Clownfishing Mating Essay Example | Topics and Well Written Essays - 2000 words

Clownfishing Mating - Essay Example The fish thrive in the warm waters of the tropics (Maddern 1990 p 36). They are mainly found in the salty waters of the Indian Ocean and the Pacific. The excretion from the fish is a major source of nourishment for the sea anemone that absorbs the nutrients emanating from fecal matter. More over, the movements of the Clownfish in the water surrounding the sea anemone, especially when fanning the eggs are significant for water circulation, which is significant for the distribution of nutrients for the nourishment of the sea anemone (Drury 2008 p 63). The Clownfish is covered by a mucus coating around its body which as Wittenrich et al. (2007 p 93) observed are derived from sugars, which is one of the factors that prevents the stinging reaction of the sea anemone as the nematocysts are triggered by the presence of protein based substances in the surrounding. The fish dwell in one sea anemone as a group, which means that several sea anemones will host different groups of fish (Godwin 1994 p 561). In other words one sea anemone is the territory of one small group of fish. Clownfish is one of the aquatic organisms whose sex remains a subject of controversy. It is generally known that the fish is capable of switching its sex. This essay is a critique of the Clownfish mating process and gender changes that occur, as well as an exploration of the different species. The ability to switch sex is one of the aspects that make the fish unique especially the fact that this can happen to any adult fish. Kuwamora & Nakashima (1998 p 126) observe that during hatching, the fish are usually one sex, i. e, all males. The dominant male that becomes larger than all the rest during adult stage develops in to a female. None other develops in to a female so long as the dominant female is alive. The fish that follows in terms of size becomes the dominant male, while the rest remain small

Children under 12 Should not Be Introduced to the Internet Essay

Children under 12 Should not Be Introduced to the Internet - Essay Example For this reason, researchers and scholars have not hesitated to state that the internet has become an integral part of the contemporary world. However, science and technology comes at a cost (Staples, 2008, p. 288). The internet causes more harm than benefit to children. Efforts to control activities and content of the internet to children have proved futile since the internet does not belong to any company or state. This paper delineates the dangers that internet poses to children both in social and academic activities. It discovers the risks associated with unsupervised internet use by children. Conspicuous chat rooms, instant messaging and explicit contents are the intermediates that make smooth the progress of the fundamental issues and problems within this topic. In addition, this paper discusses the role of the parents in ensuring their children’s safety in the internet. Unsupervised access to the internet by children under the age of 12 exposes the child to a world of d etrimental dangers that are both physically and psychologically abusive (Livingstone, 2009, p. 23). Arguably, the content in the internet posses a higher danger and risk to children than movies, music and television. Chat rooms and social media have become the areas of interest in exploring the risks exposed to children. In the recent past, cases of abduction, murders and physical and sexual abuses on children have been on the increase. National Centre for Missing and Exploited Children (2005, p. 2) has linked the internet as the major cause of these evils. The report notes that 89 percent of sexual solicitations or approaches occur in the internet annually and that 29 percent of all the children who use the internet have been sexually victimized. In addition, the report suggests that 31 percent of girl children have been sexually harassed in a chat room. Debatably, National Centre for Missing and Exploited Children (2005, p.13) reported in a research, that more than 4 million child ren between the age of 7 and 17 who use the internet have a higher probability of giving out their home address and their email addresses. It has been reported that 29 percent of all the children under the age of 12 who use the internet would give out their home address if asked while 14 percent would give out their email address if requested (National Centre for Missing and Exploited Children, 2005, p. 14). This has been the primary contributor of child abductions and murders. Reports indicate that children have opted to turn to the internet where their social life cannot be known by their parents. The internet permits private and real time conversations. This has made children succeed in safeguarding and protecting their social life from scrutiny by the parents and adults (Staples, 2008, p. 288). However, this has had more harm than benefit. Children spend a lot f time in the internet and are disconnected from the societal happenings that have for long equipped adolescents into ad ult hood (Strasburger & Wilson, 2002, p. 134). Though researches have portrayed the internet as a revolutionary method of supplementing people’s social lives and civic connections, it has replaced head to head connections with friends and family members. For this reason, the internet has left the youths with no social skills. Staples (2008, p. 289) notes that they
