backround was tent used by bride to dress in for outdoor ceremony. This is the last picture of the day. Vows said, food eaten, cake cut, boquet tossed, guests have gone.
this was done with derwent watercolor pencils in moleskine watercolor notebook. It is actually alot darker in the backround but the scan could not pick up the sketchy pencil marks of the red that I used, Not sure why. I really want to loosen up and this helping with my sketching.
TAXONOMY
Kingdom: Animalia
Phylum: Echinodermata
Class: Asteroidea
Order: Valvatida
Family: Oreasteridae
Genus: Protoreaster
Genus/species: Protoreaster nodosus
GENERAL CHARACTERISTICS: The backround body color is highly variable; may be beige, brown, orange, red or other hues, such as green or blue. Horn-shaped tall dark nodules are conical and arranged in a single row, radially on the dorsal (top) side. Most horned sea stars found are a roughly rigid five-pointed star-shape (occasionally 4 or 6) with tapering arms to the end. Their skeleton is made up of many calcified plates that move like flexible joints and is covered by a spiny skin.
Diameter up to 30 cm (12 in).
DISTRIBUTION/HABITAT: Red Sea, Indian and western Pacific oceans. Found in shallow sheltered sand and seagrass beds.. Depth range Depth range 1 - 582 m (3.3 - 1900 feet).
DIET IN THE WILD: The mouth is located ventrally (bottom). The star covers its food, then pushes out its stomach from inside its body of prey. Sea stars have a unique adaptation for consuming bi-valve mollusks (oysters, clams, mussels, etc.). Stars insert a portion of their stomach into the small “gape” between the valves of a mollusk. Stomach enzymes are released and digest the fleshy part of the mollusk inside its own shell. The digested contents are moved back into the sea star leaving an empty bi-valve shell. P. nodosus prefers sponges, corals, clams and snails, other invertebrates; also opportunistic carrion feeders.
REPRODUCTION: P. nodosus is a broadcast spawner. As in other sea stars, fertilization is external. Eggs and sperm are stored in the rays and released simultaneously. Larvae look nothing like the adults. The form that first hatches from the eggs is bilaterally symmetrical and planktonic. Larvae eventually settle and transform into tiny sea stars.
PREDATORS: Triggerfish, pufferfish, boxfish and parrotfish.
CONSERVATION: IUCN Not Evaluated
REMARKS: The Chocolate Chip Seastars are also called “knobbly sea star” and the “horned sea star.”
The chocolate chip sea star can regenerate lost limbs, as long as the central disk of the body is intact.

Made myself a black backround to shoot against, well a dark blue blanket hung over the curtain rails...Just a few test shots, will be posting some portraits up in a few days so thought I should test the backround first!
