Swimming speed of a specialist maneuver, Cichlasoma facetum (Jenyns) (Pisces, Cichlidae) in experimental conditions

Parental behavior and some histological features of scales in Cichlasoma citrinellum (pisces, Cichlidae)

Ecological and evolutionary consequences of the trophic polymorphism in Cichlasoma citrinellum (Pisces: Cichlidae)

Cross-fostering and Parent-offspring Responses in Cichlasoma citrinellum (Pisces, Cichlidae)

[Larval development of Hypsophrys nicaraguensis (Pisces: Cichlidae) under laboratory conditions].

The cichlid Hypsophrys nicaraguensis is a popular fish known as butterfly, and despite its widespread use as pets, little is known about its reproductive biology. In order to contribute to this knowledge, the study describes the relevant larval development characteristics, from adult and larval cultures in captivity. Every 12h, samples of larvae were collected and observed under the microscope ...

A morphometric analysis of polymorphism in the pharyngeal dentition of Cichlasoma minckleyi (Teleostei: Cichlidae).

Dental polymorphism in teleost fishes often involves production of a robust dentition, or "molarization", in one morph. The lower pharyngeals of a sample of wild-caught individuals of the polymorphic Cuatro Cienegas cichlid, Cichlasoma minckleyi (Kornfield and Taylor) (Proc. Biol. Soc. Wash. 96 (1983) 253), were measured to investigate morphological changes associated with molarization. Princip...
