Occurrence of Sphoeroides rosenblatti Bussing, 1996 (Teleostei: Tetraodontidae) along the coast of Guayas Province, Ecuador, and a comparison with sympatric Sphoeroides annulatus (Jenyns, 1842) [PDF]
Revista De Biologia Marina Y Oceanografia, 2006 Se recolectaron trece ejemplares juveniles de Sphoeroides rosenblatti Bussing, 1996 en un bosque pequeno y fuertemente impactado de mangle situado en Palmar, provincia de Guayas, Ecuador. Esta especie era conocida previamente solo de aguas costeras de Costa Rica y Panama. Se contrasto la ocurrencia y morfologia de S.

This study provides basic information on the occurrence of platyhelminths in the wild bullseye puffer (Sphoeroides annulatus) from Sinaloa, Mexico. Specimens of pufferfish were collected from 2 localities: Teacapan (n = 161) and Mazatlan (n = 66). Six species of platyhelminths were recorded: 2 monogeneans (Diclidophoridae: Heterobothrium ecuadori and ...

Kudoa dianae sp. n. (Myxosporea: Multivalvulida), a new parasite of bullseye puffer, Sphoeroides annulatus (Tetraodontiformes: Tetraodontidae) [PDF]
Folia Parasitologica, 2002 A new multivalvulid myxosporean species, Kudoa dianae sp. n., is described from bullseye puffer, Sphoeroides annulatus (Jenyns) (Tetraodontiformes: Tetraodontidae). Plasmodia develop in extramuscular sites, in the wall of oesophagus and less frequently on mesenteries.

Reproductive aspects of Sphoeroides annulatus (Jenyns, 1842) (Tetraodontiformes, Tetraodontidae) inhabiting the Mazatlan coast, Sinaloa, Mexico [PDF]
Revista De Biologia Marina Y Oceanografia, 2007 La muestra de Sphoeroides annulatus capturada en la costa de Mazatlan, Sinaloa, Mexico fue predominantemente de adultos, como resultado de una aparente distribucion diferencial por talla/edad de la especie. La proporcion sexual fue 1:1. Las hembras presentaron un crecimiento alometrico y los machos, isometrico. De acuerdo con el analisis morfocromatico

A fragment of a glycoprotein hormone receptor (GpHR) gene was isolated from the ovary of the bullseye puffer. This cDNA fragment showed similarity to the thyrotropin (TSH) and gonadotropin (LH and FSH) receptors. GpHR mRNA expression in the ovary gradually increased during oocyte maturation.
