Protect our coral reefs

Many people don't actually know that coral reefs are animals. They grow at a slow rate and are easy to break when they are kicked, trampled, or touched. Coral reefs are very sensitive to any human movement, so here, we ask you to pay attention to the creatures around you when swimming around the coral reef and not to destroy the marine ecology, and observe the following precautions:
· Please avoid contact with coral reefs Do not touch, kick, or stand on them.
· Please take away your garbage and reduce the use of plastic products to help us protect our islands and oceans.
· Please be careful when walking, and please rest only on the sand, not standing on coral reefs or seaweeds.
· When you are in the sea, please try to wear a life jacket or use a floating board, please do not stand on the coral reef.
· Coral reefs are sensitive and fragile. Newly born coral reefs are invisible to the naked eye, but even if you can’t see them, you can accidentally kill them when walking on the reef.
· Please pay attention to your fins when snorkeling and do not kick the sand on the coral reef.
· Feeding wild fish will destroy the balance of marine ecology. Please do not feed fish in the sea.
· Please do not chase marine creatures, and do not block their way.
· You can appreciate, but touching marine life may cause danger to organisms or humans.
· Please pay attention to the way in and out, and avoid walking through the seaweed. When sightseeing in the Piti Bomb Cave Reserve, please note that you can only enter and exit next to the sightseeing horse head.
· Please use sunscreen that is harmless to marine ecology and coral reefs.
· Please observe the relevant regulations of marine protected areas and fishing.
· Please note that it is illegal to take away coral reefs, shells, sand and other animals and plants in the ecological zone from the marine reserve.

· Achang Reef Marine Ecological Reserve in Maliso
· Patty Marine Reserve in Yigo



· Please pay attention and stay away from diving flags, and keep a safe distance of 60 meters from all swimming, snorkeling, and diving passengers.
· Since water waves generated by jet skis can accelerate the erosion of land, please stay away from the coastline and minimize the speed when you are near the coastline.
· Please stay away from coral reefs, seaweeds, and marine life.

watching. It is illegal to chase, harass, or possess any marine life. Please don't separate animals from their groups.

Do you know a little knowledge about Picasso triggerfish?
The mouth of Picasso triggerfish is naturally used to crush food, such as crustaceans, sea urchins, and other hard-shelled creatures, which are their favorites. They will build a home in the sand and have a strong regional character. Picasso triggers may become aggressive if you get too close, so please keep a safe distance in the water at all times.

Do you know a little knowledge about dolphins?
The most common dolphins in Guam are the long-nosed spinning dolphins, which are famous for their acrobatic performances. You can see them spin and leap out of the water, bringing wonderful performances to viewers. Long-nosed spinning dolphins often hunt with yellow flag tuna, so they are often affected by fishermen's fishing. The dolphin, also known as tuninos in the language of Chamorro, is an animal protected by federal law. Any chasing, feeding, touching, or harassment behavior is illegal. Please keep your distance and don't block their way, help us protect the wild marine ecology.

You know aboutLittle knowledge of Mañåhak?
The name of the original village of Maliso is Malesso', this name is derived from the Chamorro word lesso', and lesso' means the adolescent blue fish, also known as Mañåhak. This fish is a local delicacy and is very representative of Guam’s culture. The blue fish are locally known as mañahak runs along the upper reef beach each year. Fishermen use talaya nets to catch fish at this time every year.

Do you know a little knowledge about sea turtles?
Green turtles, also known as Hagaan, are very important to the Chamorro culture. The locals usually use Hagan on special days, and the Chamorro people also use Hagaan shells for jewelry. Their bones are also usually used to make tools. Green turtles are named after the color of their fat. People believe that the green turtle fat is green because they are herbivores. They love to eat seaweed and seaweed on the reef. Green turtles are currently endangered species, so any touching, chasing, harassing, or feeding behavior is illegal.

Do you know a little knowledge about corals?
Many people think that corals are stones or plants, but they are actually animals. Corals rely heavily on the small seaweeds that live in them, also known as zooxanthellae. Zooxanthellae provide coral food through photosynthesis, and corals protect them in return. When the temperature of the water becomes too warm, the corals may eject the zooxanthellae and turn white. This is called coral bleaching. If the water temperature does not cool down, bleaching can be fatal to corals. Guam lost a third of its shallow corals between 2013 and 2017 because of this and other factors.

Do you know a little knowledge about MATAPANG?
The origin of the place name Matapang is taken from the chief of Matå'pang, a famous chief of the Chamorro tribe in history. He once rebelled against the Spanish colonies and rejected the Christian faith in order to preserve the cultural heritage of Chamorro.

Do you know a little knowledge about the Piti bomb hole?
The bomb hole in the Piti Bomb Hole Marine Reserve in Guam is a natural hot spring. Fresh water will infiltrate from the ground and cover 25-30 feet. I once found two molluscs and one kind of sea urchin, which are unique in the world. Among all marine reserves in Guam, the ecology of the Piti bomb hole is the most diverse.
