A sharks diet is very interesting. The biggest sharks eat baby fish, shrimp, plankton, and many tiny animals. Some sharks eat bony fish, squid, and can also be cannibalistic. They usually feed on smaller sharks. Great White sharks eat fish, and as they grow start to eat seals and walrus.
Important tapeworm parasites of humans Cestoda is a class of phylum platyhyelminthes. The best-known species of this class are called tapeworms. This is a class of parasitic flatworms, their life histories are vary but they mostly live in the digestive tracts or gut of humans and other vertebrates as adult, and sometimes they are present in the bodies of animals as juveniles. All cestodes contain atleast one and often more than one host. They lack digestive tract, mouth and senory organs, they have unique body extension called microtiches which help in absorption of host nutrients.
Fish for Small Unheated Aquariums and Goldfish Bowls Filed under: Aquarium Fish Tanks andFish Tank Design andFreshwater Tropical Fish Certain fishes are often kept in bowls or small plastic aquariums that lack heating and filtration equipment. The fish most often kept in this way include goldfish, bettas, white cloud mountain minnows, and danios. Each of these fishes have different pros and cons when it comes to keeping them in this fashion. Goldfish, Carassius auratus: Superb in Large Unheated Aquariums Goldfish grow. Common goldfish can grow up to approximately 12 inches in length which is larger than some of the containers the juveniles are kept in.
Some octopuses also use ink to confuse a prey (especially big ones, like lobsters) before attacking it from behind. Changing color/shape: Many cephalopods are able to change their color and shape. Through controlling single pigment cells, cephalopods are capable of making different patterns and colors. For example, ready-to mate squids express their readiness through expressing certain colors. The change of color and shape are also used to camouflage animals when hiding from enemies or ambushing prey.
Rene Ismail McKenna - C 9th Grade Biology PBA American Lobster - Homarus americanus Ecosystem/Ecology of Homarus americanus Adult American lobsters tend to dwell in depths of below 50 meters. However, some can live at depths of about 750 meters. They can weigh up to 44 pounds and reach a length of about 25 inches, however they are typically around 2 feet long and weigh 3 pounds. The American lobster’s preferable habitat is on rocky surfaces covered with algae, because algae attract animals that the lobsters prey on. This habitat allows the lobster to hide within the cracks, where it can hide from predators in its environment such as flounder, cod, crabs and eels.
Sea otters are omnivores as they do eat kelp and other sea-going plants. Regardless of this however, most sea otter people have an essentially flesh eating diet with sea otters known to eat more than 40 unique types of marine creatures. The sea otter chiefly chases ocean urchins, mollusks, crabs, snails and little fish in the water. The sea otter is one of only a handful couple of creatures on the planet that has the striking characteristic of utilizing devices, for example, rocks, keeping in mind the end goal to get at it 's prey. Sea otters have couple of normal predators in the ocean because of their vast size.
Once an alligator “closes it jaw on a limb the force is so great that getting the alligator to open its mouth again is virtually impossible “ (Strawn 43 ). The adult reptile “has small legs and webbed feet that are designed for “propulsion and maneuvering but not for attack” (Visiting the Heart of Alligator Country) However the “swipe of a gators tail can knock a person into the water when it is most agile, powerful and destructful” (Strawn 43). Not to men-tion an alligators tail is what gives it it’s speed of up to approximately 20 miles per hour in water but then becomes a slower awkward giant on land. This sounds to be very similar to that of some of the dinosaurs from many years
They have well-developed and symmetrical gills over which drawn water flows. The flow of water carries the waste and reproductive products. Movement: Although abalones occur in the same place, they may use their muscular foot with its suction power to move, cling and stay tight with the substrate surfaces. Feeding habits: In nature, abalone eats marine algae with a particular preference to large brown algae such as giant kelp and other kelp species. While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food.
It holds the crab on for a while and then swallows it. Common Merganser Common mergansers are large fishing ducks. They are carnivorous, do not eat any plants. Their long and narrow saw-bills are well adopted to catch fishes. Often they appear in pairs or family groups.
Cuttlefishes Introduction: Cuttlefish are small to medium sized marine animals that belong to the class Cephalopoda, which also includes squids, and octopodes. Despite their name, cuttlefish are not fish but they are molluscs. There are more than 100 species of cuttlefish which significantly vary in size from the small ones of about 15 cm in length to the Australian giant cuttlefish which can grow to up to about 50 cm in length (excluding its tentacles) and about 10 kg in weight. Based on research findings, cuttlefish have one of the largest brain-to-body size ratios of all invertebrates indicating that cuttlefish are among the most intelligent invertebrates. Distribution and habitats: The family Sepiidae, which contains all cuttlefish, is found in shallow temperate and tropical waters.
The Texas rig is a rig that uses the method of securing a hook to a soft-PVC plastic bait-worm, lizard, crawfish, by burying the hook point into the body of the lure. The “Texas rig” is probably the most popular and most recognized method of fishing plastic worms. This rig has a bullet shaped sinker (of any size), a single hook (called a Sproat, Offset or Worm hook). This rig can be used in any depth of in any type of cover. The type of plastic bait that you attach is usually a plastic worm or lizard of some size (Chen).
The colors that the Stingray embody allow them to bury themselves in the surface of the sand and move without being detected. The skin of the Common Stingray compose of scales called “Dermal Denticles”. These V-shaped scales give off the slippery feel of Stingrays decreasing drag and turbulence when gliding through water. Similarly to Sharks, this feature of their skin allows them to be stealthy hunters swimming faster and quieter. The only difference between the two is that sharks have more aligned dermal dencticles pointing towards the back of their body while stingrays have their scales much more spread apart with irregular patterns.
Male mature to be 2 meters maximum, females mature to be 2.6 to 4 meters long(Carson, 2015). Their average weight is 551.61 pounds to 1,102.31 pounds. The mako shark 's skin is smooth which helps the shark to swim as fast as possible. Mako sharks are very diverse in where they live. For example,
They aren’t even very similar to a fish too. Seahorses don’t swim very fast either, or have scales, like all fish. Instead the seahorse has bony plates. Bony plates are little plates that are arranged in tiny knobs making it visible where they join together. Most of you would think the female seahorses are the ones that give birth to baby seahorses.
