Assuming the fish could both survive in whatever water they were in..... Which i think is your plan...\n\nOne on one.  Barracuda, one bite, dead lil river fish.\n\nSmall group.10-30 of each. Barracuda, even though piranha are vicious Little critters, and can strip an animal in a few minuets, they generally are not being eaten during the fight.  Barracuda are mean, and huge, and have pretty decent Armour in the form of scales.  So, still Barracuda.\n\nLarge school of each.  This is where the piranha get their advantage.  One is not dangerous, 10 are not particularly dangerous, 300 are very dangerous.  Still, the nip a little here, nip a little there versus the one bite yer dead of the barracuda.......\n\nI'm thinking even numbers, the barracuda wins all the time.  In a weight verses weight fight, the piranha win, maybe.  Still put my money on the barracuda.  They are more some of the most agressive fish on the planet.  Have had one jump in the boat i was fishing in.  I think they may be a bit psychotic. lol

hookworms and liver flukes are parasites. Leeches might be considered parasites as well, but I'm not sure, the others I am sure of. I think the jellyfish and corals mostly eat zooplankton, that is fish ova and other tiny marine organisms. Sorry I can't help you more.\n\n16 NOV 06, 0339 hrs, GMT.

The plants do not 'eat' anything the way animals eat and digest and then defecate.\n All green plants ( with out exception) have unique mechanism of Photosynthesis by means of which they prepare what they want. We, the animals, rob them of the things they have manufactured.In this case Man is more guilty than the other animals as he gives them practically nothing in return.\nThe CARBON in your question is absorbed by them from the surrounding air during photosynthesis. The equation is as follows:-\n6CO2 + 12H2O-> LIGHT&CHLOROPLAST> = C6 H12 O6 + 6H2O + 6O2\nThus carbondioxide gas(6CO2) and water(12H2O) combine together in the presence of sunlight and chloroplst to produce glucose(C6 H12 O6) , water and oxygen gas (6O2). this gas is realeased in the atmosphere!\n The CO2 gas and water is available to mankind easily but can we produce glucose? No way.This reaction will require plenty of energy for our machinary, and the veture will be immpracticable. There in lies the greatness of the Plant Kingdom!\nThe Glucose thus manufactured is then put to innumerable application by thes plants including cell wall formation and DNA synthesis.\n Other mineral requirements are absorbed by them from the soil along with water.\n lastly  CO2 + water in the hands of man = Soda water But\n         CO2 + water in the hands of Plants = Sugar.

Leaf dragons are gorgeous fish! The leaf dragon is better known as leafy sea dragon.\nThey're relatives of the seahorses and pipefishes, and actually look like extremely well camouflaged seahorses. Their bodies have excrecences that simulate underwater algae and slowly move with the water, so that they seem like masses of plants just drifting by, similar to the sea weeds.\nIn other respects, their characteristics and biology are the same as other seahorses (Family Syngnathidae).

