That reminds me of the time I was on a wreck dive. The DM motioned for me to come over. I took a photo of a beautiful sea turtle. After I took my photo I backed off to let the other two divers take a look. All of a sudden one of the divers grabbed the turtles tail and touching the turtle!! The DM had a look and brushed the divers hand away..I tell you when we ended our dive. The DM let him have it!! I so agreed with the DM!! As divers we are in there world. leave everything alone and also watch where your fins are going !!
