any of the cartilaginous fishes of the order Batoidei, related to sharks and placed with them in the class Chondrichthyes. The order includes 534 species. Rays are distinguished from sharks by a flattened, disklike body, with the five gill openings and the mouth generally located on the underside. Rays are further distinguished from sharks by their greatly enlarged, winglike pectoral fins, which extend forward along the sides of the head above the gill openings. Many rays swim and breathe differently from sharks, propelling themselves with their pectoral fins and taking in water for respiration through large openings (spiracles) on the upper surface of the head, rather than through the mouth. The ray’s tail is generally long and slender and in many species bears one or more sharp, saw-edged, venomous spines that can be used to inflict painful wounds.
Rays are predominantly marine and are found in all oceans. Many are slow-moving bottom dwellers. Manta rays feed on plankton and small animals; others take various fishes and invertebrates, sometimes damaging commercially valuable shellfish beds. Other than skates, most or possibly all rays bear living young. Fertilization is internal, the male introducing sperm into the female by means of special copulatory organs (claspers) that are the modified edges of the pelvic fins.
Rays can be classified into the following groups: electric rays, sawfishes, skates, and various families of rays that have slender, whiplike tails equipped with spines and that are all-inclusively called stingrays, or whip-tailed rays.
Electric eels have an elongated, cylindrical body, typically growing to about 2 m (6 feet) in length, and 20 kg (45 pounds) in weight, making them the largest species of the Gymnotiformes.[1] The coloration is dark gray-brown on the back and yellow or orange on the belly. Mature males have a darker color on the belly. They have no scales. The mouth is square, and positioned right at the end of the snout. The anal fin extends the length of the body to the tip of the tail. As in other ostariophysan fishes, the swim bladder has two chambers. The anterior chamber is connected to the inner ear by a series of small bones derived from neck vertebrae called the Weberian apparatus which greatly enhances their hearing capability. The posterior chamber extends along the whole length of the body and is used in buoyancy. Electrophorus has a well-developed sense of hearing. Electric eels have a vascularized respiratory organ in their oral cavity (Albert, 2001). These fish are obligate air-breathers; rising to the surface every 10 minutes or so, the animal will gulp air before returning to the bottom. Nearly 80% of the oxygen used by the fish is taken in this way.[2]
Sharks (superorder Selachimorpha) are a type of fish with a full cartilaginous skeleton and a highly streamlined body. The earliest known sharks date from more than 420 million years ago.[1]
Since that time, sharks have diversified into 440 species, ranging in size from the small dwarf lanternshark, Etmopterus perryi, a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark, Rhincodon typus, the largest fish, which reaches approximately 12 metres (39 ft 4 in) and which feeds only on plankton, squid, and small fish by filter feeding. Sharks are found in all seas and are common down to depths of 2,000 metres (6,600 ft). They generally do not live in freshwater, with a few exceptions such as the bull shark and the river shark which can live both in seawater and freshwater.[2] They breathe through five to seven gill slits. Sharks have a covering of dermal denticles that protects their skin from damage and parasites, and improves their fluid dynamics so the shark can move faster. They have several sets of replaceable teeth.[3]
Well-known species such as the great white shark, tiger shark, blue shark, mako shark, and the hammerhead are apex predators, at the top of the underwater food chain. Their extraordinary skills as predators fascinate and frighten humans, even as their survival is under serious threat from fishing and other human activities.

DUGONGS (Dugong dugon Muller, 1776) IN EAST MALAYSIAN WATERSHistorically, dugongs were common in shallow coastal waters of East Malaysia and were hunted, particularly in Sabah. Today, their occurrences are rather occasional. Due to the unknown population status, the main purpose of this research is to create and compiles information on dugong distribution and abundance, and highlight threats affecting the animals in the area.
Between 1996 and 2001, we conducted boat, aerial and interview surveys, and site investigations on stranded or trapped dugongs along the coast of Sabah and Sarawak. No dugong was sighted during boat surveys. During aerial surveys, 7 sightings were made at 3 different areas. Three sightings were in Brunei Bay, one in Labuan, and three off Kudat, with a total of 18 dugongs. All dugongs sighted were very close to shore. Five sightings were of a single dugong and two sightings in Brunei Bay were of 6 and 7 dugongs, respectively. In addition, there was also in 4 occasions where a single dugong was observed from shore within the Kota Kinabalu harbour limit.
A short walk around Labuan's only Bird Park. Situated on the northern part of the island, approximately 18 kilometers from the town centre. Connected well by road and public transport is available either by taxi or by mini bus. 
Three Ostrich that were found int the Bird's Park seems to be friendly with visitors. These Ostriches sometimes to be a little bit dangerous and might bite us..... so carefull.
The Bird Park is well planned with rest and recreation centre. Come and visit and a nominal fee is RM3.00 per entry. Worth paying.
