Blondie...

...is the nickname of this Protoreaster sp. (?), which differs from most of the other knobbly sea stars on Cyrene Reef in its bleached epidermis with small, pale knobs that radiate on a fine mosaic of dark pixels. It's also not as well-endowed as the newly recorded Pentaceratser mammillatus with its rim of marginal spines. Amidst our intrusions into its domain, this asteroid maintains a bearing of calcified stiffness, guarding its secrets and spilling no guts during our short stumble through its territory in a rare and precious hour of tidal latitude.
