The Amazon River Dolphin (Inia geoffrensis) is a species in the genus Inia. Its conservation status is listed as Data Deficient, indicating insufficient data for assessment. Typically found in diverse terrestrial and aquatic ecosystems.

Biddulphia rhombus is a centric marine diatom with a distinctly bipolar, rhomboid to broadly lanceolate valve shape bearing prominent horn-like elevations. It inhabits coastal planktonic and benthic environments in temperate to warm seas worldwide. This photosynthetic diatom contributes to marine primary production in neritic coastal waters.
