Slave Religion essays

Slave Religion essays When it comes to religion most people feel they have a belief in God or a higher power. This belief helps sustain them in times of mental and emotional turmoil and many times physical pain. The slaves of North America brought with them a belief in their sacred beings, in which they didnt distinguish the living from the dead. Their belief that in death the body just slips from the physical state to a spiritual one was widely believed in and can still be seen in such places as Jamaica and Trinidad, and in United States but to a lesser degree in the form of Voodoo. A religion that incorporates Because they were very expressive in their supplications to God in their practice of their religious beliefs, their prayer sessions were stifled by the slave holders for fear of slave revolts. Because of the censorship, they generally had to wait until late at night after the head count when they could slip away to a designated location (generally a predetermined slave house) or theyd steal a way into the woods for fear of being heard by their masters. When really concerned about their masters not learning of their prayer meeting (particularly their mid week meetings) to mute their voices they would turn pots upside down in the middle of the floor or the round area in the thickets that they had created for their prayer sessions. Some would even resort to putting pots over their heads because they were overcome with emotions and it was forbidden to worship without the masters approval. The African slaves brought with them the practice of laying of their hands on each other as they sang and prayed as a sign of physical support, understanding, and healing of the spirit. Their beliefs helped them survive the physical, mental, and emotional degradation of being humans in bondage. In the US during the first one hundred and fifty years the slaves were able to practice their religion almost unobs ...

Special Feeding Adaptations of the Seahorse

Special Feeding Adaptations of the Seahorse The seahorse is one of 54 different species of fish in the marine genus Hippocampus- a word that comes from the Greek word for horse. Only a small handful of species are commonly seen in tropical and temperate waters of both the Pacific and Atlantic Oceans. They range in size from tiny, 1/2-inch fish to nearly 14 inches in length. Seahorses are one of the only fish that swim in an upright position  and are the slowest-swimming of all fishes. Seahorses are generally considered to be an evolved form of pipefish.   How Sea Horses Eat Because they swim so slowly, eating can be a challenge for the seahorse. Further complicating things is the fact that a seahorse has no stomach. It needs to eat almost constantly because food quickly passes straight through its digestive system. According to  The Seahorse Trust, an adult seahorse will eat 30 to 50 times per day, while baby  seahorses  eat 3,000 pieces of food per day. Seahorses do not have teeth; they suck in their food and swallow it whole. Thus their prey needs to be very small. Primarily, seahorses feed on plankton, small fish and small crustaceans, such as shrimp and copepods. To compensate for its lack of swimming speed, a seahorses neck is well adapted for catching prey, reports Scientific American. Seahorses ambush their prey by hovering silently nearby, attached to plants or corals and often camouflaged to blend in with their surroundings. Suddenly, the seahorse will tilt its head and slurp in its prey. This movement results in a distinctive sound. Unlike their relatives, the pipefish, seahorses can extend their heads forward, a process that is aided by their curving neck. Although they cant swim as well as pipefish, The seahorse has the ability to stealthily reach out and strike their prey. This means that they can wait for prey to pass by their perch, rather than actively pursuing them- a task that is difficult given their very slow speed. The hunt for prey is also aided by the seahorses eyes, which have evolved to move independently, allowing them an easier search for prey.   Seahorses as Aquarium Specimens What about captive seahorses? Seahorses are popular in the aquarium trade, and there is currently a movement to raise seahorses in captivity to protect the wild population. With coral reefs in danger, the native habitat of the seahorse is also challenged, leading to ethical concerns about harvesting them from the wild for the aquarium trade. Further, captive-bred seahorses seem to thrive better in aquariums than do capture  wild seahorses.   However, efforts to breed seahorses in captivity is somewhat complicated by the fact that young seahorses prefer live food that must be very small, given the tiny size of the young seahorses. While they are often fed frozen crustaceans, captive seahorses do better when feeding on live food. An article in the journal Aquaculture, suggests that live wild- or captive-raised copepods (tiny crustaceans)  and rotifers are a good food source that allows young seahorses to thrive in captivity.   References and Further Information: Bai, N. 2011.
