Oyster

Oyster

The Oyster is the most advanced animal of our time. The statement is true if you ignore the benefits of civilisation ( Which are very questionable)

It is in fact a large stomach and the minimum of other organs. It’s digestion is intracellular, and it’s excretion is passed to the outlet by cilia. The blood also passes through the epithelium ( Stomach or tubules walls) The adductor was originally the posterior of the Oyster, and has only one Aorta to serve it including the rectum and the anus. The rest of the body has the other namely the Anterior. There is but one Ventricle for all the body.

Ostrea Edulis

Approximately 3 ½ “ Dia. consumes 2 ½ gallons per hour at 15 degrees C

American Lurida Due to anatomical reasons it consumes 8 gallons per hour at 24 degrees C

Ostrea Edulis Liberates 1 million fertilized eggs at one spawning

Crossostrea Virginica USA Liberates 15-115 million un fertilized eggs in warm water and may spawn more than once. ( That does not surprise me at all taking into account it is American )

Ostrea Edulis Has a heart beat of 18 beats per minute at 17 degrees C

Oyster blood is colourless there being neither red pigment ( Haemoglobin) found in land animals or vertebrates or blue pigment ( Haemocymin ) as in other molluscs i.e. Snails and especially Cephalopods, cuttlefish, Squids, and Octopads.
