Transcript of Marine Food Web

Phytoplankton is a producer, it produces its own food. Phytoplankton are prey to zooplankton, sprats, pipi, pilchards, jellyfish, tiny shrimp, whales and sea snails. Phytoplankton have the adaption to float, they have extremely light weight tissue allowing them to stay a float. They are also transparent which allows them to camouflage. Phytoplankton Marine Food Web Seaweed is a producer, produces it's own food. Seaweed is prey to crab, kina, snails, sea urchins, most types of fish and sea turtles. Seaweed has the adaption to float, they produce air bladders (called pneumatophores) which allow them to keep floating. Also to reproduce they release gametes (a cell that gets with another cell during fertilization ) into the water synchronously in response to light, temperature, or tides to increase their production rate. Seaweed Sprattus, most commonly known as sprats, are consumers, although they are herbivores, sprats eat other living organisms (consumer). They feed on phytoplankton. Sprats are the prey of Kahawai and Snapper which are mostly found in deeper water. Sprats have silver grey scales and white-grey flesh. Sprats Kina is a consumer, it eats other living organisms. Kina feed on kelp - Ecklonia Radiata, and other algae. Kina is prey to crayfish and snapper.The kina have long sharp spines which swivel and turn on a ball type socket joint. They move along using their spines. Kina crawl over seaweed and grind it up with their teeth. Kina The Hermit crab is a consumer, it eats other organisms (omnivore). Wild Hermits are scavengers meaning they'll eat things like dead fish, algae, sometimes fish waste, seaweed and meats. These crabs are decomposers resulting in them in eating other dead species, for example dead fish (as said above.) Hermit Crab Pilchards Tuatua are consumers (herbivore), they eat other living organisms such as phytoplankton. Pipi are the prey of sprats, and snapper. Pipis have a strong muscular foot inside their shells, they extend their foot outside of their shell to dig into the sand and bury themselves. Pipi bury themselves in the sand (on the shore) so that they don't get dragged out to sea by the strong currents. Pipi & Tuatua By Amber Freebury 9RH Phytoplankton is not visible to the un-aided eye (microscopic.) Seaweed can be used as food, medicine and fertilizer. Kahawai are consumers (carnivore), they eat other living organisms, they feed on sprats and other small fish. Kahawai is the prey of kingfish, and john dory. Kahawai tend to live in most coastal waters, harbours, and estuaries around New Zealand, in both the North Island and South Island. Kahawai are considered to be one of the best fighting fish in the ocean. Kahawai Snapper are consumers (carnivore), they eat other living organisms, such as sprats, kina, pipi and crab. Snapper is the prey of john dory, sharks, and barracuda. There are two main types of snapper; the red snapper and the yellow tailed snapper.
Red snapper prefer reef and rocky bottom habitats. However, in contrast, the Yellowtail snapper lives in deeper, sand-covered locations. Snapper The Kingfish is a consumer (carnivore), eats other living organisms, such as, kahawai, small snapper, sardines, squid and, sprats. The kingfish is prey to dolphins, sharks, barracuda, and seals. The kingfish is a streamlined fish, slightly flattened on it's side with a tapered head. Its color ranges from a bluish green on its back to their silvery sides. Kingfish The John Dory (also known as St. Peter's fish) is a consumer (carnivore), eats other living organisms, such as pilchards, snapper, and kahawai. John Dory are a slow swimming fish that rely on a camouflage to catch its prey. They can also catch their prey by stalking it, then shooting a tube out of its mouth to capture its prey. John Dory is the prey of black marlin, sharks, and other large bony fish. John Dory The black marlin is a consumer (carnivore), eats other living organisms as a diet. Black marlin feed on john dory, kahawai, squid, tuna, and other sea fish. Black marlin is the prey of great white sharks, and short fin mako (shark). The black marlin can look different colours underwater, for example with lots of light it looks more silvery, but in contrast, with little light the black marlin looks black. The marlin can use this to their advantage, by camouflaging in deeper darker waters when hunting. Black Marlin Seals are consumers, they eat other living organisms (carnvore), such as kingfish, penguins, squid, fish and shell fish. Seals are prey to sharks, killer whales, and polar bears. Seals have the ability to bring their highly sensitive whiskers forward to feel for fish in dark waters. They also have fur so they can keep warm in cooler waters. Seals have very flexible necks so they are able to look completely behind them, male seals use this often so they can watch over their territory. Seal The great white shark is a consumer (carnivore),eats other living organisms. This shark is one of the top predators in the ocean, it eats almost anything from plankton to black marlin and seal. There aren't many identified predators of the shark, but there are some animals that attempt to attack the shark. These sea creatures are other sharks, snails, and whales.

= Interesting facts


= Tip Pilchards are consumers (omnivores), they eat other living organisms such as water fleas, tiny prawns, phytoplankton and krill. Pilchards are prey to
sharks, whales, dolphins, sea birds, larger fish like tuna, sea lions, and seals. Pilchards are darker on the top of their back so that they are harder to be seen from above, however they are lighter on the bottom of their stomach so that they are harder to be seen from below against the light above. Sprats travel in large groups to decrease being eaten. Kina are omnivores but prefer to eat large brown seaweeds. Hermit crabs use the discarded shells of other creatures to
protect their soft bodies. In one pilchard fishing trip around 10 000 tonnes of fish are caught Tuatua live to be about 4-5, reaching their maximum size of 80mm.
Snappers are found in tropical waters sometimes in rocky areas or near coral reefs. Kahawai are known as the 'Australian Salmon' even though they are not related to salmon. St. Peter that was left there after he took a coin from within the body The black spot located at the middle of its body is said to be the thumb mark of Kingfish belong to one of the biggest families under the sea Seals are considered "the best friends of the sea."
