Lionfish – Pterois volitans
The lionfish, scientifically known as Pterois volitans, is a species of poisonous spiny fish belonging to the family Scorpaenidae. This fish lives in coral reefs. In the wild they are found in the Indo-Pacific region.
Inhabit lagoon and seaward reefs from turbid inshore areas to depths of 50 m. Often solitary, lionfishes hide in unexposed places at daytime often with head down and practically immobile. Pelagic juveniles expatriate over great distances and the reason for their broad geographical range. The juvenile, usually living in deep waters. Hunt small fishes, shrimps, and crabs at night, using its widespread pectorals trapping prey into a corner, stunning it and then swallowing it in one sweep. Dorsal spines are venomous; the sting can be treated by heating the afflicted part and application of corticoids.
Sea turtle- Chelonioidea
For over 100 million years, sea turtles are distributed in large quantities across the oceans, playing an important role for the marine and coastal ecosystems. However, over the last 200 years, human activities threaten the survival of the ocean.
Sea turtles (superfamily Chelonioidea) are reptiles of the order Testudines and of the suborder Cryptodira. The seven existing species of sea turtles in the world are the green sea turtle, loggerhead sea turtle, Kemp’s ridley sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle, and leatherback sea turtle. The IUCN Red List classifies all species of sea turtle as either “Vulnerable”, “Endangered” or “Critically Endangered”.
There are five species of sea turtles in Vietnam: leatherback (Dermochelys coriacea), green (Chelonia mydas), loggerhead (Carretta ceratta), olive ridley (Lepidochelys olivacea), and hawksbill (Eretmochelys imbricate). The IUCN Red List of Threatened Species lists the first four as Endangered, and the hawksbill turtle as Critically Endangered.
Sea turtles usually lay around 100 eggs at a time, but on average only one of the eggs from the nest will survive to adulthood. Adult sea turtles have few predators. Large aquatic carnivores such as sharks and crocodiles are their biggest threats; however, reports of terrestrial predators attacking nesting females are not uncommon. While many of the things that endanger sea turtles are natural predators, increasingly many threats to the sea turtle species have arrived with the ever-growing presence of humans.
The Zebra Morays have a dark red-brown coloration with more than 100 narrow vertical while bands run from the tip of their nose to the tip of their tail. They have no pectoral fins, pelvic fins or scales. The Zebra Morays are a benthic species found in shallow coastal reef environments at depths from 1-39 m. They have poor eyesight and a keen sense of smell. They are very secretive being active nighttime predators that consume crustaceans, mollusks, and sea urchins.
Size: 150 cm
Distribution: Indo – Pacific
Sam- Tachypleus tridentatus (Leach, 1819)
Distribution: Southeast and East Asia
Size: 79.5 cm
Characteristics: Tri-spine horseshoe crabs are probablt the most ancient living arthropods know nowadays and are considered “living fossils”. Despite their name, these animals are not crabs at all, but are related to scorpions, spiders. It has a dorsal surface folded ventrally, which forms a triangular shape on the surface, which narrows towards the mouth. The females grow larger than males. They have nocturnal habits and usually remain buried in the ground throughout the day. They usually live in pair on sandy and silty substrates in coastal marine and brackish water. Food on mollusks, worms, bivalves, and other benthic invertebrates. They can find in The IUCN red list of threatened species.
Distribution: almost seas in over the world.
Characteristics: Soft corals are soft bodies made up of a large number of polyps connected by fleshy tissue. They lack the limestone skeleton found on their relatives, the hard coral. The term “soft” is a bit misleading because these corals have numerous tiny, needle-like spicules in their tissues. A part from their swaying bodies and jelly like feel, soft corals are distinguished by the eight tentacles on cach polyp and have a feathery appearance. Almost soft corals utilize zooxanthella as a major energy source. However, most will readily eat any free floating food, such as zooplankton, out of the water column.
Banggan Cardinal- pterapogon kauderni (Koumans, 1933)
Distribution: Banggai Islands-Indonesia
Maximum size: 8cm
The Baggai cardinalfish are sexually monomorphic. The male can be differentiated from the female by a conspicuous, enlarged oral capacity, which is apeparent only when they are brooding. When the male accepted the female courting, the female expels eggs and the female takes the egg. The female broods the egg on his mouth up to 30 days, once the incubation period is complete, babies come out of the male’s mouth. During that time the male fish will not eat. It is listed as an endangered species by the IUCN.
Feeds on plankton and small, bottom-dwelling crustaceans.
Distribition: Indo – Pacific
Characteristics: Identified by their long horns that protrudes from the front of its head, rather like those of a cow located on their heads and below their tails. They have a hard external skin made of fused scales, forming a box-like enclosure called carapace, with holes for movable part that are sealed with tough skin. Longhorn cowfish have poisonous flesh and they also release ostracitoxin when becomes stressed by sudden movements, bright lights and loud sounds. Its food is benthic algae, microorganisms, mollusks, small crustaceans and small fishes.
Seahorse – Hippocampus kellogi Jordan & Snyder 1902.
Distribution: Australia , Indo-Pacific
Size: Up to 25 cm (H.kelleogi)
Characteristic: female deposits her eggs in the pouch of her partner. The male broods the eggs and gives birth. Seahorse is quite faithful. Artificial breeding has been succeed in Institiute of Oceanography. They need to be protected in nature because of the overfishing
This whale skeleton was found on December 8th, 1994 by farmers of Hai Cuong Village, Hai Hau District, Nam Ha Province (North Vetnam) while digging an irrigational canal.
It was buried about 1,2m underground and 4km far from the Sea. It is 18m in length and 10 tons in weight.
Sea Cow – Dugong Dugon (Muller, 1776)
Dugong Dugonis the protagonist of the Legend of the “Little Mermaid”. The legend told that, when Western sailors see the fish under the water and breastfeed, as well as the voices of the lullabies, they thought that they were old people who were born the legend of “The Little Mermaid” .
The sea cow skeleton has found on 22-1-1997 in Lo Voi of Con Dao National Park and was donated to the Museum of Nha Trang Marine Science in January 11-1997. The Skeleton got 2. 7 m long.
The sea cow was stuck in fishermen’s net on 23 Dec 2003 in Ganh Dau Village, Phu Quoc District, Kien Giang province. It is 275 cm long and 400 kg in weight. (Transfered by Kien Giang Agency of resource Protection Department)
Manta birostris is one of the largest stingrays in the world. This specimen, The weight before processed is up to 1 ton, only the liver is up to 51 kg.
The Oceanographic museum is currently storing and preserving a large collection of marine creatures and a quarter with about 20,000 samples of 7,000 species (including the groups: marine flora, sponge, coelenterata, mollusc, crustacean, echinoderm, fish, reptile, marine mammal). A set of marine life samples includes species existing in Vietnamese sea and adjacent waters.
The number of samples in the museum has roughly 60,000 samples of 10,000 species, collected from 1923, but due to the ups and downs of the country through history periods, the number of specimens has been greatly reduced due to loss and damage corrupted. Beside the valuable scientific samples, the Museum also preserves many rare specimens such as sturgeon (Acipenser sinensis), Manta ray (Manta birostris), king crab (Paralithoides sp.), giant flying cuttlefish (Thysanoteuthis rhombus), the Son (Caretta Caretta), Leatherbacks (Dermochelys coriacea), The Bell fish (Pseudorca Panthera), seal (Phoca Larga), etc., the rare sea beasts are at risk of extinction such as sea cattle (Dugong dugon). The template set is confirmed by the Vietnam record organisation as the “oldest, largest, greatest marine life model in Vietnam”.
