We went on a mini exploration at the North Point harbour to see what biodiversity was there.
List of species which we found.
Perna viridis- known as the Asian green mussel

Tetraclita japonica- common barnacle species in Hong Kong
The Oddities on the Rock (II) It is easy to find some small volcanoes at the pier or rocks on shores. Actually, these volcanoes are barnacles, a common organism in the intertidal zone. Though it is often misjudged as "clams" owing to their appearance, it belongs to the class Crustacea, the same class as crabs and shrimps.
Episesarma versicolor- small local crab species
Episesarma versicolor - Wikipedia
The violet vinegar crab ( Episesarma versicolor) is a swimming crab species in the genus Episesarma . Distributed all over marine and brackish waters of Indo-West Pacific regions. It is harvested by many local fishermen for rich proteinaceous food.
Saccostrea cucullata- a local species of oyster
Asiatic hard clam
For the four other clam species below, WWF has designated the minimum size for capture to be 30 mm (or 3 cm). This can be applied to other clam-digging hotspots other than Shui Hau. To manage clam resources, overseas regulatory authorities have implemented fishery plans to control clamming activity.
Ylistrum japonicum- a local species of scallop

From Wikipedia, the free encyclopedia Jump to navigation Jump to search Ylistrum japonicum , known as saucer scallop is found around the waters of Japan, Philippines, south eastern Asia and Australia. Well regarded as seafood in Asia and Australia.
Commercially important mussels belong to the family Mytilidae and are predominantly marine (see Table 1). Freshwater mussels involved in pearl production belong to the Order Unionida. Commercial Mytilid species come from wild harvest fisheries (global production of 237 823 tonnes in 1999) and a greater proportion from aquaculture (1 451 032 tonnes in 1999).
Mopalia muscosa - Wikipedia
This species is found in the middle and lower intertidal zone on exposed rocky shores. Mopalia muscosa can be 40 to 55 mm (1.6 to 2.2 in) in length. In life it is quite often covered with growths of algae such that it is difficult or impossible to really see the plates.
What is a sponge?
Sponges are animals with dense skeletons that are highly adapted to their environments, although it is easy to see why they may be mistaken for plants. Sponges are found in a wide variety of colors, shapes, and sizes - and scientists believe that the colors of the sponge may act as a protection from the sun's harmful UV rays.
Periwinkle | marine snail
Periwinkle, in zoology, any small marine snail belonging to the family Littorinidae (class Gastropoda, phylum Mollusca). Periwinkles are widely distributed shore (littoral) snails, chiefly herbivorous, usually found on rocks, stones, or pilings between high- and low-tide marks; a few are found on
