The satellite is named Multispectral Unit for Land Assessment (MULA). [4] MULA would be the first of a "next-generation satellites" under the Philippine space program, with the team behind the satellite building on the knowledge gained in developing the Diwata and Maya nanosatellites. [5] The investment cost for the satellite is at least US$34 ...
A number of units of measurement were used in the Philippines to measure various quantities including mass, area, and capacity. The metric system has been compulsory in the country since 1860, during the late Spanish colonial period. [1] A mixture of Spanish units and indigenous units were used alongside American units in the 1900s.
[5]: 4–5 Aquaculture generally occurs in areas under local government (city and municipal) jurisdiction, which includes their land area and the sea up to 15 kilometres (9.3 mi) from their shoreline. Aquaculture infrastructure can be built on land, in inland waters, or in coastal and nearshore areas. [6]: 1
The mantle cavity is a central feature of molluscan biology. This cavity is formed by the mantle skirt, a double fold of mantle which encloses a water space. This space contains the mollusk's gills, anus, osphradium, nephridiopores, and gonopores. The mantle cavity functions as a respiratory chamber in most mollusks. In bivalves it is usually ...
Location of the Philippines. The non-marine mollusks of the Philippines are a part of the molluscan fauna of the Philippines (the wildlife of the Philippines). A number of species of non-marine mollusks are found in the wild in the Philippines.
Mantle of giant clam with light-sensitive spots, which detect danger and cause the clam to close. Tridacna gigas, the giant clam, is the best-known species of the giant clam genus Tridacna. Giant clams are the largest living bivalve molluscs. Several other species of "giant clam" in the genus Tridacna are often misidentified as Tridacna gigas.
Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as locomotion, feeding, respiration, and reproduction. The siphon is part of the mantle of the mollusc, and the water flow is directed to (or from) the mantle cavity. A single siphon occurs in some ...
This group includes land snails and land slugs. Loss of the shell has taken place many times in different groups that are not evolutionarily closely related, and land snails and slugs are most often treated together as a single group in specialized malacological literature. [2] [3] All terrestrial molluscs belong to the class Gastropoda.
