Purple-crowned Sea Goddess – Felimare kempfi

The Purple-crowned Sea Goddess ( Felimare kempfi) is a captivating species of sea slug, showcasing the vibrant colors and intriguing forms characteristic of nudibranchs. Its stunning appearance and fascinating life cycle make it a popular subject for marine biologists and underwater photographers alike.

Description & Characteristics

The Felimare kempfi is a medium-sized nudibranch, reaching a maximum length of approximately 5 cm. Its body is typically elongated and slender, with a distinct head and a pair of prominent rhinophores, or sensory organs, atop its head. The most striking feature of the Felimare kempfi is its vibrant coloration. Its body is typically a deep purple or blue, with a bright yellow or orange crown-like marking around its head. This crown is often surrounded by a thin white line, further enhancing its striking appearance.

Habitat and Occurrence

The Felimare kempfi is a subtidal species, primarily inhabiting the sublittoral, infralittoral, and deep zones of the oceans. Its range extends from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. This makes it a common sight in neritic marine ecosystems, where it can be found clinging to rocky surfaces and coral reefs.

Taxonomy

The Felimare kempfi is classified within the Class: Gastropoda, the largest and most diverse class of mollusks. It belongs to the Order: Nudibranchia, a group known for their external gills and lack of a shell. The Felimare kempfi is a member of the Family: Chromodorididae, a family renowned for their brilliant colors and often intricate patterns.

Feeding

The Felimare kempfi is a specialist feeder, relying on sponges as its primary food source. It uses its radula, a tongue-like structure with rows of teeth, to scrape the sponge’s tissue and consume its flesh. Interestingly, the Felimare kempfi can incorporate the sponge’s toxins into its own body, providing a form of chemical defense against predators. This unique adaptation allows it to thrive in its diverse and sometimes challenging environment.
