that stick out from their chins like whiskers. These barbels help the catfish find crabs, fish and shrimp in the muddy bays where they live. The dorsal and pectoral fins each are supported by a sharp, slime-covered barbed spine. The catfish is covered in a mildly toxic slime, that causes severe pain, and swelling, should the catfish cut you. The dorsal spine normally is held erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Adults may reach two

half visible, have four fins in view, with their dorsal fins displaying a separation above their gills. Altogether, there are three separate types of fish, with two of them both displaying brown stripes, and all three of them are grey in color. The main thing that distinguishes the different types of fish are their body structures. The fish along the bottom of the ocean are smaller and oval in shape while the ones above the primary turtle are larger in size with tail fins that are arrow

Animal Cruelty and Captivity Zoos, aquariums, and circuses do not treat animals with respect or civility. They inevitably suffer from diseases, pain, starvation, and fear so they will perform seamlessly for the public. Owners force their pets to carry out pointless tricks and performances and are almost always deprived of their normal behavior. Workers within the facilities that the animals occupy rip them from their natural habitat, beat submission into the performing animals, and deprive them

body (FLMNH). The body shape is elongated and possesses a fusiform shape, meaning it is wide in the middle and tapers at both ends; it also possesses a bilateral symmetry. There are two dorsal fins present, the first consisting of around 14-16 spines. There is a small gap in between the two fins, and the second fin is

It is hard to imagine a life without the childhood trips to the zoo, the circus, and other animal based attractions. It is even harder to imagine a daily life without digging in to a hamburger and washing it down with a cold glass of milk. It is almost impossible to imagine a life where one does nothing wrong, but it subject to abuse and torture for selfish purposes of another species. Animal exploitation is a common yet overlooked practice all around the world. Helpless animals are poked, prodded

Dolphins, like most all sea animals, have fins that help them to swim quickly and steadily. They have three different types of fins on their bodies. They are called Pectoral Fins, a Dorsal Fin, and Flukes. Pectoral Fins are to the dolphins what arms are to us. They are situated around where arms would be on a dolphin and these fins help the dolphin to steer in the water. The Dorsal Fin is attached to the top of the dolphin. This stabilizes the dolphin while it swims

For several years, Americans have been visiting amusement parks, like SeaWorld and Six Flags, to observe large animals like orcas, also known as killer whales. These whales are quite difficult to view in the wild, but can now be seen for a simple fee. Orcas are known to be one of the smartest mammals. They are friendly, and this has caused people to take advantage of them. For the past sixty years, people have brought these massive creatures into their aquariums to make a profit from their exhibitions

The topic of zoos and whether or not they’re humane have quickly become one of the biggest controversial topics in the past twenty years. There is not much of a ‘middle’ perspective in this debate, rather people tend to lie on two completely opposite ends of the spectrum when displaying their beliefs pertaining to the zoo debate. I chose to research this topic because though I have strong beliefs, I think that, on this matter specifically, people often jump to a certain side without any prior research

"People always wonder whether I believe SeaWorld should be closed down. I always say no. They have tremendous financial resources and could play a key role in creating sea sanctuaries which could be a profit-making endeavor. I believe people would flock to a site where a killer whale is being a killer whale for the first time -- something infinitely more satisfying than seeing a killer whale dance the Macarena." - Gabriela Cowperthwaite. Cowperthwaite, the director of the documentary film Balckfish
