Crassostrea is a genus of true oysters (family Ostreidae) [2] containing some of the most important oysters used for food. The genus was recent split in WoRMS, following the DNA-based phylogenies of Salvi et al. (2014 and 2017). Pacific species were moved to a new genus Magallana. C. zhanjiangensis became Talonostrea zhanjiangensis. [3]
Crassostrea rhizophorae, also known as the mangrove cupped oyster, is a species of bivalve in the family Ostreidae. [1] [2] C. rhizophorae is one of the predominant oyster species in the South Atlantic, specifically in Central and South America. [1] [3] It is often found in the vast mangrove ecosystem along the coast of Brazil. [1]
An assortment of shells of marine bivalves and a few marine gastropods found on a beach in Wales. In May 2010, a new taxonomy of the Bivalvia was published in the journal Malacologia.
Oestroidea have a wide range of feeding habits and breeding environments: saprophagous (many Calliphoridae and Sarcophagidae), feeding on blood of birds or mammals (some Calliphoridae), parasites of gastropods or earthworms (some Calliphoridae), parasitoids of arthropods (Rhinophoridae, Tachinidae and some Sarcophagidae), living in association with termites or ants (some Calliphoridae and ...
