kinsay makapost anang freshwater eel/ casili? wala man photos sa net uy....
sa toku? hehe mas mahadlok ka sa paak kai d na sila mubuhi unless itoslob nimu sa balde hehe, usually ang notion na "mupilit sa panit" kai hoax since nka ingun cla ana kai mag dagan2 man sa whole nimu na body hehehe so tablag nipilit!
regarding sa cobra, banakon japun twag anah hehe pero k2 gisend ni vahnhelsing kai layu ra jud sa naja philippinensis (mu post ku ani later, thanks sa share..) lahi rajud.
There are 4 species of Najas here in the Phils., which of two that's not endemic. The N.philippinensis, N.samarensis, N.sumatrana & O.hannah....
If you wanna know more about cobras and other elapids, PM me...
Monitor #1 : Gray’s Monitor Lizard
Com.name: Butaan
Sci.name: Varanus olivaceus (formerly V.grayi)
Classification: Reptiles
Family: monitors
Location/Origin:
Lowland dipterocarp forest in the east of Luzon and a few smaller adjacent islands in the Philippines such as Polillo Island
(Wikipedia)
It is found only on southern Luzon and Catanduanes Island in the Philippines, where it inhabits the forested slopes of low mountains.
(Other source)
status: Vulnerable
Description:
It is largely arboreal and extremely shy. It is classed as vulnerable by the IUCN because most of its habitat has been destroyed over the last 60 years.
The extraordinary ability of monitor lizards to escape notice by ecologists and other field workers, despite their large size, is exemplified best by the case of Gray's monitor lizard. For 130 years, between 1845 and 1975, o¬nly a preserved juvenile and the skull of an adult were known. Despite several thorough investigations of the Philippine Islands in which they were believed to live no further specimens were found, and the species was generally considered to have become extinct. Finally another specimen was discovered in the collection of the American Museum of Natural History (Auffenberg 1976). It had been collected o n Luzon Island during the 1930s and triggered a series of visits to the Philippines which culminated not o nly in the rediscovery of the species but also in o ne of the most comprehensive studies of the ecology of a lizard species ever performed. Gray's monitor gets its common name from its previous scientific name of Varanus grayi. It is found only on southern Luzon and Catanduanes Island in the Philippines, where it inhabits the forested slopes of low mountains. Possibly its range was much larger in the past, but the development of agriculture has removed its habitat from most valleys. The hillsides frequented by the lizard are covered with thick rainforest and have many cliffs and rock outcrops. Although its total range is small (about 5000 square km) Gray's monitor appears to be common in many areas. However its very secretive habits and cryptic colouration enable it to evade detection. The most extraordinary feature of the ecology of this lizard is its diet. Its diet consists almost entirely of fruit, especially Pandanus Juveniles feed largely o n snails and crabs but between the ages of 12-18 months the diet changes to include a large number of fruits. No other monitor lizard is known to feed o n plant matter in the wild, but in Gray's monitor it forms a major part of the diet. Other important foods are snails, crabs, spiders, beetles, birds and their eggs. Fruits are o nly eaten when they are perfectly ripe and are collected from the forest floor. Both sugary and oily fruits are eaten, but the latter are consumed in larger numbers. Oily fruits are generally avoided by vertebrates because they contain chemicals that render proteins indigestible, so the ability to feed o n them probably reduces competition between the monitor lizard and the other fruit eating birds and mammals with which it shares its range. Gray's monitor is sympatric with the water monitor V.salvator, and it has been suggested that it is o nly able to survive competition from this non-specialized, gregarious animal by adapting to a largely frugivorous diet. Although a wide range of fruits are available in tropical forests, Gray's monitor selects o nly a few of them. They appear to know the location of the trees that bear edible fruit within their home range. However although some trees bear large amounts of fruit over several months the lizards are very picky and rarely spend long feeding below an particular tree but move about to collect a variety of fruit. Nor do they gorge themselves with food in the manner of many large monitor species. Food in the stomach accounts for o nly about 2% of their body weight, although many other species are known to consume individual prey items weighing 20% or more of their own weight. The need for a wide variety of different fruits is due to complex nutritional requirements and the need to avoid ingesting too much of any of the toxins present in the fruit. Least fruit is eaten between December and February, most sugary fruits are eaten between May and July and oily fruits most abundant from August to November and from February to March.

Monitor #2 : South-East Asian Water Monitor Lizard
Com.name: Haw, Bayawak
Sci.name: Varanus salvator macromaculatus
Classification: Reptiles
Family: Monitors
Location/Origin: Siam (Thailand). Mainland Southeast Asia, Sumatra, Borneo and smaller associated offshore islands.
Description:
The Water monitor, is a large species of monitor lizard capable of growing over 3.2 meters (10.5 ft) in length, with the average size of most adults at 1.5 meters (5 ft) long. Maximum weight of Varanus salvator can be over 25 kg(55 pounds), but most are half that size. Their body is muscular with a long, powerful, laterally compressed tail. Water monitors are one of the most common monitor lizards found throughout Asia, and range fromSri Lanka, India, Indochina, the Malay Peninsula and various islands of Indonesia, living in areas close to water.

Monitor #3 : Panay Monitor Lizard
Com.name: Bayawak , Mabitang
Sci.name: Varanus Mabitang
Classification: Reptiles
Family: Monitor
Location/Origin:
Panay Island, Philippines
status: endangered
Description:
Endemic to the island of Panay, this rare species occurs in large trees in primary lowland tropical forest. The species is highly frugivorous (fruit eaters). The species is declinig due to hunting for food.
