Family Ophidiasteridae:
About "Linckia" Stars: There are a great many
seastars sold as Linckia/Linckia spp. that are decidedly of other
genera. Some are not peaceful bacterial et al. detritus feeders as the
"true" Linckias of many colors (and at least two species). Do
make sure and get a positive identification to species, and research
the nutritional, and system size and type needs before purchasing
stars. The true Linckias are good choices where available in initially
healthy condition, and placed in established, large systems (at least a
hundred gallons) with plenty of live rock, detritus to feed on, and not
too many competitors. Named in honor of J.H. Linck who wrote a
monograph of seastars in 1733. Tropical Atlantic and Pacific.
| Linckia columbiae the Fragile Seastar.
Semi-tropical Linckia species found in the eastern Pacific. One off

|
| Linckia guildingi Gray 1840, the Green

with low, hard nodules. Though called "green" occurs in
other colors (tan, beige, brown, blue, reddish). Found in Indian, Pacific,
Atlantic Oceans and Caribbean. Big Island Hawaii
