Transcript of sting ray
Water Organisms live in both environment Same water color Same surface temperature California Coastal waters 40-50% of the world's population's within 100km of a coast Coastal problems- sea level rise, tsunami, land slides, pollution, hurricanes Shallow water Activities can be done in the California coastal waters, like swimming, surfing, etc By: Alex Rekowski and Isaac Perner Energy Pyramid Venn Diagram Competition Humans are competition with Round Stingrays because humans catch and eat crabs and Round Stingrays eat them too. Starfish are competition with Round Stingrays because they eat clams like Round Stingrays. Round Stingray Mollusks/clams, snails octopus, squid, cuttlefish oysters, Crustaceans/crabs lobsters, shrimp, barnacles cope pods, krill, crayfish Bony Fish/ seahorses, tuna, red, lionfish, giant frogfish Green sea urchins Crustaceans Plankton Small food particles Scraps/ Plant reamins Plankton Food Web Dead creatures Environmental Issues Round Stingrays suffer from tourist hotspots in the Cayman Islands. They suffer from all the human attention. Humans disturb Round Stingrays rest time.
There are usually 2,500 visitors at a time. Habitat Niche Round stingrays like to be close to shore at 15m deep.
they like a soft bottomed (mud or sand) habitat.
They like an abundant amount of eel grass. They use eel grass for camouflage.
Round stingrays like to be in rocky reefs.
They live in waters that go from 10c-50c.
They stay in shallower waters in Spring, Summer and Fall and they move to deeper waters in the Winter where the temperatures are more stable. Symbiosis Round Stingray are close to Spanish Hogfish and Bluehead Wrasses. Spanish Hogfish and Bluehead follow the Round Stingray and eat whatever the round stingray doesn't eat they eat. Spanish hogfish and Bluehead are both fish. Puffer fish are carnivores.
They grow up to 3 feet.
They are slow and somewhat clumsy fish. That makes them vulnerable to predators.
Puffer fish use their highly elastic stomachs to ingest huge amounts water(air if necessary)to turn themselves into a ball several times their normal size.
Puffer fish have enough toxic in them to kill 30 adults.There is no antidote to the toxin.
The meat of the puffer fish is considered a delicacy.
There are 120 species of puffer fish.
They have rough and spiky skin.
Puffer fish eat,invertebrates algae, muscles, clams and shellfish. Puffer Fish Predator Niche A predator of the Round stingray is a Hammerhead shark. Hammerhead sharks usually prey on the weak, ill, injured and dying prey because its easier to eat. Prey Niche The round stingray stay hidden in the sand until prey comes by and the stingray its it. Whatever the stingrays don't eat the fish above them eat whatever the stingrays don't eat. Round stingrays eat worms, crabs, clams, snails and small fish. Producer Niche Macrocystis Pyrifera is a producer in the California Coastal Waters because it makes its own food and its energy source. Another name for Macrocystis Pyrifera is Giant Kelp. Niche Consumer The Round Stingray is a consumer of the California Coastal Waters because Round Stingrays eat other organisms to get energy. Scavenger Niche Crabs is a scavenger of the California Coastal waters because they are bottom feeders on the Estuarine layer. They will eat anything they find that is edible to eat. Decomposer Niche Shrimp are decomposers of the California Coastal Waters because they eat scraps of, dead creatures to get their energy. Niche Perfect suit for California Coastal Waters The Round Stingray is perfectly suited for the California Coastal Waters because they stay on the sand until a prey goes by and the Round Stingray will kill its prey. It has all their prey by their habitat so they won't starve. Round Stingrays live in saltwater. The Water Cycle Similarities and differences of biotic and abiotic factors in the California Coastal Waters Similarities and differences of biotic and abiotic factors of the coastal waters. Some differences are: biotic are alive factors and abiotic factors are not. Aboitic factors help biotic factors survive. Some examples of abiotic factors are air, water, soil, temperature and rocks. Some examples of biotic factors are animals, trees, and bacteria. Some similarities are: They both affect the environment. If one factor changes, it impacts the availability of other resources with system. They create a system of an ecosystem Geographical Map 2 examples of my biome on Earth 1: California Coastal Waters 2: Florida Coastal waters California Coastal waters The California coastal waters are from shorelines out to the federal 12 mile limit. Near shore waters provide rich and varied habitat for a diversity of marine waters, invertebrates, fish, seabirds, mammals and vast numbers of algae inhabit these shallow waters. The California Sea lion is known for their intelligence, playfulness and noisy barking. The males color is chocolate brown and the females golden brown. Their diet includes squid, octopus, fish and sometimes clams. California Sea Lion Marine algae lacks true roots, stems, leaves and flowers. The weight of the Marine algae is supported by water. Some have pneumatocysts which are gas filled bladders that float by the blades, close to waters surface to maximize their access to sunlight. Marine Algae Limiting Factor The limiting factor of the Round Stingray is the Hammerhead sharks. If the Round Stingray population gets out of check, Round Stingrays eat to many clams, oysters, scallops, shrimp, octopuses, etc... Round Stingray is hammerhead's favorite meal. Hammerhead sharks help Round Stingray's population stay balanced. Hammerhead Sharks (Limiting Factor) Fish is their type of organism. They are carnivores. They live for an average life of 20-30 years. Their size is 13-20 ft. long. Their weight is 500-1000 lbs. Hammerhead sharks use their wide heads to attack stingrays, pinning the winged fish against the sea floor. Hammerhead sharks are often seen in the mass summer migrations seeking cooler water. Their oddly shaped heads improve their ability to find prey. their diet includes smaller fish, octopuses, squid, crustaceans, stingrays. Macrocystis Pyifera Its the largest of algae. Its name is Giant Kelp too. It Receives Giant Kelp from its incredible size. Individuals may grow to up to 50 meters long. Its of the fastest-growing organisms on Earth. Its fond in the Coastal waters of North America (Alaska to California). Secondary Succession and Primary Succession Earthquakes are secondary successions because they shake up the California Coastal waters habitat and organism life so it will reduce the number of species in the California Coastal waters.
We couldn't find any primary succession of the California coastal waters Climate and precipitation Southern California Coastal waters are usually between 60-70 degrees F. California coast is warm and not that much rain. Phylum Chlorphta
Green algae Contains over 7,000 species of green algae. Sea lettuce: bright green algae extremely thin and translucent gut weed / hollow green weeds: flattened green tubes and community inhabit the high intertidal zone of coasts and estuaries. Dead man's finger: Dark green with finger like blades. It's found from middle intertidal to sub tidal zones. Green algae Abiotic Requirements They need sunlight to grow better. When temperature rises, nutrients for it to produce algal blooms, they also need water to grow. Resources we used for every project animal-world.com
