“Save Our Shores, Save Our Ocean” – Series III (Definitive Issues)

To send the message on the importance of taking care of our natural resources and in the context of environmental and health crises caused by exploitation, PHLPost issues “Save Our Shores, Save Our Oceans”  with photographs provided by the National Museum of the Philippines and images of Philippine waters from FUNtastic Philippines, Inc.

Martini's tibia (Rostellariella martinii).  A species of sea snail, a marine gastropod mollusk in the family Rostellariidae within the Stromboidea, the true conchs and their allies.  Most specimens are found in the Philippines from tangle net fishing, although  strangely,  it is in the Philippines protected species list.  It was in the 50 rare shells but,  it is hardly rare as it is a deep water species like most of the species in the genus. There are two forms known, a lighter, smaller shell and a larger, thicker shelled form. 

Yoka star turban (Guildfordia yoka).  A species of deep-water sea snail, a  marine gastropod mollusk in the family Turbinidae, the turban snails.  The size of the shell varies between 2.8 and 4.1 inches. The color pattern of the shell varies from very light brownish to purple-brown. Some specimens contain only six whorls instead of seven as in the holotype. The upper whorls are smooth.  The base of the shell is less convex than the upper part. Some specimens lack the rose-colored line around the umbilical callosity.

Both attractive specimens of marine wildlife, these gastropods are bought and sold for their aesthetics. To protect local populations, the catching and exporting of R. martinii has been forbidden by law (Fisheries Administrative Order no. 208, s. 2001).
