Feather Duster Worms
Scientific Name: Sabellastarte sp.
Range: West Central Atlantic and Eastern Pacific
Diet: Filter Feeder: eats plankton
Bio:These worms create a leathery tube for protection and to support their soft body, which is made of segments. Each segment has its own organs and muscles. These worms have a feathery crown that extends from the tube and is used for filter feeding and respiration.
Coral Banded Shrimp
Scientific Name: Stenopus hispidus
Range: Western Atlantic and Indo-Pacific Oceans
Diet: Scavengers and also cleans and eats parasites, algae, and dead tissue off of other marine organisms
Bio:Living three to five years, a pair of coral banded shrimp will mate for life. This species is considered a "cleaner" shrimp, as they remove and eat parasites and injured tissue from various reef animals.
Scientific Name: Plerogyra sinuosa
Range: Red Sea, Indian Ocean, and the west Pacific from the East China Sea to Australia
Diet: Photosynthetic single-celled organisms, zooxanthellae that provide the bubble coral with nutrients; also eat planktonic organisms and absorbs dissolved organic matter.
Bio:The bubbles in this coral are filled with zooxanthellae (single-celled organism) which perform photosynthesis for bubble coral; during the day the "bubbles" expand with water so that the zooxanthellae can obtain more sunshine. In the wild, colonies can grow up to three feet long and become active at night, using their tentacles to locate bits of food.
Bat Sea Star
Scientific Name: Patiria miniata
Range: Alaska to Baja California
Diet: Omnivore and Scavenger: surfgrass, algae, colonial tunicates, sponges, and other meaty food found on ocean floor.
Bio:This sea star can have four to nine arms. If an arms is lost, it can take up to a year to regrow. This species has been known to live up to sixteen years in captivity.
Scientific Name: Salmacis sphaeroides
Range: Western Pacific Ocean
Diet: Eats algae, other urchins, sea pens and jellyfish
Bio:Active at night, these bicolored urchins are cannibalistic, meaning they will eat each other!
Scientific Name: Lytechinus variegatus
Range: Bermuda to Brazil
Diet: Eats algae and scavenges the ocean floor for food
Bio:These urchins range in color from green, tan, pink or purple. They use rocks, shell pieces, algae and other materials to cover themselves for camouflage in their environment.
Scientific Name: Cassiopeia sp.
Range: Southern Gulf of Mexico, Caribbean, and other tropical waters
Diet: Photosynthetic single-celled organisms, zooxanthellae that provide the jelly with nutrients
Bio:This jelly has a mutualistic relationship with zooxanthellae (a single-celled photosynthetic organism) that lives in its tentacles. Zooxanthellae provides the jelly with nutrients, and, in turn, the jelly protects the zooxanthellae and gives nitrogen and carbon dioxide. These jellies swim upright but turn upside down to rest on the ocean floor.
Scientific Name: Ophiarachna incrassata
Range: Eastern Africa and Madagascar, Red Sea, Seychelles, Tanzania, West Indian Ocean
Diet: Scavengers but will hunt small fish and invertebrates
Bio:This star is not a sea star, but belongs to a different group called brittle stars. Brittle stars do not have suction cups like sea stars; instead they have small spines. These animals have flexible arms used for movement and the spines give the arms traction. These stars can live between 11 and 20 years in captivity.
Purple Sea Urchin
Scientific Name: Strongylocentrotus purpuratus
Range: Alaska to Baja California
Diet: Mostly eats algae
Bio:Sea otters are one of the main predators of purple sea urchins. Sea otter bones have been found stained purple from this sea urchin's pigment!
Pink Spiny Sea Star
Scientific Name: Pisaster brevispinus
Range: Alaska to California
Diet: Eats mostly bivalves but will also eat snails, sand dollars, barnacles, polychaetes, scavenges meaty pieces
Bio:Facts: 1. Will fight the sun star (Pyconpodia helianthoides) for food 2. Can extend the tube several centimeters to pull bivalves out of the sediment 3. Spawns in Washington during Spring and Summer 4. Usually is pink but can be yellow, brown, purple, and orange colors as well Can Visitors Interact? Viewing tank
