The Aestivation Chamber of the Giant Earthworm Glossoscolex bergi (Glossoscolecidae) in the Subtropical Rainforest of Misiones (Argentina)

Mostrar todas las versiones(2)

Glossoscolex bergi (Glossoscolecidae) is a giant earthworm from the rainforest of Misiones (Argentina). The large size of its aestivation chamber and the meniscate burrows connected to it allow us to describe morphological details and reinterpret some characteristics of the fossil counterpart Castri...
