The formation of the complex pattern is influenced by the neurons and two lobes of the cuttlefish brain. Studies indicate that the cuttlefish skin contains approximately ten million color cells, the color cells function in a pattern, when some are on other color cells are off. These alternative functions of skin color cells enable them to create a pattern required to confuse their predators. Besides, cuttlefish possess a pigmented organ known as the chromatophore. When it is stimulated the chromatophore produces black, red, brown and yellow colors (Mäthger et al.
Whale Sharks the largest fish in the world and are found throughout the warmer areas of the oceans. Whale sharks can reach to 18 – 40 feet long and weighing from 12 - 20.6 tons (Bradford A. 2016). As filter feeders, whale sharks eat mostly plankton and other small organism such as zooplankton, copepods, shrimp, phytoplankton, mollusks, and sardines. Whale sharks capture their food by swimming towards it with their mouth open which can get up to 4.9 feet wide and engulfing their prey that enters their mouth (Rafferty J.
The weight average of rainbow trout is about 3kg while individuals of rainbow trout can reach much heavier weights. Feeding habits: Rainbow trout are predators with varied diets depending on their life stages and availability of their natural diets. When they are young, rainbow trout will feed on small organisms such as zooplankton, and as they grow they feed on larval, pupal and adult forms of aquatic insects. They also eat fish eggs, small fish, crustaceans, mollusks, and insects. In vegetated habitats, rainbow trout often have the opportunity to eat terrestrial insects that fall into the water such as ants, beetles, and crickets.
Over time, waterfowl have developed numerous adaptations to exploit these habitats and their abundant food resources (Coluccy). The waterfowl species have been able to share the same wetlands without competing for the same food resources. They are able to eat many different types of vegetation and survive quite well. Waterfowl have several different feeding modes to satisfy their energy needs. These modes include dabbling, diving, grubbing and straining.
Description The Hammerhead shark is a long, odd looking animal. on average, they 11.5 feet long, and weigh about 1,000 pounds. The odd shaped head they have is called a cephalofoil, and it allows for 360o vision. The Hammerhead shark has very different physical features from most other sharks. Habitat The Hammerhead shark can be found throughout various places globally, and usually lives in warm tropical and coastal waters along continental shelves.
In the second paragraph in the article, it is stated that there is a dominant breeding pair, with zero to four non breeders, and size is the determining factor on which fish are the breeding pair. The female is the largest instead of the male, which is common in fish but not so common in mammals. According to the article, if the alpha female dies, the alpha male, the second largest fish, is the one to change sex to female, whereas the biggest non breeder grows and becomes the alpha male. This article shows that a trigger for sex change is the death of an alpha breeder, and what determines which fish undergoes the change is the fish who just so happens to be the largest. This article can be trusted because it comes from a peer reviewed journal, Nature, whose articles are submitted to reviewers who are experts in the field that the author is writing
To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales. A marine Biologists’ job is varied. It can involve working on a specially equipped research ship, diving to study marine life, and collecting marine samples. It can also
In my life I’ve been freshwater fishing and saltwater fishing many times in a variety of places. Throughout my experiences I’ve realized that a large amount of people consider all types of fishing to be the same, this is not true in many aspects. It can be divided into two categories: saltwater fishing and freshwater fishing. I’ve caught a 40 inch northern in Canada (freshwater) which is a big fish, and it only took me ten minutes to get it into the boat. However, I caught a 42 inch shark in Florida (saltwater) which took me 20 minutes to reel in, and that is considered a small fish.
They can be found in depths between 50 feet and 300 feet. Red Snappers are a heavily regulated species with a smaller population. The Red Snapper is considered as reef fish, meaning that they eat smaller creature from the reefs (Oceana). Which consist of smaller fishes, crustaceans, octopuses, squids (Oceana). Most adult Red
