Killer Whales are marine animals that live in oceans all over the world. Although they live in many oceans, they seem to prefer coastal waters and cooler regions. The Killer Whale, sometimes called an Orca, sometimes enters estuaries, but doesn’t go far from the sea. Killer whales are one of the top predators in the sea. They are good hunters that eat a large variety of fish, squid, sharks, marine mammals (such as whales and seals), turtles, octopi, and birds (penguins and gulls).
MY QUESTION WAS: How do crustaceans obtain oxygen and what do they eat? The largest member of the arthropod family is the subphylum (crustaceans). Shrimps, crabs, lobsters, prawns, and barnacles are all examples of crustaceans. There are almost 30,000 species of crustaceans worldwide. They live in sea or fresh water.
There are many individual species in each of the categories. Such as blue whales, salmon, and great white sharks. Many fish have adapted in special ways for self-defense. For example cuttlefish
The pots were about 3 feet 6 inches and contained two to three dozen good size crayfish weighing about two several pounds. The men said it was about one hundred and fifteen to three hundred feet long. Another eyewitness saw a great white shark the size of a tractor trailer had attacked a person. Many sharks have been clocked out as fast as 1.5 miles and the mega shark could probably swim in a longer distance since this is a bigger shark. Two percent of the ocean has been overlooked by people ant it leaves ninety-eight percent of the ocean for the megladon can swim.
It’s been recorded that a researcher found a nest that weighed two tons. The many fascinating things about eagles are plentiful; they can fly to an altitude of 10, 000 feet and reach high speeds of 30 to 35 mph. Eagles soar above the storm clouds. The eagle can dive at speeds over 100 mph. I have also realized in my reading and researching that the eagle can actually swim.
(Chesapeake Bay.net) With that being said, it isn’t a surprise that the Chesapeake Bay literally translates to “great shellfish bay”, but it would not hold this title for long. By the early 20th century nearly three-quarters of the bay’s oyster reef population have been over-harvested using dredging techniques. (Oysters in the Chesapeake) Today, overharvesting has led the remaining oyster population in the bay to be only one percent of its historical amount and now the remaining population faces problems with pollution, diseases, reproduction problems, and continued harvesting. The Chesapeake Bay is a vast system of waterways with an even vaster watershed that is 64,000 square miles with an estimated 17 million people living in this area. ( Chesapeake Bay Program)
There are also quite a few that are between 15mm and 19.99mm but not many that are longer. In comparison, the planehead filefish samples have a high frequency of individuals over a wider range of length, from 10mm to 34.99mm. The blue runner had a large number of individuals “hatched” between 6/22 and 7/2, and the planehead filefish samples were hatched over a longer period of time. Blue runner has a higher frequency of individuals between 13 and 23 days old with only a few older and none younger, while planehead filefish have a moderate frequency of individuals that range from 8 to 35 days old with only a few older and none
* 600 high lakes, two large lakes and more than 70 miles of intertidal habitats along the Pacific Coast. * Lake Ozette – the third largest natural lake in Washington State. * 31 native freshwater species from 11 different families of fish. * At least 70 unique populations of Pacific salmon, trout and char. * 5 non-native fish species: brook trout, yellow perch, largemouth bass, yellow bullhead and American shad.
The plants release dissolved oxygen and harbor fish and shellfish (Franklin, 2001). They swim in large schools close to the water’s surface. Throughout the spring, the schools of younger, smaller fish are found in estuaries, such as the Chesapeake Bay, and the larger, older fish are found further offshore and up north. Menhaden also play an important role to the fisheries, especially along the Atlantic and Gulf coasts. Humans don’t actually
At dusk, they head seaward. After sunset they feed near the surface and return to inshore areas at sunrise. The fish also likes frontal zones, areas where ocean currents collide and the productivity is high. Swordfish have very few predators. Orcas, sperm whales, some large sharks and humans eat swordfish.
