Sea urchins primarily reproduce sexually; they release eggs and sperm into the water for external fertilization. However, some species can also reproduce asexually through fragmentation, where a part of the sea urchin can grow into a new individual. Overall, sexual reproduction is the most common method for sea urchins.
Sea urchins primarily reproduce sexually, with most species engaging in external fertilization. During spawning, they release eggs and sperm into the water, where fertilization occurs. Some species can also reproduce asexually through regenerative processes, but sexual reproduction is the dominant method for population growth.
They reproduce asexually and sexually.
Sea urchins generally have separate sexes and spawn seasonally every year. Eggs and sperm are usually released to the water column where fertilisation occurs.
They reproduce Asexually
Sea Stars reproduce both asexually and sexually.
Sponges can reproduce sexually or asexually
According to the book Laboratory and Field Investigation in Marine Life they reproduce through broadcast spawning, which is realizing a bunch of sperm and eggs into the water with the chance of one becoming fertilized.

Sea urchins reproduce sexually, with separate male and female individuals releasing eggs and sperm into the water for fertilization to occur externally. They can also reproduce asexually through a process called fragmentation, where a piece of the sea urchin's body can regenerate into a new individual.
Sea urchins reproduce by releasing eggs and sperm into the water, where external fertilization takes place. Once fertilized, the eggs develop into larvae that eventually settle and grow into adult sea urchins. Some species of sea urchins can also reproduce by asexual means, such as splitting or budding.
The sea archin releses sperm and eggs in to the water the eggs then get firtilised
