The Big eye thresher shark (Alopias superciliosus) is a species in the genus Alopias. It is currently classified as Vulnerable on the IUCN Red List. Typically found in marine environments from coastal waters to deep ocean.

Hemiselmis anomala is a unicellular cryptomonad alga found in marine and estuarine environments, characterised by its asymmetric, kidney-shaped cell and two unequal flagella for swimming.
