Inheritance Pattern of Lateral Dimorphism in Two Cichlids (a Scale Eater, Perissodus microlepis, and an Herbivore, Neolamprologus moorii) in Lake Tanganyika
Abstract Antisymmetry in the direction of the mouth opening, to either the right (“lefty”) or left (“righty”), was documented in the scale-eating cichlid Perissodus microlepis. This study revealedExpand

Asymmetry of Mouth Morph of a Freshwater Goby, Rhinogobius Flumineus
Abstract Morphological analysis of a small freshwater goby, Rhinogobius flumineus, showed a distinct dimorphic asymmetry in the lower jaw. The mouth of each fish opened with a slight but definiteExpand

A new hypothesis for species coexistence: male–male repulsion promotes coexistence of competing species
We propose a new hypothesis for species coexistence by considering behavioral interactions between individuals. The hypothesis states that repulsive behavior between conspecific males (male–maleExpand

Coexistence mechanisms of permanently territorial fishes proposed hitherto have been mainly based on interspecific competition. To test the hypothesis of the coexistence through male-matingExpand

Description of alternative male reproductive tactics in a shell-brooding cichlid, Telmatochromis vittatus, in Lake Tanganyika
Telmatochromis vittatus (Cichlidae) is a Tanganyikan substrate brooder which spawns in the gastropod-shell nests of a cichlid, Lamprologus callipterus. We describe male reproductive tactics of T.Expand

Male–male competition for large nests as a determinant of male mating success in a Japanese stream goby, Rhinogobius sp. DA
Abstract Males of the stream goby Rhinogobius sp. DA (dark type) court females in deep pools and care for the eggs under stones in shallow riffles. We studied male–male competition for access toExpand

Geographical colour variation in cichlid fishes at the southern end of Lake Tanganyika
SynopsisGeographical colour variation and distribution of 48 common cichlid fish species were studied at 20 sites along an 85 km shoreline at the southern end of Lake Tanganyika, Africa. SixteenExpand

Sperm drinking by female catfishes: a novel mode of insemination
SynopsisWe report on unique reproductive behaviour and a new mode of egg insemination in a small catfish Corydoras aeneus (Callichthyidae). A male courts a female by presenting his abdomen to her.Expand

Territoriality of male cichlid fishes in Lake Tanganyika
– Intra- and interspecific territoriality of males in six maternal mouthbrooding cichlid species was observed in Lake Tanganyika. Males of all species usually swam, foraged and courted visitingExpand

Social system and reproduction of helpers in a cooperatively breeding cichlid fish (Julidochromis ornatus) in Lake Tanganyika: field observations and parentage analyses
It is suggested that some fish of the genus Julidochromis, substrate-brooding Tanganyikan cichlids with biparental care, breed cooperatively with helpers. We studied the social system of J. ornatusExpand
