Patrik Good Don't you like when nudis try to measure up with other creatures underwater? Here a hiding prawn and what is probably a Gymnodoris alba (a nudikiller as far as I know), size about 8 mm, found Seaway Southport QLD, 28/10/2011, 3metres deep. Found the nudi only cataloguing the prawn picture (which it's heavily cropped).
Patrik Good Are Gymnodoris alba direct developers or do they have veligers?
Gary Cobb I dont think they are direct developers because they don't have permanent food sources to lay their eggs upon! Like Glossodoris vespa. http://www.nudibranch.com.au/pages/vespa.htm
