Because its running a lot of 'fish-about' program such as river monster, giant fins, and if do not miss call this week is a shark week. who doesn't know that fiercing teeth of great white shark...scary. and you now natgeo producing a nice DVD series, that you can burn it using dvd kosong.
Okay now come the main part....this several fishes that i think is immense in size and they're amazing and at the same time adorable :
blue fin tuna
some cat fish look like in himalaya
Aaah there are too many.....you should see the program yourself i bet you wont regret...my best regards for those who love animal. and keep the nature healthy.

Antiteori - ini zaman anti teori
Even made in indonesian language. This blog has a very informative content including blogging tutorial, free SMS, reflection section, and most imprtant is internet business.
The author, danielrannu aka. buyungupik has his own remarkable reputation and credibility on indonesian blogosphere. His way of writing is as unique as his blog template...easy reading, comperhensive and firm also.
He has his own point of view on responsing critical issues like internet scam, and multi-level-marketing business scheme. Overall, i will give antiteori-ini zaman anti teori a deserve score 7 of 10. thanx for danielrannu aka.buyungupik to give me a chance to write review on your blog. Keep blogging spirit bro =)
Prehistoric monster fish, Thalassophryne amazonica
The oddly-named Prehistoric monster fish is a venomous batrachoidid from South America. Matt Clarke explains how to keep and breed it.
Common name: Prehistoric monster fish
Scientific name: Thalassophryne amazonica
Pronounced: Tha-lass-oh-fry-nee amazon-eye-ka
Origin: Peru, Brazil and Ecuador; Rio Conambo, Corriantes and Shiona.
Water: Seems to be quite adaptable. Can be kept in both soft, acidic water and slightly hard, alkaline water. Salt is not necessary.
Diet: Fish or shrimps, preferably frozen. Some fishkeepers claim that the species is reluctant to accept anything other than live fishes. Live river shrimp is well worth a try.
Temperament: Very shy and retiring. Will spend most of the day submerged beneath the sand. Fiercely predatory and will consume any smaller fishes that pass overhead.
Stocking: Can be kept in groups.
Aquarium: The aquarium must have a deep sandy substrate to allow the fish to burrow. A 5-8cm/2-3" layer of silver sand is ideal. The species is inactive so a large tank is not necessary. An adult pair can be easily kept in a 61cm/24" aquarium.
Sexing: No external sexual differences are known but the sexually mature females are much larger than males. Difficult to spot other differences due to the burrowing behaviour of this species.
Breeding: A small number of large (7mm) amber eggs are laid over a three to four-day period. The eggs are non-adhesive and have a large semi-adhesive filament on the underside. Most eggs are buried within the sand, a small number are scattered upon the substrate. For more details on breeding this species check out my other article on monster fish.
Notes: This weird nocturnal oddball isn't often seen above the sand - you may just see its eyes sticking out
of the substrate. The spines may be venomous - handle with care. It's a member of the family Batrachoididae, commonly known as toadfishes or batrachoidids (pronounced bat-ra-koy-dids, not bat-ra-koids).
Identification: This species was originally traded as Daector sp. and was misidentified in an Aqualog guidebook. Back in 2002, before the species was known by fishkeepers, I contacted batrachoidid taxonomist Dr Bruce Collette who first confirmed the true identity of the fish as T. amazonica. PFK was the first to publish the true identity of this species. It is also being sold under the name Potamobatrachun tripinosus by suppliers in Peru.
Related species: There are at least five other species in the Thalassophryne genus, including: Thalassophryne nattereri (found in the western Atlantic); Thalassophryne maculosa (found in the western central Atlantic); Thalassophryne megalops (from the Gulf of Panama); Thalassophryne montevidensis (from the south Atlantic around Montevideo) and Thalassophryne punctata (from the south west Atlantic). As far as I am aware, T. amazonica, is the only true freshwater species.
Alternatives: The Toadfish, Allenbatrachus grunniens, is similar in appearance. This species benefits from some salt in the water.
Price: Prices can range from under a tenner to �30 or �40 depending on the supplier.

Ocean sunfish are native to the temperate and tropical waters of every ocean in the world. Molagenotypes appear to vary widely between the AtlanticPacific, but genetic differences between individuals in the Northern and Southern Hemispheres are minimal. and
Sunfish are pelagic and swim at depths of up to 591 metres (1,939 ft). Contrary to the general perception that sunfish spend much of their time basking at the surface, research suggests that adult M. mola actually spend a large portion of their lives submerged at depths greater than 200 metres (656.2 ft), occupying both the epipelagic and mesopelagic zones. They stay in water warmer than 10 °C (50 °F) most of times. In fact, prolonged periods spent in water at temperatures of 12° C (53 °F) or lower can lead to disorientation and eventual death. Others point to sightings of the fish in colder waters such as those southwest of England outside of its usual habitat as evidence of increasing marine temperatures. Researches theorize that the basking behavior at the surface may be a method of "thermally recharging" following dives into deeper, colder water.
Sunfish are usually found alone, but occasionally in pairs. They swim primarily in open waters, but are sometimes seen near kelp beds taking advantage of resident populations of smaller fish which remove ectoparasites from their skin. Because sunfish must consume a large volume of prey, their presence in a given area may be used as an indicator of nutrient-rich waters where endangered species may be found.
Despite their size, ocean sunfish are docile, and pose no threat to human divers. Areas where they are commonly found are popular destination for sport dives, and sunfish at some locations have reportedly become familiar with divers. In fact, the fish is more threatening to boaters than swimmers, as its immense size and weight can cause significant damage when impacted by watercraft. Collisions with sunfish may cause damage to the hull of a boat, and their bodies can become lodged in the propellers of larger ships.
The flesh of the ocean sunfish is considered a delicacy in some regions, the largest markets being Taiwan and Japan. All parts of the sunfish are used in cuisine, from the fins to the internal organs. Some parts of the fish are used in some areas of traditional medicine.
Sunfish are accidentally but frequently caught in drift gillnet fisheries, making up nearly 30% of the total catch of the swordfish fishery employing drift gillnet in California. The by-catch rate is even higher for the Mediterranean swordfish industry, with a 71% to 90% of total catch being sunfish.
The fishery, bycatch and destruction of ocean sunfish is unregulated worldwide. In some areas, the fish are "finned" by fishermen who regard them as worthless bait thieves. This process, in which the fins are cut off, results in the eventual death of the fish, because it can no longer propel itself without its dorsal and anal fins. The species is also threatened by floating trash such as plastic bags which resemble jellyfish, its main diet. Bags can choke and suffocate an individual or fill its stomach to the extent that it starves.
Many areas of sunfish biology remain poorly understood, and various research efforts are underway, including aerial surveys of mola populations, satellite surveillance using pop-off satellite tags, genetic analysis of tissue samples, and collection of amateur sighting data. Recent studies indicate a decrease in sunfish populations that may be caused by more frequent bycatch and the increasing popularity of sunfish in human diet.
