How many sea urchins are their in the world?
It is difficult to estimate the exact number of sea urchins in the world due to various species and different habitats they occupy. However, sea urchin populations can vary greatly depending on factors such as environmental conditions and food availability.
What phylum do sea urchins belong?
Echinoderms.
Ho do sea urchins reproduce?
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.

Why did the populations of parrotfish and long spined sea urchins change the way it did?
The populations of parrotfish and long-spined sea urchins have changed primarily due to overfishing, habitat loss, and the impacts of climate change. Parrotfish are often targeted for their meat, leading to declines in their numbers, while long-spined sea urchins faced massive die-offs due to disease and environmental stressors. Additionally, the decline of coral reefs, which provide essential habitats, has further disrupted these species' populations. The changes in their populations can significantly affect coral reef ecosystems, as both play crucial roles in maintaining coral health and structure.
