Triploid Atlantic salmon are not more susceptible to sea louse infection than diploid fish, according to a study by Benedikt Frenzl et al, University of Stirling, UK.
A new study has shown that the dottyback, a small predatory reef fish, can change the colour of its body to imitate a variety of other reef fish species, allowing the dottyback to sneak up undetected and eat their young.
