Maree found this on the shore. It's weird that they turn blue after they die.

"Lobsters, like shrimp and crabs, are members of the decapod family, meaning "ten feet". Decapods have five pairs of walking legs, although the first pair have evolved into pincers, and they have another three pairs of legs that are mandibles used for feeding. These crustaceans' shells change pigment from brown to greenish-blue to a bright red to red-brown after cooking. This is due to the same family of pigment as the carotene in carrots, called astaxanthin. Astaxanthin is a compound pigment that is a combination of xanthin, the blue, green and brown pigments, and astacin, which is bright red and pink. Astacin, unlike xanthin, remains stable after cooking, thus the red color of lobster after cooking. "
