Brittle-star definition, any echinoderm of the class Ophiuroidea, having the body composed of a central, rounded disk from which radiate long, slender, fragile arms. See more. Brittle stars are nocturnal scavengers that can be found in ecosystems throughout the world’s oceans. These animals consist of a clearly defined circular or pentagonal central disk surrounded by five long, slender arms. Sizes can vary by species and can range from 8 inches in diameter to 20 inches in diameter. Size 8 inches to 20 inches (

The authors describe 24 species of brittle stars, 8 sea urchins and 2 feather stars inhabiting the coastal waters of BC, the Alaska Panhandle and Puget Sound. All species described live in the shallow waters to a depth of metres; but the authors include species . Brittle Stars can be very interesting pets because of how fast they can move and how they are quite active at night. They can make any tank more enjoyable and any other animal in the tank more boring and they don't endanger any of the coral in the tank so its .

Generally, brittle stars live below m of depth. There are two related groups of Ophiuroids: the Ophiurida (brittle stars) and the basket stars (Eurialida). Basket stars usually live in the deeper parts of the range. Brittle stars are mostly scavengers and detrivores, able to . Some people and books call these starfish brittle stars, and they are closely related, but we prefer to call all the smooth legged starfish serpent stars, and the spiny-legged stars brittle stars. Serpent and brittle stars are easy to care for in an aquarium and will eat most foods offered to them.

Rod Val Moore is a natural poet, and his imaginings of the twin Blister and Brittle stars, and the planet that shares them, are truly beautiful. I would highly recommend this book to anyone, but don't come to it expecting a neatly-packaged story or you will walk away disappointed.

The morals within are subtle, and often shift like desert sands/5. Brittle stars are measured by the diameter of the central disc, and the length of their arms. Brittle star discs range in size from to 3 inches; their arm length is a function of their disc size, typically between two to three times the diameter although some have lengths up Brittle stars book 20 or more times.

"Brittle Stars " was the first of Lichen's "Uncommon Field Guide" series I discovered. They are all uncommonly delightful to poke into. One can read them chapter-by-chapter or just open the book anywhere and delve in. I picked up this one to add to my school's marine biology collection.

After scanning it, I bought a second copy for myself/5(8). Brittle star, also called serpent star, any of the 2, living species of marine invertebrates constituting the subclass Ophiuroidea (phylum Echinodermata).

Their long, thin arms—usually five and often forked and Brittle stars book distinctly set off from the small disk-shaped body.

The arms readily break off but soon regrow—i.e., are regenerated. Among the basket stars, a type of brittle star. Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to crawl across the sea floor using their flexible arms for locomotion.

The ophiuroids generally have five long, slender, whip-like arms which may reach up to 60 cm (24 in) in length on the largest m: Animalia. Brittle stars (Ophiuroidea) are a group of echinoderms that resemble starfish.

There are about species of brittle stars alive today and most species inhabit marine habitats with depths greater than feet. There are a few species of shallow water brittle stars. These species live in the sand or mud just below the low tide mark. Echinoderms, including feather stars, seastars, brittle stars, sea urchins and sea cucumbers, are some of the most beautiful and interesting animals in the sea.

They play an important ecological role and several species of sea urchins and sea cucumbers form the basis of important fisheries. Over species live in Australian waters, from the shoreline to the depths of the abyssal plain and.

The arms connect to a central disk, and it’s relatively easy to tell where the arm ends and the disk begins. Next, look at how they move.

Brittle stars are very closely related to starfish or sea stars. Like starfish, brittle stars are echinoderms. However, brittle stars have thinner, more fragile arms than true starfish do. In addition, brittle stars are more agile than starfish. Both starfish and brittle stars are capable of moving very quickly, but brittle stars are even faster.

Sea stars occupy every type of habitat, including tidal pools, rocky shores, sea grass, kelp beds, and coral reefs. Some sea stars even live in sands as deep as 20, feet (9, meters). Sea stars aren’t social creatures, but they will congregate in large groups during certain times of the year to feed.

Brittle stars feed by extending their lengthy arms to snatch nutritious particles falling in the water column. A previous study of corals in New Zealand fjords showed that a mutualistic sea star was able to brush away potentially smothering sediments following catastrophic.

Brittle stars occur in incredible numbers on the sandy seafloor. In kelp forests near La Jolla in southern California, millions of them may carpet the seafloor in layers up to an inch thick.

Brittle stars live in a wide range of water depths — from the shoreline down to 6, feet (2, m). The brittle stars reveal that it’s also a place where new species are born, independently of what occurs on the surface.

The abyss is both cradle and crucible. This Section focuses on the brittle stars, as very little work has examined acquisition of gametes from the basket stars. Brittle stars arguably are the most diverse group of echinoderms, exhibiting an extensive array of distinct reproductive and developmental modes, which makes them difficult to characterize in general terms (reviewed in Byrne.

Habitat. Today, brittle stars are almost omnipresent in the world’s oceans. They are found in virtually all habitats, from the intertidal zone down to depths of more t feet (7, m). In coral reefs and adjacent habitats, they are often found in large densities, for example in sediments or the intertidal zone.

Stars and scars Commencing in California in the early days of its union with the US, the story ranges from encounters with Indians, Bounty Hunters, and brutal Civil War battles to tell a tale of revenge and redemption. This is high adventure at its best and it is clear that the author enjoyed herself writing it.

It is well written, full of thrills and excitement, and has a cast of varied and /5(24). The Brittle Star, Ophiocoma sp., is a species of starfish with long, flexible limbs that have small pointed projections across their bodies.

They come in colors of black, brown, and a combination of the two, sometimes having grey bands around some of their limbs.

They require a tank with plenty of live rock to scavenge from, and take refuge in during the day.
