A mussel is what is known as a filter feeder; it passes sea water through a filter and eats whatever it traps, which is mostly plankton.
There is no set wage, every team is different, and it depends on the Owner and the Crew Cheif, Johnsons crew chief would make more then a crew chief with no wins. Which bring us to "Bonuses", team members get bonuses with wins and/or championships, this is in the thousands of dollars, so your answer is it varies from team-to-team, win-to-win-to-championship. Hope this helps!
I have answered this question already, short version: varies from team to team. Here is the answer else where in the category. There are several schools of thought and facts, many lessor teams average between $30,000 to $50,000, middle range teams $40,000 to $70,000, top teams $60,000 to $90,000, A few even more, but they are the best of the best. This is a hard question to give exactitudes, the team owner(s) and sponsors determine the wages for crew members, with great sponsors comes huge money.
