Once Abundant Shark Species Nearly Vanishes in Just 40 Years

"Smalltail shark populations have declined by 90% in Brazil, and new research finds that overfishing has pushed the species perilously close to extinction."

"Oh what a difference a few decades make.

Back in in the 1980s and 1990s, a species known as the smalltail shark (Carcharhinus porosus) was one of the most common fish caught off the coast of northern Brazil.

That’s not the case anymore. A new paper by researchers from a trio of Brazilian science institutions calculates that smalltail shark populations in the country have declined by a shocking 90%. They say the species has now become critically endangered and is in need of “urgent conservation methods…to prevent its extinction in the near future.”

The problem, as with so many other declining oceanic species, stems from rampant overfishing."
