Starfish also notice the signals of other starfish who are ready to reproduce and they gather in large groups at this time. For a creature without brains or blood, they are pretty interesting as well as beautiful. Except when they turn their stomachs outside their body to catch their prey....
Starfish have evolved to fit their environment by developing various specialized feeding habits. Most starfish are carnivorous hunters that prey on specific animal species such as mussels, clams, oysters and sea snails. They locate their quarry with light-sensing eyespots at their arm tips, then pr...
Organisms that eat meat or other animals as the main part of their diet are called herbivores. True | False 5. The stomach of a starfish surrounds the edible parts of their prey and digests it. True | False 6. The seven digestive glands of a starfish specialize in breaking down and...

Describe the similarities and differences in the embryonic development of starfish and frogs. What characteristics of protozoa make them resemble animals? With which animal(s) do we share a very fundamental architecture of the brain? What are at least three animal structures that would be analogous...
Sea anemones might look like plants at first. But, these creatures are actually animals. They live a sedentary life, but are active hunters. They use powerful stinging cells on their tentacles to capture any small prey that drifts by, such as fish, crustaceans and plankton....
from freshwater ecosystems, as their waters are salty in nature. Marine habitats are quite unique because they harbor a wide variety of life forms, including birds, mammals, insects, fish andbacteria. Some well-known species that live in these habitats are whales, dolphins, starfish and corals....
4. Reduced space on the substratum. Tide pools will almost always have water in them, although it may be lower than usual. This makes it an ideal location for organisms that are sedentary and often fixed to the substratum. Starfish, sea sponges, and sea anemones attach themselves to the ...
What roles do sponges and starfish play in their ecosystems? Sponges filter water and provide habitats, whereas starfish are important predators that help control the population of their prey. 14 What is a sponge? A sponge is a simple marine organism that filters nutrients from water passing thro...
