Kangaroos have 3 offspring, a joey thats out of the pouch, one still developing within the pouch and a embryo thats on pause. The pregnancy period last for around 30 days with the mother taking care of the joey for the next 9 months, helping them to grow a strong bond therefore they would be K selection. The thorny devil lays 8-10 eggs at one time in a burrow dug by the female, there they are incubated for 3-4 months before they dig their own way out. Although the amount of eggs at one time is quite small the amount of care they give puts them more closer to r selection than say kangaroos, but are more leaning towards K selection. Skinks lays 6 eggs per clutch and in total 250 eggs, therefore they're r selection.
Scorpion weed Probably based in colour that it would be transported by insects as they're a bight purple colour. They give off a scent but not a very good one according to humans. They have petals which i would assume could be landing pad for the insects.
