To find food and avoid predators.
Brittle stars have long, flexible arms that help them move quickly, while basket stars have branched arms that are used for filter feeding. Brittle stars typically have five arms, while basket stars can have 10 or more arms that branch out extensively. Additionally, basket stars are usually found in deeper waters compared to brittle stars.
Brittle stars move by swaying their arms, or as they are called tentacles, side to side.Some smaller brittle stars "go with the flow" or move with the current because they are not strong enough to move by themselves or fight the current to go the way they want to go.
sea stars move through the water by emitting a fluid from the hole on their underside; it propels them through the water
Some brittle stars breed asexually. Most brittle stars are either male or female however some species are hermaphroditic.

The biggest threat for brittle stars is habitat destruction caused by activities such as bottom trawling, dredging, and pollution. These activities can disrupt their environment, destroy their food sources, and impact their ability to reproduce and thrive.
Yes, brittle stars are cold-blooded animals, meaning they cannot regulate their body temperature internally. Instead, they rely on external sources of heat to maintain their body temperature.
Brittle stars have predators such as larger fish, crabs, sea turtles, and some marine mammals. These predators feed on brittle stars by crushing or grabbing them with their strong jaws or claws. Brittle stars use their regenerative abilities to regrow lost limbs as a defense mechanism against predators.
Yes they do.
