The red sea urchin (Mesocentrotus franciscanus) is a sea urchin found in the northeastern Pacific Ocean from Alaska to Baja California. It lives in shallow waters from the low-tide line to greater than 920 ft deep, and is typically found on rocky shores sheltered from extreme wave action in areas where kelp is available. Strongylocentrotus franciscanus.

This is a close-up photo of a pink Mushroom Corals (Fungiidae sp.). It showcases the beautiful details and texture of the coral and its tentacles. The colony was discovered and photographed in its natural condition on the reef within the lagoon of Majuro Atoll, located in the Marshall Islands, Pacific Ocean.
A vibrant purple sea urchin, scientifically known as Strongylocentrotus purpuratus, is embedded in a rocky crevice on the ocean floor. Its long, needle-like spines extend outward, creating a spiky silhouette against the brownish rocks and yellowish-green seaweed. Bubbles and subtle water currents suggest a submerged marine habitat. The image captures the intricate details of marine life in a natural underwater setting, ideal for commercial uses such as educational materials on ocean ecosystems, marine biology textbooks, environmental documentaries, aquarium promotional content, and articles on sea creature conservation. The close-up view highlights the texture and color contrast, suitable for stock imagery in travel magazines focusing on underwater exploration or scientific publications illustrating biodiversity in coastal waters.

Tubifer Cardinalfish Siphamia tubifer (ex. Siphamia versicolor) occurs in the tropical Indo-West Pacific from the Red Sea south to Madagascar and east through the Maldives, Sri Lanka and India to the Andaman Sea Islands and to Western Australia, north to the Ryukyus andthroughout the Indo-Malayan region to Vanuatu in a depth range from 1 to 100m, usually to 18m depth, max. length 7cm. \nThe species forms small groups with long-spined urchins, but is also found among the spines of Acanthaster planci. Siphamia tubifer feeds on zooplankton and small invertebrates. The specimen encountered in this Blue Spotted Sea Urchin Astropyga radiata is dark brown. Depending on the phase the species can be striped instead.\nBlue Spotted Sea Urchin Astropyga radiata occurs in the tropical Indo-Pacific Ocean from the African coast to Australia and to Hawaii in a depth range from 0 to 60m, usually 10 to 30m, max. test diameter 20cm. \nThe species is often found in lagoons and bays where the substrate is sand, shingle or coral rubble. Sometimes many urchins collect together in one locality in dense aggregations. \nLembeh Strait, North Sulawesi, Indonesia \n1°28'47.814 N 125°15'1.26 E at 23m depth
