O objetivo neste trabalho foi estudar a distribuição vertical da Anomalocardia flexuosa em uma praia arenosa do nordeste brasileiro. Foram obtidas 135 amostras três meses no ano de 2015. Para testar hipótese entre as densidades nas profundidades até 5 cm (densidade 5) e 10 10) realizado o teste t-Student. Modelos Lineares Generalizados foram aplicados para estimar variável resposta densidade co...

Huge tsunami waves associated with megathrust earthquakes have a severe impact on shallow marine ecosystems. We investigated the impact of a tsunami generated by the 2011 M9.0 Tohoku-Oki earthquake on the seafloor and large benthic animals in muddy and sandy ria coasts (Otsuchi and Funakoshi bays) in northeastern Japan. We conducted underwater field surveys using scuba equipment in water depths...

An unnamed microcercous cercaria (Digenea: Monorchiidae), a parasite of Amiantis purpurata (Lamarck, 1818) (Bivalvia: Veneridae) and its corresponding metacercaria from the province of Buenos Aires and the Patagonian coast of the Southwest Atlantic Ocean, are described. The cercaria described in this paper differs from the three other monorchiid microcercous cercariae, i.e., Lasiotocus minutus ...
