White spots on a starfish usually indicate illness. If the salinity in your tank has changed, it can cause the starfish to become ill and may even be fatal.
35 parts per thousand, or a specific gravity of 1.025, approximately.
No, starfish should not be put in tap water with salt. Starfish are marine animals and require a specific salinity level to survive. Putting them in tap water with salt can disrupt their internal balance and harm them. It is best to keep starfish in a saltwater tank that mimics their natural environment.
A starfish typically requires a tank of at least 20 gallons to thrive, as they need ample space to move and explore. It's important to ensure the tank has stable water conditions, as starfish are sensitive to changes in salinity and temperature. Additionally, a well-maintained tank with plenty of hiding spots and live rock is beneficial for their health. Always research the specific species of starfish you plan to keep, as their needs can vary.
Salinity is a noun.
there are cusion starfish, reef starfish, spiny starfish and fire brick starfish in new zealand.
It is called toilet water.
Starfish maintain homeostasis primarily through their water vascular system, which helps regulate internal pressure and facilitates movement and feeding. They rely on a network of canals filled with seawater to control their tube feet, enabling them to adapt to changes in their environment. Additionally, starfish can regulate their internal salt concentration by selectively absorbing or expelling water through their tube feet and body surface, helping them balance their osmotic pressure in varying salinity levels.
Salinity is a measure of the saltiness of water.
Yes they can
Sure, starfish larvae are planktonic. Adult starfish are not.
seeing as starfish live in most, if not all levels of the sea, any plant you can think of as being a marine plant lives where starfish live. Examples: phytoplankton, red algaes, green algaes, brown algaes, sea grasses.
