Ophiuroidea (Brittle and Basket Stars) | Encyclopedia.com The basket stars are the largest ophiuroids; Gorgonocephalus stimpsoni can measure up to 27.5 in (70 cm) in arm length with a disk diameter of 5.63 in (14.3 cm). The branching of the arms in basket stars is repeated in the formation of smaller and smaller units in a fernlike manner. The upper surface of the disk in ophiurid ophiuroids is ... Characteristics - *Brittle Stars* -Brittle Stars are very fragile and can cast off one or more arms if disturbed or caught by a predator. These breaks can occur anywhere beyond the disc and the lost portions can be regenerated. Realistic Cladogram of animal: *Picture to the left* -Shows how brittle stars evolved to become stars, yet not fully develop into a thicker star.

Brittle Star: Fascinating Sea Life - ThoughtCo The largest known brittle star is Ophiopsammus maculata, with a disk measuring 2-3 inches across, and arm length between 6-7 inches. They weigh between 0.01-0.2 ounces and come in a wide variety of colors. Some are even capable of bio-luminescence, generating their own light. Species Sea Star Anatomy 101 - ThoughtCo Sea stars are echinoderms, which means they are related to sea urchins, sand dollars, basket stars, brittle stars, and sea cucumbers. All echinoderms have a calcareous skeleton covered with skin. They also usually have spines.

The Difference Between Sea Stars and Brittle Stars This round, specialized plate allows water to enter the water vascular system. In sea stars, it's located on the "top" (or aboral, meaning opposite of the side of the mouth). In brittle stars, it's located on the "bottom" (or oral side). But, let's be honest—it's way easier to tell them apart by looking at their arms (see above). There you have it!
