GOBIFORMES - the gobies

  • Family: Gobiidae
    A species-rich family of mainly marine fish. the pectoral fins are joined to form a sucker. Most species are small and the family includes the smallest fish species known. Some gobies are probably the smallest adult fish in the Amazon and they are common in habitats offering small, enclosed, interstices such as leaf-litter banks and amongst the roots of floating meadow.

    Microphilypnus sp.
    Identification: Easily identified as the only 'goby' in the Taruma-Mirim. In this family the pectoral fins are fused at the base so that the fins form a sucker. During the low water season the length rarely exceeds 20 mm.
    Colour: In life almost transparent with brown dots along the ventral and dorsal surfaces. Preserved, white with black dots.
    Habitat: Within leaf-litter banks.
    Abundance: One of the most abundant fishes within the leaf-litter. Densities average 44.6 individuals per square meter and can reach 560.
    Food: Predator on microinvertebrates
