  • Ancient shark fossil reveals new insights into jaw evolution
    The skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates -- including humans -- than do modern sharks, as was previously thought. The new study shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic 'sharkiness' over millions of years.
  • Fish exposed to antidepressants exhibit altered behavioral changes
    Fish exposed to the antidepressant Fluoxetine, an active ingredient in prescription drugs such as Prozac, exhibited a range of altered mating behaviours, repetitive behaviour and aggression towards female fish, according to new research. "With increased aggression, in the highest level of concentration, female survivorship was only 33% compared to the other exposures that had a survivorship of 77-87.5%. The females that died had visible bruising and tissue damage," according to the lead author.

  • Ocean acidification robs reef fish of their fear of predators
    Research on the behavior of coral reef fish at naturally-occurring carbon dioxide seeps in Milne Bay in eastern Papua New Guinea has shown that continuous exposure to increased levels of carbon dioxide dramatically alters the way fish respond to predators.
