Anthopleura nigrescens, also referred to as the dusty anemone, is a sea anemone in the family Actinidae found in the Indo-Pacific.[1][2]
Description
The dusty anemone has a diameter of ¾ of an inch.[3] It has a grayish, dusty brown or black coloration, depending on the DNA configuration.[4]
Distribution & habitat
Anthopleura nigrescens is found in the Indo-Pacific. In parts of Hawaii and Costa Rica, this sea anemone is frequently observed in shallow water in tiny rocky cracks.[5] However, it has also been observed close to Taiwan's hydrothermal vents.[5]
Diet
Anthopleura nigrescens eat cyprids and copepods, which are a type of zooplankton; occasionally, they will eat prey such as gastropods, insects, eggs, and larvae.[6] Research has shown that their diet tends to change depending on the specific sight and depth of water.[7] The dusty anemone is a polyphagous predator.[6]
