They spend most of their life alone but congregate occasionally in larger groups during certain times of the year to feed or mate. Starfish capture oxygen from the water meaning if they are out of water they can die in short time since they cannot perform gas exchange.

Do starfish live in groups?
Sea stars aren't social creatures, but they will congregate in large groups during certain times of the year to feed.
Why do starfish gather?
Starfish tend to feed on mollusks, whose beds are typically in shallow water. Millions of starfish will congregate around mussel beds at any time, and when strong currents pass through these habitats during a storm, starfish can be lifted away from their meal and carried to the shore.
What is a starfish group?
sea star, also called starfish, any marine invertebrate of the class Asteroidea (phylum Echinodermata) having rays, or arms, surrounding an indistinct central disk. Despite their older common name, they are not fishes.
What is special about starfish?
Starfish, also known as Sea Stars, are one of the most beautiful looking animals in the vast ocean. They have a surprisingly unusual anatomy, with no brain or blood, yet are able to digest food outside their body. Regenerating their own arms is perhaps one of the most useful things a starfish can do.
How do starfish have babies?
NARRATOR: Some starfishes reproduce by releasing their eggs directly into seawater. About the time the eggs are released by female sea stars, males release their sperm. ... Eventually they develop into larvae, which in time return to the seafloor and become starfishes.
What would happen to the starfish population give a reason for your answer?
Answer: In the absence of the no of shellfish the population of the starfish will decrease and the population of the seaweed will increase . In other words the whole aquatic food chain will get disturbed.
Why do starfish come to shore?
As water currents become stronger, they are pushed onto the beaches. While the starfish may appear to be stranded, they also have the ability to return to the water when they've been exposed for too long, so touching them is not recommended.
What would happen to the starfish population?
Star fishes know as sea stars are invertebrate carnivorous aquatic animals live in salt water. ... If the shell fish dies, the populations of star fish would decrease dramatically. Although, starfish is a slow moving animal, so it can attack on those animals which are faster that it.
How does a starfish see?
So how do they see? While it may not look like starfish have eyes, they do, although they're not like our eyes. A starfish has eyespots that cannot see much in the way of details but can detect light and dark. These eyespots are at the tip of each of the starfish's arms.
How many hearts does a starfish have?
02Starfish does have a brain. 03They also don't have blood and a heart. 04Instead of blood, they have a water vascular system. That system pumps seawater through the tube feet and throughout the starfish's body.
How do starfish survive?
Instead of blood, starfish have a seawater vascular system that circulates nutrients and powers their tube feet, allowing them to move about their environment. Starfish produce and expel huge amounts of eggs and sperm into the water giving them a better chance of survival.
Where does a starfish live?
Sea stars live in salt water and are found in all of the world's oceans, from warm, tropical waters to the cold seafloor. Sea stars are mostly carnivorous and prey on mollusks—including clams, mussels and oysters—which they pry open with their suction-cupped feet.
What are starfish kids?
Starfish are star-shaped, but they are not fish. They are invertebrates (animals without backbones) that live in the sea. Although these creatures cannot swim, they are very good at crawling and can walk up strands of seaweed and climb down the sides of rocks.
How would you describe a starfish?
Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.
