Robillard'S Dendronotid
dendronotus robilliardi
Robillard's Dendronotid is a stunning marine gastropod that inhabits cold-temperate marine waters. Like other members of the Dendronotidae family, this nudibranch is characterized by its magnificent, branching dorsal appendages, which resemble miniature underwater forests. These appendages, called cerata, not only assist in respiration but also mimic the hydroids upon which the animal feeds, offering superb crypsis. Observant divers and tidepoolers are often spellbound by the delicate, translucent bodies of these sea slugs as they slowly navigate rocky substrates. Their presence is a great indicator of a healthy, diverse benthic ecosystem rich in colonial cnidarians.
Hábitat: Typically found in cold-temperate intertidal and subtidal rocky reefs, often clinging to bryozoan mats and colonial hydroids.
Aspecto
This species is a small nudibranch, typically reaching lengths between 1 to 5 centimeters. Its body is translucent white, sometimes flushed with pale orange, pink, or yellow undertones. It is adorned with branching cerata along its back, which have tipped variations of opaque white or golden yellow. Bright orange or reddish-brown speckles are often dotted across its body, and its highly branched rhinophores (sensory tentacles) protrude elegantly from the head, creating a complex, frilly silhouette that blends seamlessly into marine turf.

Datos interesantes
Its highly branched rhinophores function as chemical receptors, allowing the nudibranch to 'smell' food and mates in the water column.
Like many nudibranchs, it is a simultaneous hermaphrodite, possessing both male and female reproductive organs to maximize mating opportunities.
The elegant branching structures on its back act as gills, maximizing surface area for oxygen absorption directly from the seawater.
Habilidades especiales
Habilidad
Arborescent Crypsis
Its highly branched body appendages perfectly mimic the hydroid colonies it lives on, making it virtually invisible to visual predators.
Habilidad
Chemical Deterrence
It sequesters toxic or distasteful compounds from its cnidarian prey, rendering its own body unpalatable to potential predators.
Habilidad
Regenerative Cerata
If attacked, it can autotomize (shed) its branching cerata to distract a predator and later fully regenerate them without permanent damage.
