Dendrochirotida 
Pseudocolochirus axiologus Scientific classification Kingdom: Animalia Phylum: Echinodermata Class: Holothuroidea Subclass: Dendrochirotacea Order: Dendrochirotida Families (See Text)
Dendrochirotida are an order of sea cucumbers. Members of this order have branched tentacles and are suspension feeders. Examples are Thyonella and Cucumaria.
Characteristics
Holothurians in this order are characterised by ten to thirty much branched tentacles. They also have ring structures composed of ten calcareous plates circling the pharynx. The body wall is either firm with large ossicles or of a soft consistency with few ossicles. In some genera the animals attach themselves to hard surfaces but in others they burrow into soft sediments. Prey is captured by the sticky tentacles and transferred to the mouth. The larvae are lecithotrophic, not feeding on plankton but surviving only on materials already present in the eggs before settling and becoming juveniles.[1]
