Six-rayed Sea Star
Blood star… why are you such a simple but complex being??? After hours of drawing and redrawing I think I’ve reached a star that I like and that represents the many blood stars I’ve seen hidden in between rocks. Next up I will spend days agonizing over the leather star
Working on this blood star right now what’s your favourite sea star species?

A Star Is Born
Much like their echinoderm cousins, the sea urchins, sea stars (such as this Luidia sarsi) possess a variety of larval forms that can look quite different from their adult forms.
One of these forms is the bipinnaria larva—the elongated, transparent, tentacled thing you see in the first image. As the bipinnaria floats with the plankton, feeding and growing, a juvenile sea star begins to develop at its oral end, looking vaguely star-shaped, but not quite there yet.
The juvenile L. sarsi soon outgrows its larval form (which it absorbs), and sets out to begin life as a young star. *tear*

Can you guess which celestial ocean dweller this belongs to?
*Spoiler!*— It’s a sea star
Sea stars creep along the seafloor using hundreds of little tube feet. These tube feet function through a water vascular system that extends and retracts the feet using hydraulic forces.

Bat stars love to eat urchins, and there’s a massive overpopulation of urchins on this stretch of coastline, so they have food galore. If you go tide pooling you’re almost guaranteed to see one. Their colors range from white to magenta to brilliant red to yellow and everything in between, so they really pop out ~
