In terms of the different color morphs, most people generally want to know if they all behave the same, or whether different colors of sea stars have different behaviors in the aquarium. The simple answer to that question is maybe. The problem is that there is quite a bit of natural variation in color among collected from different areas, and there are some regions where are almost always brilliant blue, while in other areas the stars may be predominantly pale, brownish, or even orange in color. Given that the taxonomy of the group is a little fuzzy still, and we're not even really sure of the species, the importance of differences between the color morphs are somewhat hard to pin down, exactly. What is known about is that the animals gets their color from a blue pigment called linckiacyanin and some accessory yellow carotenoids that give the star its rich blue color . Depending on the exact ratio and combination of pigments in the star, the colors of the starfish can range from blue, to brown or orange, but it is not clear whether there are any behavioral or ecological differences among sea stars that have these different colors. Although certain color variations are more common in some areas than others, researchers do not know whether these color differences result from some ecological or genetic differences among the sea stars.

The Vancouver Aquarium made a time-lapse video of a sea star disintegrating. Watch it here: Our predatory sea star tank is empty because of Sea Star Wasting Syndrome (SSWS). Most of the predatory sea stars had been at the Aquarium close to 30 years and we are very sad they are now gone after succumbing to the disease.

As you may have seen in a recent , some sunflower stars in British Columbia, Washington and California—and even along the Seattle waterfront—have been suffering from a condition that gives the impression of “melting.” The cause of this condition is currently unknown, but as a precaution, the Seattle Aquarium has removed sunflower stars from our exhibits and placed them under quarantine until more can be learned.

In the wild, the Blue Linckia Sea Star is found in the sunny areas of the reef and reef fringe, constantly foraging for food. In the home aquarium setting, the Blue Linckia Sea Star prefers a well-lit sandy or coral rubble substrate, with many rocky hiding places. As a juvenile (when it has a blue-green coloration), the Blue Linckia Sea Star spends most of the day hiding in small caves or overhangs. As a larger adult, it can be seen anchored to the rocks or glass, waving one or two arms in the water, searching for small, free-floating microbes. The Blue Linckia Sea Star is generally solitary, but it will tolerate other starfish and amiable fish in the aquarium.Also known as the Nodular Sea Star, or Chocolate Chip Starfish, the Chocolate Chip Sea Star naturally inhabits a fairly large habitat. Though most commonly found in shallow lagoons, the Chocolate Chip Sea Star can also be found at depths down to 75 feet deep in the Indo-Pacific reef region. A large aquarium with open access to a mature sand bed several inches in depth best recreates the preferred habitat of the Chocolate Chip Sea Star. While relatively hardy, the Chocolate Chip Sea Star requires particular attention to water quality. Like many invertebrates, the Chocolate Chip Sea Star requires high water quality and will not tolerate high nitrate levels.
