Did you know nautilus populations tend to be about 75 percent male and 25 percent female? Scientists aren’t sure why!Telling male and female nautiluses apart is tricky—the only way to know for sure is through dissection. If you’re just using your eyes, the cephalopod’s size can be a clue, as males tend to get larger than females.Learn more about the chambered nautilus
Aquarist Greg Casten is attempting to hand rear a clutch of tiny octopuses for the first time in the UK. Marine expert Greg uses tweezers to feed shrimp to 40 tiny babies at the Weymouth Sealife centre in Dorset and is hopeful that with his help the minute cephalopod’s will survive to adulthood. Only a very small percentage of young octopuses manage to survive to maturity in the wild and Greg is hopeful his clutch will have much greater chances in the safe enviroment of the centre.
