Overview

Mycedium elephantotus is a widespread stony coral commonly known as the elephant nose or Chinese lettuce coral. It typically forms laminar or encrusting colonies that can reach significant sizes, often featuring a layered, fan-like structure.

Appearance

This species is characterized by its distinct, nose-shaped corallites that face outward toward the colony perimeter. The surface of the colony is marked by outwardly radiating ribs, and the corallites themselves can reach up to 15 millimeters in diameter. While colonies are often a uniform brown, grey, green, or pink, they may display vibrant, contrasting colors on their oral discs or margins. Some specimens exhibit iridescent qualities, which are particularly visible during the day.

Distribution & habitat

Found throughout the Indo-Pacific region, including the Red Sea and the Indian Ocean, this coral thrives in various reef environments. It prefers protected areas away from strong wave action and is frequently encountered on silty reef slopes, in caves, or along rock walls.

Biology & behavior

Mycedium elephantotus is a hermaphroditic broadcast spawner that follows an annual reproductive cycle. As a nocturnal feeder, it extends its tentacles primarily at night to capture passing plankton. During the day, the polyps remain retracted, highlighting the coral's unique skeletal architecture.
