Broadnose cat shark

The Broadnose Cat Shark (Apristurus investigatoris) is a species in the genus Apristurus. It is currently classified as Least Concern on the IUCN Red List. Typically found in marine environments from coastal waters to deep ocean.

Phacus hamelii is a unicellular, photosynthetic euglenoid alga with a flattened, asymmetric cell body containing chloroplasts and a distinctive posterior tail-like extension. It inhabits freshwater environments including ponds, ditches, and slow-moving water bodies rich in organic matter. Like other Phacus species, it uses a flagellum for locomotion and can perform both photosynthesis and heterotrophic feeding.
