A heavy-bodied shark with a "typical" streamlined shape, the Caribbean reef shark is difficult to distinguish from other large requiem shark species. It usually measures 2–2.5 m (6.6–8.2 ft) long; the maximum recorded length is 3 m (9.8 ft) and the maximum reported weight is 70 kg (150 lb). The coloration is dark gray or gray-brown above and white or white-yellow below, with an inconspicuous white band on the flanks. The fins are not prominently marked, and the undersides of the paired fins, the anal fin, and the lower lobe of the caudal fin are dusky.
Like all sharks, the blacktip reef shark has exceptional sensory systems. From there keen sense of smell to having the ability to see in low light condition, these adaptation have made them prestige at tracking down there prey. Sharks also have an additional sixth sense where they can sense electromagnetic fields in the water. The ampullae of Lorenzini, located in the snout region, enable a shark to detect its prey without physically seeing it.
Although still abundant at Cocos Island and other relatively pristine sites, grey reef sharks are susceptible to localized depletion due to their slow reproductive rate, specific habitat requirements, and tendency to stay within a certain area. The IUCN has assessed the grey reef shark as Near Threatened; this shark is taken by multispecies fisheries in many parts of its range and used for various products such as shark fin soup and fishmeal. Another threat is the continuing degradation of coral reefs from human development. There is evidence of substantial declines in some populations. Anderson et al. (1998) reported, in the Chagos Archipelago, grey reef shark numbers in 1996 had fallen to 14% of 1970s levels. Robbins et al. (2006) found grey reef shark populations in Great Barrier Reef fishing zones had declined by 97% compared to no-entry zones (boats are not allowed). In addition, no-take zones (boats are allowed but fishing is prohibited) had the same levels of depletion as fishing zones, illustrating the severe effect of poaching. Projections suggested the shark population would fall to 0.1% of pre-exploitation levels within 20 years without additional conservation measures. One possible avenue for conservation is ecotourism, as grey reef sharks are suitable for shark-watching ventures, and profitable diving sites now enjoy protection in many countries, such as the Maldives.
Like many sharks, the Caribbean reef shark mainly eats bony fishes. The shark uses six keen senses to locate its prey: olfactory, visual, tactile (including water vibration sensitivity through a lateralis canal system), auditory, gustatory, and electric reception. The Caribbean reef shark is especially adapted to detecting low frequency sounds (indicative of a struggling fish nearby).
The Reef story started 25 years ago when two brothers from Argentina Fernando and Santiago Aguerre acted on an idea to produce high quality, comfortable yet stylish sandals. Inspired by their love of the California lifestyle and surfing culture, the brothers moved to California in the early 80's and found Reef sandals. With a tiny amount of start up capital of $4000 and after lots of hard work Reef is now widely considered to be the number one sandal brand in the world.
One of Bermuda’s favorites, the Reefs Resort and Club is a classic retreat tucked along the island’s celebrated South Shore. Family-owned and operated by the Dodwells, their passion for island living is reflected in the love guests have for the resort and how often they return. Named #1 in the region by Conde Nast readers, this inviting hideaway perfectly captures the essence of Bermuda and the cherished traditions that make it a mecca for families, honeymooners and golf enthusiasts.
A reef is a bar of rock, sand, coral or similar material, lying beneath the surface of water. Many reefs result from abiotic processes (i.e. deposition of sand, wave erosion planing down rock outcrops, and other natural processes), but the best known reefs are the coral reefs of tropical waters developed through biotic processes dominated by corals and coralline algae.
