How do star fish mate?

Answer 1

Starfish species have various forms of reproduction, some sexually and some asexually. Of those that reproduce sexually, the gametes are released into the water to merge. Only one species has been found that internally "incubates" its spawn in its stomach. Some starfish begin life as males and later become female.

The fact that starfish can regenerate lost arms, and that some reproduce by division, has confusing repercussions. Many sources parrot outdated information that starfish that are chopped into arms (or arms that have some part of the central disc) can create an entirely new starfish. This is apparently supposition, as the cells for a complete individual are not present in all parts of the starfish. Only in some species does a starfish provide for autonomous survival of segregated limbs (reproduction by division).

Answer 2

Starfish commonly reproduce via a method called "free-spawning". This means that they release their gametes (A reproductive cell that has a haploid number of chromosomes, normally a mature sperm or egg that is capable of fusing with a gamete of the opposite gender to create a fertilized egg) into the water, where they will hopefully be fertilized by the gamete from the opposite sex. It is thought that to increase the chances of fertilization, starfish will gather in groups when they are ready to spawn, using environmental signals to coordinate their timing, and chemical signals to indicate their readiness to each sperm.

Answer 3

For most species... a male and a female in an aquarium, and hope for the best. They're mostly spawners - each releases the necessary 'stuff' into the environment.

A few species also use separation to reproduce asexually.

Answer 4

they mate by fragamation it is an Asexual reproducing. it where only one parent is regierd. fagrmation is where the star fish loss an arm a9like being eaten by an otter and the otter drops an arm) and another star fish grows from the arm.

Answer 5

Some starfish reproduce with eggs and sperm (sometimes coming from the same starfish), while others can split in half.

Answer 6

They lay eggs in the sand.

Answer 7

yes they do of course. They lay eggs
