Hydra is a genus of simple fresh-water animal possessing radial symmetry. Hydras are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa. They can be found in most unpolluted fresh-water ponds, lakes and streams in the temperate and tropical regions and can be found by gently sweeping a collecting net through weedy areas. They are usually a few millimetres long and are best studied with a microscope. Biologists are especially interested in hydras due to their regenerative ability; and that they appear not to age or die of old age. However, there is not scientific unanimity yet on whether Hydra undergo senescence, as discussed below.

The plakat is just the short finned version of the Betta Splendens. There are wild-type plakats (which look like the bettas caught in their natural habitats), Traditional Show plakats (symmetrical wild-type finnage with some enhancement), Modern Show plakats (multi-branching caudals, extended dorsals, longer anals/ventrals, cultivated colors) and Fighter plakats (bettas that have been selectively bred for fighting ability, such as aggression, sharper teeth, harder scales and longevity).
Plakats are generally more active than the long finned version, not being hampered down with excessive finnage. This, along with their resistance to disease, makes them a favorite among betta enthusiasts and collectors.

In Greek mythology, Nemesis (Greek, Νέμεσις), also called Rhamnousia/Rhamnusia ("the goddess of Rhamnous") at her sanctuary at Rhamnous, north of Marathon, was the spirit of divine retribution against those who succumb to hubris (arrogance before the gods). The Greeks personified vengeful fate as a remorseless goddess. The name Nemesis is related to the Greek word νέμειν [némein], meaning "to give what is due". The Romans equated the Greek Nemesis with Invidia.
"Nemesis" is now often used as a term to describe one's worst enemy, normally someone or something that is the exact opposite of oneself but is also somehow similar. For example, Professor Moriarty is frequently described as the nemesis of Sherlock Holmes.
The word Nemesis originally meant the distributor of fortune, neither good nor bad, simply in due proportion to each according to what was deserved; then, nemesis came to suggest the resentment caused by any disturbance of this right proportion, the sense of justice which could not allow it to pass unpunished. O. Gruppe (1906) and others connect the name with "to feel just resentment". From the 4th century onwards, Nemesis, as the just balancer of Fortune's chance, could be associated with Tyche.
In the Greek tragedies Nemesis appears chiefly as the avenger of crime and the punisher of hubris, and as such is akin to Atë and the Erinyes. She was sometimes called Adrasteia, probably meaning "one from whom there is no escape"; her epithet Erinys ("implacable") is specially applied to Demeter and the Phrygian mother goddess, Cybele.

พุตากะเก เขี้ยวแก้วทั้ง 4 ดุจตรีเพชร
หนุมาน มะอะอุปลา ใดมารอนราน วินาศสันติ"
"Oom you are the real fighter, the Superior.
You are the Mighty Mega-power Worrier, the LORD of all fish in the Oceania.
Your dynamic crystal scale is as tough as armour diamond.
The four quartz teeth as sharp as Shiva's spear
Hanumana, Oh the great fish, no one can defeat you, the Destroyer."

Anglerfish are the members of the order Lophiiformes (pronounced /ˌlɑːfiːəˈfɔrmiːz/). They are bony fish named for their characteristic mode of predation, wherein a fleshy growth from the fish's head (the esca or illicium) acts as a lure; this is considered analogous to angling.
Some anglerfish are pelagic (live in the open water), while others are benthic (bottom-dwelling). Some live in the deep sea (e.g. Ceratiidae) and others on the continental shelf (e.g. the frogfishes Antennariidae and the monkfish/goosefishLophiidae). They occur worldwide. Pelagic forms are most laterally (sideways) compressed whereas the benthic forms are often extremely dorsoventrally compressed (depressed) often with large upward pointing mouths.
The fish are named for their characteristic method of predation. Anglerfishes typically have at least one long filament sprouting from the middle of the head; these are the detached and modified three first spines of the anterior dorsal fin. In most anglerfish species, the longest filament is the first (the illicium). This first spine protrudes above the fish's eyes, and terminates in an irregular growth of flesh (the esca) at the tip of the spine. The spine is movable in all directions, and the esca can be wiggled so as to resemble a prey animal, and thus to act as bait to lure other predators close enough for the anglerfish to devour them whole. The jaws are triggered in automatic reflex by contact with the tentacle.
