Sea urchins are primarily found in the benthic zone of the ocean, which includes the ocean floor and the areas just above it, typically at depths ranging from shallow coastal waters to depths of about 1,000 meters. They are often associated with rocky substrates, coral reefs, and kelp forests, where they graze on algae and other organic material. Some species may inhabit deeper waters, but most thrive in shallow, temperate, and tropical marine environments.
Echinoderms are marine animals, which means they reside in the ocean. Echinoderms are found from the intertidal zone to the abyssal zone.
* Aphotic Zone
The hadal zone, found in the deep trenches of the ocean floor, is considered the darkest ocean zone. This zone can reach depths of over 6 miles (10 kilometers) and is characterized by extreme pressure, cold temperatures, and a lack of sunlight.
artic zone
Clown fish live on the continental shelf part of the ocean zone.
Coastal Ocean
Kelp forests are found in the ocean zone called the neritic zone, which is the shallow part of the ocean where sunlight can penetrate to allow for photosynthesis. These underwater ecosystems are typically located in temperate and polar regions with nutrient-rich waters.
Sea sponges are a part of the marine biome. They are even found in the disphotic zone of the ocean, also known as the Twilight Zone.
The benthic zone is a region at the lowest level of an ocean or lake. The intertidal zone is the shallowest part of the benthic zone.
The neritic zone is the relatively shallow part of the ocean above the drop off of the continental shelf. The neritic zone is also known as the coastal water, coastal ocean or the sublittoral zone.
