The branch coral (Acropora florida) is a species of acroporid coral found in the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan and the East China Sea, Cook Islands and the oceanic west Pacific Ocean. It can be found in shallow reefs on the reef tops, walls and slopes to depths of 30 m.

Description

Colonies of Acropora florida consist of thick upright, and sometimes horizontal, branches growing from a sprawling or encrusting base. There are side branches and small branchlets which resemble knobs. The corallites are evenly spread. The colour of this coral varies, and may be pinkish-brown or some shade of green.[2]

Biology

Acropora florida is a zooxanthellate species of coral.[2] It obtains most of its nutritional needs from the symbiotic dinoflagellates that live inside its soft tissues. These photosynthetic organisms provide the coral with organic carbon and nitrogen, sometimes providing up to 90% of their host's energy needs for metabolism and growth. Its remaining needs are met by the planktonic organisms caught by the tentacles of the polyps.[3]

Status

This coral is a common species and no species-specific threats have been identified. The main threats faced by corals in general are related to climate change and the mechanical destruction of their coral reef habitats; increasing damage from extreme weather events, rising sea water temperatures and ocean acidification. The International Union for Conservation of Nature has assessed the conservation status of this species as being "near threatened". All corals receive protection by being listed on CITES Appendix II.[1]

gollark: Undoubtedly.

gollark: One time the exploit was released in an obfuscated bytecodey form, but they left the debugging symbols in, so I could just run it through a decompiler. Fun times.

gollark: I've had to reverse engineer obfuscated potatOS exploit programs fairly often.