Interesting! You've already gotten some good answers, but I'll add my two cents.\nI think that, more than being related specifically to food-habits, this trait is related to habitat and overall habitus (which includes not only food type but also food consecution mechanisms, locomotor type and other characteristics of habitat use). And of course, to evolutionary history. All lineages have adaptations and constraints of their own.\nAs a basic consideration, most animals that live in terrestrial habitats move in a mostly 2-dimensional world. Flying and climbing animals are the exception, as well as those that may expect predators to come from above. Aquatic environments, on the other hand, are always very much 3-dimensional.\n\nIf we consider vertebrates (which I guess it's what your question was aiming at), most have eyes placed more or less laterally on the head, ensuring an extensive vision field with some (small) binocular central area. Of course, the tradeoff for lateralised eyes is that reduced superimposition of both eyes' fields, thus lesser binocular vision. In the same manner, frontal eyes reduce the total field of vision.\nA (very partial) list of terrestrial vertebrates with frontal eyes and/or enhanced stereopsis (binocular vision):\n\n-Plethodontid salamanders.\n-Chameleons, geckoes, varanids (Komodo dragons), and many arboreal snakes, among reptiles.\n- Strigiformes (owls) and Falconiformes (eagles, hawks...), but also the kakapo, a nocturnal Australian parrot, and the frogmouths (Caprimulgiformes Podargidae). \n-Many generalized marsupials such as opossums; primates and felids.\n\nNot all these animals are predators, and there are several predators with lateral eyes and mostly monocular vision. \nSo, in my opinion, the main factor is not so much what you eat, but how you get it and where you usually move.\n \nFor example, let's take the case of mammals. The earliest known fossils seem to have had nocturnal habits and partially frontal eyes, such as those seen today in opossums. From there, I can visualize different evolutionary paths tending to more laterally placed eyes in animals that have to avoid predators (such as many herbivores - e.g. hoofed mammals- , insectivores or omnivores), and more frontally placed eyes in mammals that require good 3-D vision, be it hunters (as felids) or species that move in a 3-D environment (primates), and/or have nocturnal activity. \n\nOther vertebrate groups have different evolutionary paths and adaptive histories. For instance, the eyes of all birds are extremely large in comparison with other vertebrates, with very wide vision fields; and all birds have binocular vision to some extent. Only specialized predator birds have frontal eyes, but I guess that all birds use their enlarged cerebellum to calculate distances on the basis of the 20-30º binocular field. \n\nAquatic fish-like vertebrates privilege wider vision angles, but there are fish with good binocular vision, such as the hammerhead sharks and also many deep-sea bony fish species. In the case of the first ones, it could be a predator specialization, whereas in the latter case it could be related to vision in low-light environments.\n\nArthropods have a different system altogether, and I think their adaptations and constraints merit a separate discussion (what an elegant way of avoiding it!). \n\nSo, although we like to identify patterns that allow us better understanding of the biological world, I don't think there is a direct relationship with a single factor. The list of possible factors influencing vision type includes:\n- phylogenetic history (including previous adaptations and constraints)\n- locomotor habit (running, flying, climbing)\n- feeding habit (including type of food and ways of searching for it)\n- diurnal/nocturnal activity\n\nI'm sure I'm leaving important things out... I'm not even sure if this all makes sense!\n\n-----------\nUpdate: Gianguru, you're amazing.

Oh well, with that information it's easy to identy. \n\nThe  creature is Biplaium kewense. They are commonly known as "worm killers".  See the link below for some photos\n\nAs others have guessed it is a planarian. Worm killers are an exotic pest species imported from Viet Nam in the soil of potted plants. They are carnivorous and hunt earthworms and small insects. They immobilise their prey by coating them with that slime they secrete and then stick a tube into them and suck their insides out.\n\nBTW, well spotted that it uses it's head like a sensor. That is exactly what they do. There are pits under the head that act like a nose that enables the animal to track earthworms, slugs and other prey animals.

The leatherback turtle eats jellyfish. Sharks don't generally eat jellyfish unless it is about to starve. Sperm whales may perhaps eat a jellyfish. They mainly eat squid, but will probably eat one because sperm whales love fillet. They eat giant octopus too when they get a chance. Mostly invertebrates.\n\nOh, and larger jellyfish will eat smaller jellyfish. The Lion's Mane jellyfish will eat moon jellies, for instance.

animals are generally classed as carnivores (those that eat other animals), herbivores (those that eat plants) or omnivores (those that eat both plants and animals).\n\nThese classifications are not absolute.  Cats and wolves are considered carnivores, but will sometimes also eat plant material.  Hippos are considered herbivores, but have been known to eat meat too.\n\nWithin each classification, there are also different names to refer to specialities within each type.  For example, a carnivore could be called a piscivore (eats fish) or insectivore (eats insects), and a herbivore could be called a graminivore (eats grasses) or frugivore (eats fruit).

