Sure, starfish larvae are planktonic. Adult starfish are not.
Starfish undergo external development. Fertilization usually occurs externally in the water, and the larvae develop outside the adult's body before settling down and metamorphosing into the adult form.
Starfish reproduce externally by releasing eggs and sperm into the water where fertilization occurs. The fertilized eggs develop into larvae which are released into the water. The larvae eventually settle on the ocean floor and develop into adult starfish.
Yes; jellyfishes can eat starfishes plutei (larvae).
Baby starfish, or larvae, do not stay with their parents after birth. They are released into the water, where they drift and develop independently. Starfish have a planktonic stage before settling down and transforming into juvenile starfish, at which point they begin their life on the ocean floor. Parental care is not a part of their reproductive strategy.
Plankton are a diverse group of organisms that flow with the ocean currents. They include drifting or floating bacteria, archaea, algae, protozoa, jellyfish, copepods, salps, sea urchin larvae, starfish larvae, and fish larvae.
The earliest known Echinoderm is from the Vendian period 560 million years ago. Starfish branched off sometime after this, possibly in the Ordovician.
Starfish typically mate during the spring and summer months when water temperatures are warmer. This allows for optimal conditions for reproduction and the development of their larvae.
The free-swimming larvae can travel much greater distances than the bottom-dwelling adults, increasing their range. If the environmental conditions for the adults become bad, the larvae can travel to another area that may be more favorable.
Before Coldplay's name was Coldplay it was''Starfish". And before it was Starfish, they were (without Will Champion on drums) Big Fat Noises and Trombelese.
Starfish larvae drift away to become part of huge swarms of plankton and fend for themselves. There's no parental care. ^^
They eat mostly mosquito larvae, THEY DO NOT ABSORB THEIR ENERGY FROM THE SUN! - to the goon who answered before me.
