Wild Fact #948 – This Mollusk Just wants to be Left Abalone – Northern Abalone


I read a press release from Fisheries and Oceans Canada today regarding the Northern Abalone.  I will discuss some of the details and provide a link to this article at the end of today’s fact.  Until then though, I am going to entertain you with some interesting facts about the northern abalone (aka Pinto Abalone).

You may be asking yourselves, what the heck is an abalone? Don’t worry, I am sure you are not the only one scratching their head at this one.  Luckily, I am going to tell you what an abalone is right……now.  The northern abalone is a mollusk.  Basically, it is a large sea snail.  The pinto abalone is usually about 4″ long but can grow to about 6″ long. They have a flattened, ear shaped shell that is generally a greenish brown colour but can also be white or blue.  The inside of the shell is irridescent like most sea shells and change colour depending how you look at it. The shape of this shell protects the mollusk as well as reduces the resistance of water flow.

Does anyone know one of the factors that influences the colour of the northern abalone?  Well, the colour varies depending on the algae pigments surviving in the waste products on top of the shell.  So now this poses the question as to how the waste products get on top of their shell.  This is easy to answer.  The abalone puts it there.  You see, they have 5 openings on top of their shell that helps them survive by assisting with daily functions.  Clean water and oxygen enters through these holes while the waste and carbon dioxide exit the body through these exit points.  During the spawning season the abalone will also release their spawn through these holes.  These openings are very important for the abalone and sometimes will require maintenance.  Every now and again the northern abalone will stick their tentacles through the openings to ensure they are clean and free of debris.  After all they wouldn’t want this major life support system backing up.

All right, I mentioned that I would tell you about the article that inpired today’s post, so here it is.  First of all, you need to know that northern abalone are a threatened species according to the Federal Species at Risk Act (in Canada).  Well, the Canadian Government worked with officials from the United States of America and Mexico to successfully charge a company for illegally possessing northern abalone.  This three year investigation resulted in a $25 000 fine.  Similarly, through this investigation another company was fined $35 500 for illegally possessing abalone.  Some of this money will be redirected back to the Canadian Government to promote conservation and protection of northern abalone. This is a huge victory for all Governments invovled and will hopefully help educate the public about the importance of all species at risk.  To read the story then please click here.

Thanks for letting me talk and try to get my message about Species at Risk out to the public.  Have a great day!
