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.
Organisms that reproduce asexually include bacteria, some plants, and fungi like yeast. Organisms that reproduce sexually include humans, animals, and many plants. Some organisms have the ability to reproduce through both sexual and asexual means, like certain types of jellyfish.
There are tons of organisms that reproduce asexually. As for ANIMALS - A lot of species of fish do (some sharks partake in parthenogenesis - a type of asexual reproduction), some species of wasps, whiptail lizards, sea anemones, coral, starfish, snails. All fungi, bacteria, Archaea, Protist and amoebas reproduce asexually. Some plants are capable of reproducing asexually, such as strawberry, onions and potatoes.
There are a few forms of life on Earth that reproduce by the act of "budding". A lot of sea life, such as coral, reproduce by spreading spores from buds into the ocean, while a lot of plant life, like blueberry plants, reproduce by budding fruit that is eaten and spread by animals.
Bacteria (by fission), some plants (by budding), and some sea life such as sea stars (regeneration- when a sea star is torn apart let's say into a 4-piece part and a 1-piece part, they both start to regenerate other arms to make 2 sea stars each with the normal 5 arms.). This is true. If you don't believe me consider this: I get an A+ in Science. If you still don't believe me, check a Science Textbook. Hope this helped! :)-Anonymous Source
It sounds like you might be describing a coconut. Coconuts grow on palm trees and have a hard, spherical outer shell with a hairy appearance that can resemble a sea urchin. Inside the shell is the edible white coconut meat and coconut water.
They reproduce asexually and sexually.
sometimes, when they see a full moon
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.
Sea urchins generally have separate sexes and spawn seasonally every year. Eggs and sperm are usually released to the water column where fertilisation occurs.
Sponges can reproduce sexually or asexually
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 Stars reproduce both asexually and sexually.
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.
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.
They can do both! A strategy that has evolved in some sea stars and brittle stars is the ability to reproduce asexually by dividing in two halves while they are small juveniles, while turning to sexual reproduction when they have reached sexual maturity.
Many species of reptiles, amphibians, and some invertebrates, such as certain types of jellyfish and sea stars, can reproduce both asexually and sexually. For instance, some lizards can reproduce asexually through parthenogenesis, while others utilize sexual reproduction. Similarly, many species of sponges and corals can reproduce through budding or fragmentation (asexual methods) as well as through gamete fusion (sexual reproduction). This dual reproductive strategy allows these animals to adapt to varying environmental conditions.
by mating with another GIANT red sea urchin!
