Relationship between the size of Pseudamphithoides bacescui (Amphipoda, Gammaridea) and the size of pods of algae
The ampithoids are benthic amphipods that are related to algae in shallow water. The aim of the present study was to determine, for the first time, the relationship between the size of Pseudamphithoides bacescui and the size of the leaves of algae used for the construction of the shelter in the Sisa...

The ampithoids are benthic amphipods that are related to algae in shallow water.
