Short description आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण): 0; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 28-37; गुदा कांटा 0; ऐनल सौफट रेज़: 23 - 27; जानवरों की रीड़ का जोड़: 39 - 41. Diagnosis: Dorsal fin up to 1.5 times in length of anal fin; origin of dorsal fin in advance of anal fin (Ref. 52193). Snout rounded, in front of mouth; eye well above mouth; chin with fleshy bulge (Ref. 4967). For distinguishing between specimens of Cyphomyrus discorhynchus en C. cubangoensis, the most useful anatomical characters are: longer dorsal fin length, longer anal fin length, higher number of dorsal fin rays and anal fin rays, and a higher caudal peduncle depth and caudal peduncle length ratio in C. discorhynchus than in C. cubangoensis (Ref. 119538).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Nocturnal shoaling species; favors large river channels with a soft bottom and fringing vegetation (Ref. 7248, 52193). Found mainly in sheltered bays, lagoons and swampy areas; occurs also in typical sandy or rocky rivers (Ref. 13337). Feeds on bottom-living invertebrates (Ref. 52193) and insect larvae at night (Ref. 5595). Known to migrate up tributary rivers of Lake Kariba during rainy season, though it is not yet clear whether this is a breeding migration (Ref. 13337). Breeds during summer rainy season; females carry up to 5,000 eggs (Ref. 7248).
