The Marine Biome Written by Molly Joyce A horse--like seahorse is eating shrimp with its long snout when the scuttling sound of a 10--legged red crab arises from the sandy ocean floor, its hard shell upsetting the sandy ocean floor. The crab grabs at the seahorse with its claws snapping ferociously. Crabs are one of the few animals that eat seahorses, along with some species of fish and rays. The seahorse, terrified, uses the current to float to a nearby patch of eelgrass. Once there, it vanishes, perfectly camouflaged with the eelgrass.
Baby gray whales can consume as much as 300 gallons of milk per day during their first year of birth. 44. Once a hunted and endangered species the gray whale is now considered one of the most popular marine mammals to those who participating in the whale watching industry. 45. A fully grown gray whale can weigh just as much or more than 5 adult elephants.
BEARS Did you realize that a bear can almost weigh as much as a car and can be strong enough to break parts off of a variety of items? Although they’re shy and easily frightened, you should maintain a distance. How big is a bear? For instance, a bear weighs around 500 to 900 lbs. Also bears can become around five feet long when a bear is full grown.
This graph shows a more stable recording in the movement of this type of orca; the furthest that the whale in graph B dives is about 75 meters. Resident killer whales are also known to only prefer fish, opposed to the transient killer whale, which targets marine mammals. The graph also supports the fact that resident killer whales are exactly what their name says, they are familiar with the territory they inhabit, which allows them to frequent and move about more, where as with the transient orca, they could only go so far because they navigate and dive according to where their food is. Both graphs are very distinct in terms of figuring out which type of killer whale it depicts; the resident killer whale has a very consistent dive and depth pattern, and is very easy to detect because of the obvious background of its kind—what it preys on as well as where it usually migrates to, where as the transient killer whale has a more spaced out graph, due to the fact that unlike the resident killer whale, it stays more to the coastal areas and would only dive deep to seek out other marine mammals to prey
Four million birds are estimated to use the Sea each day in the winter, more than any other resource in the nation” (DesertUSA, The Salton Sea, CA). Some rare birds that can be seen on special occasion are Bald Eagles, White Ibises, Pine Warblers, Red Crossbills, and over fifty other rarities. Some common birds are: killdeer, Caspian terns, American Avocets, Great Egrets, burrowing owls, Black-necked stilts, and Black skimmers (5). One species, the Yuma Clapper rail, relies heavily on the survival of the Salton Sea because around 40% of all Yuma Clapper rails in the United States live in the basin. These birds were listed as endangered on March 11, 1967 and also rely on the basin for crayfish to eat.
It is said that the foxes were able to cross onto the southern islands since in the past the channel between the islands narrowed down to only five miles across. The oldest fossil is about 6,000 years old. Like most foxes, Island foxes are usually solitary animals, omnivorous, and mark their territory. Island foxes are the smallest fox species in North America. Adults grow up to 12-13 inches in height.
Incredible Facts About Prehistoric Sea Turtles and Mexico Sea turtles were alive at the beginning of the Mesozoic Era 225 million years ago and survived the rise and extinction of the dinosaurs. Six of the seven surviving species are threatened by humanity. Threats to the reptiles include high attrition rates for hatchlings, loss of nesting sites, poaching, coastal development, pollution and accidental entanglement in fishing nets. These magnificent but fragile reptiles need air to breathe and places to nest on land, but they 're well-adapted to survive in oceans. The leatherback sea turtle often grows to more than 1,000 pounds, and some turtles live as long as 100 years or more.
Particularly, I believe that fossils of our ancestors show that we had to develop bipedalism because of natural selection and environmental factors. Grade I: The Lemuroids The best place to observe Lemuroids of all shapes and sizes is Madagascar, where there are more than 30 different kinds (LemurWorld). They can also be found on the Comoro Islands. They can weigh anywhere from 1 ounce to 20 pounds. There once existed
Bluebirds can sight their tiny prey items from 60 feet or more away, their diet consists of insects, caterpillars, beetles, crickets, grasshoppers, and spiders. In fall and winter, bluebirds eat large amounts of fruit including mistletoe, sumac, blueberries, black cherry, tupelo, currants, wild holly, dogwood berries, hackberries, honeysuckle, bay, pokeweed, and juniper berries. Eastern Bluebirds have been recorded eating salamanders, shrews, snakes, lizards, and tree frogs which is rare for this species. Birds of prey, snakes, and various mammals, especially cats and raccoons are the main predators of Eastern Bluebirds (MN DNR
Just What Is A Manatee? Manatees are gracious aquatic mammals, called Trichechus manatus by scientists. They grow to about 9 feet tall and a whopping 1,000 pounds. At top speed, an adult can zoom through the water at nearly 20 miles per hour, but usually choose to cruise at around 5. Often referred to as "sea cows", these gentle creatures are
The leopard seal is second only to the killer whale among Antarctica 's top predators. Its canine teeth are 2.5 cm (1 in).  It feeds on a wide variety of creatures. Smaller seals probably eat mostly krill, but also squid and fish. Larger leopard seals probably switch from krill to more substantial prey, including king, adelie, rockhopper, gentoo, emperor, and chinstrap penguins, and less frequently, other seals, such as crabeater seal.
They can produce a wide range of sounds and will "bark" when threatened; other vocalisations include a whinny (a gentle high-pitched neigh) similar to a horse and prolonged screams. [Britannica, 2009] Spider monkeys form loose groups of 15 to 25 individuals,but can have even 30 to 40. During the day, groups break up into subgroups of two to eight animals. This social structure is found in only two other types of primates: chimpanzees and Homo sapiens. The size of subgroups and the degree to which they avoid each other during the day depends on food competition and the risk of predation.
Orcas have the 2nd largest brain of all marine mammals, just three pounds less than the Sperm Whale’s 18-pound brain. For starters, orcas in each pod have their own “language,” composed of clicks, squeaks, and whistles. In addition to each orca pod having its own “language,” the orcas can decipher other pods’ languages. Orcas also have incredibly precise echolocation, a form of sonar or radar in animals. Killer whales use echolocation for a couple of things.
The komodo dragon(Varanus komodoensis) also known as the komodo monitor is a large species of lizard found in the indonesian islands of komodo,rinca,flores,gili motang and padar. A member of the monitor lizard family Varanidae, it is the biggest living species of lizard, growing to a maximum length of three meters (10 feet) in rare cases and weighing up to 70 kilograms (150 pounds). The unusually large size has been attributed to island gigantism, since no other carnivorous animals fit the niche on the islands where they live. however, recent research suggests that the huge size of komodo dragons may be better understood as representative of a relict population of very large varanid lizards that once lived across indonesia and australia most of which with other megafauna died out after pleistocene. As a result of their size komodo dragons dominate the ecosystems in which they live.
