I'm sorry, due to the recent numbers of false and mis-information, you must now be registered and logged in before being allowed to update or add creatures and DNA samples. I fought against doing this for a long time but the volume of bogus entries and data has prompted me to enforce this limitation.
Please take the time to register if you have not already done so and login before updating data.
Thank you for your patience in this matter and thank you for helping update the site!
