The Sera Anemone – Arachnanthus lilith is a captivating marine invertebrate known for its striking appearance and unique characteristics. This anemone is an azooxanthellate species, meaning it does not rely on symbiotic algae for sustenance. Instead, it obtains nutrients through its diet of zooplankton.
Description & Characteristics
The Arachnanthus lilith showcases a distinct morphology, with a slender, cylindrical body and a crown of long, delicate tentacles. Its vibrant color palette often includes shades of orange, red, and purple. The anemone’s tentacles are adorned with numerous stinging nematocysts, which it uses to capture prey. The size of this anemone varies, reaching a maximum length of around 10 cm. Its depth range extends from shallow to deep waters, with the Arachnanthus lilith commonly inhabiting the mesophotic zone.
Habitat and Occurrence
The Sera Anemone – Arachnanthus lilith thrives in a variety of marine environments. It is a common sight in the tropical and subtropical regions of the Indo-Pacific Ocean. This species is often found attached to rocky outcrops, coral reefs, and seagrass meadows. Its presence is most notable in the epipelagic and mesopelagic zones, where it benefits from the abundant food sources present in these depths.
Taxonomy
The Arachnanthus lilith belongs to the Class: Hexacorallia, Order: Ceriantharia, and Family: Arachnactidae. This classification places it among a group of diverse and fascinating marine invertebrates that are characterized by their unique body structures and symbiotic relationships with other organisms.
Feeding
As an azooxanthellate species, the Arachnanthus lilith relies on a carnivorous diet. Its primary food source consists of zooplankton, small crustaceans, and other microscopic organisms. The anemone’s tentacles are equipped with stinging nematocysts that paralyze its prey, allowing it to be efficiently consumed.
