawi se rekord is 2 kg.
Die vis verkies stil, diep water met 'n sagte modderige bodem en leef in skole saam. Hulle vreet ongewerweldes, veral inseklarwes en slakke. Hulle is naglewend. Die vis broei in die somer gedurende die reën seisoen. Hulle beweeg stroomop in riviere nadat die watervlak gedaal het. Die wyfie dra 10,000 - 70,000 eiers op 'n keer.

Mormyrus longirostris, commonly referred as the eastern bottle-nosed mormyrid, is a medium-sized ray-finned fish species belonging to the family Mormyridae. It was originally described by Wilhelm Peters in Monatsberichte der Akad. Wiss. Berlin, 1852.[2]
This species grows to a maximum length of 75 centimetres (30 in) and can weigh up to 10 kilograms (22 lb). The dorsal fin is more than twice the length of the anal fin. The dorsal origin is nearer to the tip of the snout than to the caudal fin base.
It primarily feeds on weeds and insects, but also on small vertebrates, such as small fish and fish eggs. They hunt using electricity and can give a mild electric shock to defend itself.
M. longirostris can be found in abundance across the plains of Africa in freshwater habitats, including the lower and middle Zambezi, lower Sabi and Ludi rivers and in the Luapula-Moero-Bangwelo (Zambian Congo system). It inhabits the Ruvuma and Rufiji rivers in Tanzania, lakes Malawi, Tanganyika and Rukwa and other eastward-flowing rivers in Tanzania.
The species lives in caves and muddy areas with soft bottoms. It hides in weeds and characteristically forms small shoals.
Active mostly at night, it breeds during the summer rainy season, moving upstream in rivers after water has receded, with migrations at irregular intervals. Females carry 10,000–70,000 eggs at a time.
The fish is harvested for food with bait and hook.[3]

Tapiirikala (Mormyrus longirostris) on norsukalojen heimoon kuuluva kala. Se on erikoisen muotoinen ja sillä on sähköelin, jonka avulla se suunnistaa. Tapiirikaloja elää Afrikan suurissa joissa ja järvissä. Ne voivat kasvaa jopa metrin mittaisiksi, mutta yleisemmin ne jäävät alle puolen metrin mittaisiksi.[3]
