Newly Discovered Saltwater Species

I know that every few months we (researchers) tend to find new species that are living in either closed-off environments or those that are living in the deep sea that we have yet to completely explore (more of the new species tend to come out after a hurricane or a tsunami due to the waves pushing them up and forward to the surface).

I think there is a bunch of things we can learn, from how they have evolved to live in those conditions to even what they do for food sources and day-to-day suriving in harsh conditions.

What is so sad is that so many animal species go extinct. What is the rate for fish you think? I am sure it is a lot. What might be the causes of such extinctions?
