What organ of both fish and clam has the same function as the papulae of the starfish?
The organ in both fish and clams that serves a similar function to the papulae of starfish is the gills. Gills are responsible for gas exchange, allowing aquatic animals to absorb oxygen from the water and expel carbon dioxide. In starfish, papulae also facilitate gas exchange and help in excretion, functioning similarly to gills in terms of respiratory processes.
Functions in feeding and gas exchange within echinoderms such as the sea star?
In sea stars, the tube feet are used for feeding by capturing and manipulating prey. Gas exchange occurs through tube feet and papulae, which are small projections on the body surface that allow oxygen and carbon dioxide to diffuse in and out of the water vascular system. Water is circulated through the tube feet and papulae to facilitate gas exchange and nutrient uptake.
What phylum contains sea stars?
Includes: Sea Stars, Sea Lillies, Sea Urchins, Sea Cucumbers, Brittle Stars
What structures are scattered between the spines of a sea star on its dorsal surface?
On the dorsal surface of a sea star, structures known as "papulae" or "respiratory papulae" are scattered between the spines. These are soft, fleshy projections that aid in respiration and waste removal by facilitating gas exchange. Additionally, the surface may have small, calcareous plates called "ossicles" that provide support and protection. Together, these structures contribute to the sea star's overall physiology and environmental interaction.
What are facts about sea stars?
sea stars have NO brains
Are sea stars flexible?
sea stars are flexible. sea stars do not have any bones. so they are very flexible:)
Are sea stars the same as sea fish?
Sea stars are not fish so no, it is not.
What are the groups of echinoderms?
Sea stars, brittle stars, sea urchins, and sea cucumbers.
Do sea stars need food to survive?
Yes. Sea stars are carnivores that eat can eat other sea stars and shrimp and other crustations like crabs. Over a long period of time sea stars move across the ocean floor. Giant sea stars will sometimes specifically prey on other, smaller sea stars. they eat poop
Do sea stars mate?
Sea Stars reproduce both asexually and sexually.
What food do sea stars eat?
sea stars eat clams and oysters
What are sea stars prey?
sea stars prey are clams,oysters and mollusks