We can think in general terms of a food chain consisting of three main groupings, or trophic levels: plants, herbivores, and carnivores. Plants are at the "bottom" of the food chain—they are able to make their own food by using the energy from the sun (they are autotrophic). Because they produce their own food, they are called Producers. All other living things that can't make their own food must consumer the producers, so they are called consumers (and are heterotrophic). Consumers are higher up the food chain (at a higher trophic level) and are either herbivores (they directly consume the producers) or carnivores (they eat other consumers). Macroinvertebrates are heterotrophic and may be both herbivores and carnivores. \n\nBecause benthic macroinvertebrates eat and are eaten, they are smack-dab in the middle of the food chain, a position that is critical in a healthy stream ecosystem. Herbivorous stream bugs consume plants and algae (these bugs are the scrapers and shredders). \n\nThe benthic macroinvertebrates that eat small fish, small amphibians, and other stream bugs are the carnivores. These predaceous macroinvertebrates are the predators\n\nTo confuse matters slightly, there is another group in addition to the herbivores and carnnivores. Detritivores are sort of a combination of herbivores and carnivores. Detritivores shred and eat leaves and other organic matter that contain nourishing fungi, algae, and bacteria. They absorb the nutrients as they break down the material into smaller sizes that other bugs utilize. Detritivores are the shredders and collectors. \n\nStream bugs may get eaten by other macroinvertebrates and fish that depend upon them for food. For example, both juvenile and adult salmon eat macroinvertebrates. And not only do other consumers need them for food, but when the bugs die, they decay and leave nutrients behind that flow back into the food chain. \n\nSo without the stream bugs, organic materials won't be processed, nutrients won't get recycled back into the system, and many consumers won't have any food—in short, the system degrades until it is unhealthy or dead, then most bugs couldn't live there even if they wanted to.

Ok, you probably mean the zooplankton.\nGenerally, you would name producers the algae (phytoplankton), that   photosynthesise, primary consumers the zooplankton (or some small fish, or some insects, crustaceans, etc) that eat the producers (they are herbivorous) and secondary producers the fish or crustaceans etc that eat the primary consumers.\nIn a pond ecosystem, the main primary consumers would be some insects and zooplankton, and secondary consumers some bigger animals (not necessarily aquatic)\nI would give you some on-line references but I do not know what exactly you need to find, or how specific or general information you need. Anyways, I give you a couple of websites, but I really don't know what exactly you need.\nIf you posted a comment with more details, I could edit my answer, trying to include more info

Yes.  The simplest, and according to biologists and archaeologists was algae.  Without this plant life, there would not be life on Earth as we know it.  Over time, we gained simple grasses, ferns, moss and other simple plants.  From this, depending on the climate, animal life, amount of water, and other factors some simple plants grew to more advanced forms while at the same time others remained the same.  This is why we still have algae and ferns.\n\nIt is the same under water.  Algae is primarily a water based plant, and due to certain conditions evolved to fit their environment making the sea grasses, sea ferns, and a huge host of other sea plants both simple and complex.\n\nWhile there is some debate, however, coral is considered an animal (although it may live in semi-symbiosis with algae), and plankton may be plants, animals, or other (bacteria).

Anoles eat mosquitoes, spiders, and roaches.  They are quite common in the southern US, where many people call them 'chameleons" by mistake, because they can change from green to brown, vice/versa.  they can get up to about 8" but are more commonly seen 1/2 that size.  \nThe grownups are wary, but they will become semi-tame, when they learn you won't kill them.  The males have a red throat flap when they're horny :}

i think animalia contains all animals - fish, reptiles, mammals, birds and amphibians. dolphins are obviously not bacteria, fungi, insects, etc. if you meant mammalia it is because dolphins -\nbreathe air with lungs, not gills\nbreastfeed their young that do not hatch from eggs\nhave four chambered hearts

There are many types of worms i think it depends on the type...if you say a ringworm well microscopically its pesty carnivore coz it eats you up...but if you say an earthworm well its an omnivore coz it lives down on muddy earth deep in the soil...ok human friend but for more info browse the web human friend!!!oh! more info some poeple eat worms! YUCK!

All raccoons are nocturnal and omnivorous, eating berries, insects, eggs and small animals. Raccoons sometimes wash, or douse, their food in water before eating it.

...and some insects visit only specific animals. It's known as coevolution - they grew up together over millions of years to the point where some plants can't survive without certain species of insects, and vice versa; and some insects can live only on certain animals (for example, lice).\n\nCoevolution may involve pollination or, as a previously answered, the battle for plants to deter insect feeding by manufacturing secondary metabolites. In this case, insects evolve biochemical pathways to detoxify the feeding deterrents. These interactions eventually become exquisitely complex and, in many cases, exclusive to the species involved. There's alot on the web. Search for coevolution, mutualism, parsitism, symbiosis.
