Petaloconchus keenae is a worm snail  ooperculum shelled gastropod common commonly native in '''Central Pacific waters of Hawaii, Guam, and Japan. P. keenae and the coral Porites share a heavy symbiotic relationship which allows a distribution range to extend further to the subtidal zone from the intertidal zone. ''' intertidal and subtidal areas in Hawaiʻi and the tropical Pacific. '''They are members of the Vermentidae family, known for their irregular shell shapes.  Their reproduction cycle is continuous and develops poecilogonally. ' has a symbiotic relationship with multiple coral genera, such as Porites, Montipora, and Pavona''. 'The process of feeding for P. keenae'' is accomplished by two collections processes either by mucous nets or ctenidial cilia. '''

Shell Structure
'P. keenae'' shells are based on hard surfaces, especially that of various species of corals, most commonly the Porites coral. The shell is a lightly sculptured operculum, apertures extend upward from the center,forming a tube up to 50mm in legnth and opening of 5mm in diameter. '''

Shell Color
'The mantled edges of the P. keenae'' are yellow while having two variations of main coloring that are either different hues of brown, or purple with white markings. '''

Shell Texture
'P. keenae'' also shows variations in the textures of the shells that they form. Typically an adult shell will coil smoothly leaving the texture of the shell smooth, while other times an adult shell will have coils of that are different in tube size, coils size, coil placement, and coil direction, this will give an adult P. keenae with a rigid and rocky looking shell. '''

Zonation
'P. keenae'' are found in the interidal and subtidal zones in the tropical waters of the Central Pacific waters. They occur as native organisms to Guam, Hawaii, and Japan. Their permanent placements allow them to have strong relationships to the substrate and therefore can be found commonly in benthic substrates. '''

Porites Coral
'P. keenae'' have a strong symbiotic relationship to the corals within the Porites family that are characterized by their hard and stone like surface. It is because of their relation to these specific corals that allows for the distribution of P. keenae to extend deeper into the subtidal zone. '''

Mating Seasons
==== P. keenae '''has a reproductive season that is continuous throughout the year. Althought reproduction rates suring the summer months are low. ''' ====

Methods
==== '''Their reproduction method is a shell brooding pattern where males release sperm into the water to land in the shell of a female. P. keenae use poecilognony as a reproductive stragegy. This is where they produce a mixture of hatching juveniles and and short-term veligers. The size of their larva or juveniles are dependent on the availability of nutrients in the yolks they nurse on versus the sizes of their eggs. Eggs have a diameter of 0.217 mm. Sizes of the indirect hatching size of veligers is 0.29 x 0.39 mm, and the sizes for the mixed juveniles or veligers have a hatching size of 660x450 um. ''' ====

Feeding
'P. Keeane'' have a predominate ciliary which they use in the collection of detrital by ctenidal cilia as one of their feeding processes. They also accomplish this by using mucous nets to catch their food. '''
