Ostranka Růžová

Overview

Chicoreus palmarosae, commonly known as the rose-branch murex, is a predatory marine gastropod in the family Muricidae. This ornate sea snail is widely recognized for its highly sculptured shell and distinctive, frond-like spines that often feature delicate pink tips.

Appearance

The shell of an adult rose-branch murex typically measures between 65 mm and 130 mm in length. Its exterior is characterized by complex, branch-like structures and alternating stripes of brown and tan, while the inner surface is notably smooth. The species exhibits significant morphological variation across its range; for instance, populations in the Philippines may display reduced spine development compared to those found elsewhere.

Distribution & habitat

This species is widely distributed throughout the Indo-Pacific, ranging from the Indian Ocean—including the Chagos Atoll, the Mascarene Basin, and Sri Lanka—to the Pacific Ocean, reaching as far as southern Japan. It is primarily a reef-associated species, typically observed on or near coral reefs and sand or mud flats. When its spines become coated with sea moss or debris, the snail can be effectively camouflaged against its rocky or reef environment.
