Tasseled Wobbegong Shark Facts

Tasseled Wobbegong Shark Facts The tasseled wobbegong shark is one of the most extraordinary-looking shark species.   These animals have distinctive, branched lobes extending from their head and a flattened appearance. Although these sharks were first described over 100 years ago (1867), they are not well-known.   Tasseled Wobbegong Shark Identification Like other wobbegong sharks, tasseled wobbegongs have large heads and mouths, flattened bodies and a spotted appearance.   These sharks have 24 to 26 pairs of highly branched dermal lobes that extend from the front of the sharks head to its pectoral fins. It also has branched nasal barbels on its head.  This shark has patterns of dark lines over lighter skin, with dark spots and saddle patches.   Tasseled wobbegongs are usually thought to grow to a maximum size of about 4 feet in length, although a questionable report estimated one tasseled wobbegong shark at 12 feet. These sharks have three rows of sharp, fang-like teeth in their upper jaw and two rows of teeth in their lower jaw.   Classification: Kingdom: AnimaliaPhylum: ChordataClass: ChondrichthyesSubclass: Elasmobranchii Order: Orectolobiformes Family: Orectolobidae Genus: EucrossorhinusSpecies: dasypogon   The genus Eucrossorhinus comes from the Greek words eu (good), krossoi (tassel) and rhinos (nose). Where Do Tasseled Wobbegong Sharks Live? Tasseled wobbegong sharks live in tropical waters in the southwest Pacific Ocean off Indonesia, Australia and New Guinea. They prefer shallow waters near coral reefs, in water depths of about 6-131 feet.   Feeding: This species feeds at night upon benthic (bottom) fish and invertebrates. During the day, tasseled wobbegong sharks rest in sheltered areas, such as in caves and under ledges. Their mouths are so large, the tassseled wobbegong sharks have even been seen swallowing other sharks whole. This shark can feed on other fish that share its caves. Reproduction: The tasseled wobbegong shark is ovoviviparous, which means that the females eggs develop within her body. During this process, the young get their nourishment in the womb from the egg yolk. Pups are about 7-8 inches long when born.   Shark Attacks: Wobbegong sharks are not generally considered threatening to humans, but their ability to camouflage with their environment, combined with sharp teeth, can result in a painful bite if you come across one of these sharks.   Conservation: These sharks are listed as near threatened on the IUCN Red List, Threats include damage to and loss of their coral reef habitat and overfishing.   Not much is known about this species, but populations appear to be declining, which is another reason for their near threatened listing.   Because of their beautiful coloration and interesting appearance, these sharks are sometimes kept in aquariums.

Past-Tense Regular Verb Pronunciation Guide

Past-Tense Regular Verb Pronunciation Guide A language thats always changing and adding new words, English is a challenging one to learn, as it is full of quirks and exceptions. The construction of regular past-tense verbs, at least, is pretty straightforward. It is generally done by adding -d or -ed to the verb, and it doesnt change form based on the subject of the verb: I asked, he agreed, you accepted- the verbs in these instances all look alike, ending in -ed. What does differ between them, though, is the  pronunciation of the ending. For some verbs, its a voiceless sound like T, as in asked; in some, its a voiced sound of D, as in agreed; and in some, its pronounced like ID, as in accepted. The lists that follow are three groupings of regular past-tense verbs, based on their pronunciation of the ending.   Note:  When you are looking at sentences to find the verbs to change to past tense, be certain you have found the verbs.  Theyre the action words. Group A:  Voiceless Last Sound of the Infinitive If the infinitive of the verb has a voiceless sound at the end of it, such as p, k, s, ch, sh, f, x, or h, you pronounce the ed ending as a T. (Note the pronunciation in parentheses. Its the sound that determines the group that a word belongs to, not always the written letter. For example, even though dance ends with a -ce, its sound is that of an s, so its in this voiceless group.) Example: Ask, asked ask(T) -ed as â€Å"T† askedbakedbrushedcookedcrackedcrasheddanced (da:ns) tdresseddroppedescapedfinishedfixedguessedhelpedhikedhopedjokedjumpedkissedknockedlaughed (là ¦f) tlockedlookedmissedmixedpackedpassedpickedpressedpronouncedpushedrelaxedshoppedslippedsmokedstoppedtalkedtypedwalkedwashedwatchedworked Group B:  Voiced Last Sound of the Infinitive If the last sound in the  verb is a voiced one, such as in l, v, n, m, r, b, v, g, w, y, z, and vowel sounds, or diphthongs, then pronounce the -ed ending as D. (Note the pronunciation in parentheses. The sound determines the group that a word belongs to, not always the written letter. For example, even though advise ends with an -se, its sound is that of the voiced z sound, keeping that word in this voiced sound group.)
