limbatus and C. tilstoni, suggesting that these species are very closely related and that they only diverged from each other approximately 200,000 years ago (Wong et al., 2009). The presence of CO1 haplotypes shared between C. limbatus and C. tilstoni also suggest the two shared a recent common ancestor and thus may explain why analyzing CO1 results of the two species resulted in our ambiguous BOLD Systems results (Boomer et al., 2010). Similar research into C. obscurus indicate that it is very similar genetically to Carcharhinus galapagensis (Galapagos shark), suggesting that the two derived from a common ancestor very recently as well and this may explain why it was difficult in definitively distinguishing between the four samples (Benavides et al., 2011). These ambiguity issues could perhaps be circumvented in future experiments by sequencing other genes in addition to the mitochondrial CO1 gene when identifying shark…

WHERE DOES BLACKTIP REEF SHARK LIVE? Blacktip reef shark (Carcharhinus melanopterus) DESCRIPTION The blacktip reef shark not the same as blacktip shark (Carcharhinus limbatus), though they possess similar attributes but also different species of shark. The blacktip reef shark is famous for the black tips on its fin which also makes it to be easily identified, also known as black wing shark. As its name says, blacktip reef shark's pectoral fin tip and dorsal fin are black, while the lower part…

Dumbo Octopus-Grimpoteuthis Found in the deep sea pelagic zone these octopi propel themselves upward with ear-like fins. These creatures use their arms or tentacles to move in different directions. They prey on various crustaceans for food. Oceanic Whitetip Shark- Carcharhinus longimanus Found in the pelagic zone, these dominate feeding frenzy sharks are aggressive predators towards various fish and shipwrecks. They are commonly found accompanied by the pilot fish. They are endangered by…

The Blacktip Reef Shark is native to the tropical coral reefs of the Indian and Pacific Oceans. The Blacktip is listed under kingdom animalia, phylum chordata, class Chondrichthyes, order Carcharhiniformes, family Carcharhinidae, and genus Carcharhinus. This shark was given its name based off of the blacktip at the end of its dorsal fin. This fin appears very vivid in the shark’s youth, but fades with age. The Blacktip Reef Shark will most likely grow to be 4.9 feet and weigh roughly 40 pounds,…

in the ecosystem. To improve water quality, sea grasses trap sediments and particles in the water column which create cloudy water, while acting as a filter for nutrients which come from storm water run-off and industrial waste. The extensive and long length of the sea grass’ leaves provides a habitat for many small marine animals to hide from predators. The animal that I have chosen is the bottlenose dolphin. Structural adaptations Bottlenose dolphins have a streamlined fusiform body which…
