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.

I made a 30 day art challenges cause why not

For 1 month, make and draw a character based off of a species of your choice from each given phylum of animal (some phyla have thousands of species to choose from…others will only have one or two)

You can make them anthros, gijinkas, cartoons, monster, sonic ocs, anything you want as long as it’s at least inspired directly by the critter
