Echinoderms, a group that includes starfish, sea urchins, and sea cucumbers, exhibit a range of mobility. While many species, like sea stars, can move slowly using tube feet, others, such as sea cucumbers, can be more sedentary but are not completely sessile. Some echinoderms, like certain sea lilies, are largely attached to the substrate and display a sessile lifestyle. Overall, echinoderms can be both mobile and, to a lesser extent, sessile, depending on the species.

What are sessile echinoderms?
sea lilies
Are roundworms sessile or mobile?
they are sessile
How do the feedings hibits of sessile echinoderms differ from those that are mobile?
Sessile echinoderms, such as sea cucumbers and sea lilies, typically feed by filtering particles from the water or using their tube feet to capture food, relying on water currents for nutrient delivery. In contrast, mobile echinoderms, like starfish and sea urchins, actively seek out food sources, often preying on other organisms or grazing on algae. This difference in feeding habits reflects their adaptations to their respective lifestyles, with sessile species being more reliant on passive feeding mechanisms, while mobile species exhibit more active foraging behaviors.
What are 3 the difference between mobile and sessile?
well all i know is sessile you stay in the same place and mobile you can live many places
Is plantae mobile or sessile?
All Cnidarians are mobile at some point in their lifetime. For most, it is in the larval stage. Jellyfish start out as mobile larva, then become sessile, then become the mobile jellyfish you are familiar with. Others, like corals, start out as mobile larva, settle down and remain sessile for the rest of their adult life. As adults, hydra can be mobile or sessile, as they choose, but they don't swim far.
Are sea urchins sessile?
Yes. Classes of mollusks which include clams, oysters, and other bivalves are sessile filter feeders.
Do some echinoderms live attached to rocks?
Yes, several. Most crinoids are sessile and live their life attached to underwater rocks, as do several starfish species.
What is a crustaceans that are sessile as adults?
Barnacles are sessile as adults. They start out as mobile larvae and attach to something big like a whale or a boat. Then they stay in this position for the rest of their lives.
An animal that can move freely around in its environment is called?
mobile, the opposite (antonym) is sessile.
Are feather stars sessile?
An adult feather star is not sessile. It eventually develops arms and is able to move around. Sea lilies are sessile.
Is hydra sessile or non sessile?
a hydra as a polyp is not sessile but when it grows to be a hydra it is sessile
What is benthic sessile?
Benthic sessile organisms are marine organisms that live on the ocean floor and remain attached to a substrate, such as rocks or coral. They do not move around like mobile organisms but instead filter feed or rely on currents to bring them food. Examples of benthic sessile organisms include sponges, corals, and mussels.
