Enderbury Island Island of Kiribati in the Pacific Ocean

Enderbury Island, also known as Ederbury Island or Guano Island, is a small, uninhabited atoll 63 km ESE of Kanton Island in the Pacific Ocean at 3°08′S171°05′W. It is about 1 mile (1.6 km) wide and 3 miles (4.8 km) long, with a reef stretching out 60–200 metres. Forming a part of the Canton and Enderbury Islands condominium from 1939 to 1979, the island is now a possession of the Republic of Kiribati.

Orona Pacific island of Kiribati

Orona atoll, also known as Hull Island, is one of the Phoenix Islands in the Republic of Kiribati. It measures approximately 8.8 km (5 mi) by 4 km (2 mi), and like Kanton, is a narrow ribbon of land surrounding a sizable lagoon with depths of 15–20 metres (49–66 ft). Numerous passages connect the lagoon to the surrounding ocean, only a couple of which will admit even a small boat. Total land area is 3.9 km2 (2 sq mi), and the maximum elevation is nine metres.

Holothuriida Clade of sea cucumbers

Holothuriida is an order of sea cucumbers. Taxa within the order Holothuriida were previously classified in the order Aspidochirotida, which was determined to be polyphyletic in 2017. Some taxa were also reclassified into the clades Synallactida and Persiculida.

Microatoll

A microatoll is a circular colony of coral, dead on the top but living around the perimeter. Growth is mainly lateral, as upward growth is limited by exposure to air. Microatolls may be up to 6 meters (20 ft) in diameter. They are named for their resemblance to island atolls formed during the subsidence of volcanic islands, as originally suggested by Darwin (1842).

Wakatobi National Park Marine park in Southeast Sulawesi, Indonesia

In August 2018, the IUCN Red List of Threatened Species identified 6086 Vulnerable species, subspecies and varieties, stocks and sub-populations in the Animalia kingdom.
