Most jelly fish are dangerous as they sting other creatures, when touched by one of their tentacles. Clown fish are immune to stings thus why Marlin wasn’t affected. 14. Compare Dory, Bruce and Nemo, which is the best adapted for speed and why? Bruce is best adapted for speed, as he is a shark and needs to be fast to catch and hunt down his prey.
Younger lionfish have a unique tentacle above their eye sockets, which differs in appearance between species, but studies show that this tentacle has evolved over time in each species serving to attract new prey. Juvenile lionfish eat mostly invertebrates, but shift their diet to fish as adults and eat reef fish. Adult lionfish spread their pectoral fins and use them to "herd" prey. This is a very effective predatory style because it is unfamiliar to native Florida fish. However, Lionfish can have negative effects on the overall reef habitat as they can eliminate organisms which serve important ecological roles such as herbivorous fish which keep algae in-check on the reefs.
There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
Their narrow pointed teeth are ideal for holding prey, most of which is swallowed whole. Tests on the feeding habits of angel sharks have shown that they react to any passing prey, spitting out anything that does not appeal to their appetite. They have complete faith in their camouflage when approached by divers but will inflict a shallow bite if harassed. The various species of Angel sharks range in size up to 6.5 feet (2 m) long and are mostly bottom dwellers that live on ocean floors of depths from 10 to 4,300 feet (3 to 1300 m). They sometimes prefer however, sandy near shore habitats.
The Northern Snakehead, also referred to as Channa argus, is a type of fish species that is able to breathe air. Although it is native to China, Russia, North Korea and South Korea, it can be found all over the United States. It prefers muddy ponds, swamps, and streams with temperatures ranging from 0-30 degrees Celsius. During a drought, it will bury itself in mud. The Northern Snakehead can survive up to four days out of water and can grow up to 33 inches long.
Therefore the Megladon fish is a laterally compressed fish which allows it to live in dense covers or coral reefs. Laterally compressed fish make the fish flattened side-to-side. The coral reefs of Jamaica are vibrant and full of fish. The Megladon's body shape is efficient enough to allow burst of speed, escape from predators as well as fit into small spaces. They have two pectoral fins that are forked in on the sides which enable them to control their direction of movement.
How does the adrenaline affect on the heartbeat of daphnia? Adam Stępień IIB Background information: Daphnia- they are small, planktonic crustaceans, between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Epinephrine (adrenaline) - is a hormone and a neurotransmitter.
They have been known to feed on fish, dolphins, whales and seals. Sharks prefer meals with a high fat content to give them energy. They are ambush hunters, taking their prey by surprise from underneath. They have been known to come up from the bottom so fast that their entire body has left the water. The Great White has only one natural predator, the orca.
(Eksp Klin Farmakol) According to The Scientific Method II (C.Gervasi-2010), as a crustacean, the daphnia is closely related to freshwater and brine shrimp, and more distantly related to a crab and lobster. The common name “water flea” comes from the jerky movement which they move through the water and their overall body shape. The daphnia’s bodies are almost transparent and with a microscope, the heart beating
These types of animals usually tend to live in a more stable environment because their internal body needs to match their external living environment. The second way animals can regulate their osmotic concentration is by being an osmoregulator. These animals are independently able to maintain their salt level in their internal tissues regardless of the external environment’s solute (Campbell, 2008). Most marine invertebrates are osmoconformers and for them to survive in a hyperosmotic environment, an osmoconformer which is hyperosmotic to the environment must discharge excess water (Campbell, 2008). If the environment was hyperosmotic then an osmoregulator must intake water in order to survive (Campbell, 2008).
