You deserve to get raped the next time you go outside slut

did you know that green spoon worms begin life all the same- in a sexually undifferentiated larval state, their sex only being determined on where they land?? if the larva lands on the seafloor it becomes female and starts secreting a toxin, if this toxin comes in contact with a larval spoonworm that worm will become male and be pulled into the females proboscis. For the rest of its life that male will live in the females genital sac to provide her sperm

Green Spoonworm (Bonellia viridis)

...is a species of Echiruan or spoonworm found in the north-eastern Atlantic, Indian, and Pacific oceans, and the Red and Mediterranean and Red seas. Green spoonworms are highly sexually dimorphic, the females take the green form you see above, the males however are planktonic and live inside the females body. The presence/absence of the pigment bonellin determines sex. Green spoonworms are mainly detritivores and will anchor themselves to the floor with two hooks. They will also feed on small invertebrates aswell by using an extendable proboscis which is 10x their body size.
