Fish anatomy

The internal and external anatomy of Labeo umbratus Hannah Janse van Vuuren Abstract The anatomy of an Labeo umbratus specimen, found in the Krugersdrif dam, was studied. Annotations of the positions of the internal organs as well as the external morphological characteristics were made. Upon further analysis, several characteristics were identified that would have eased life in aquatic environments. Some of these characteristics include, sensory receptors located on the head as well

queue raide (French), carachana (Spanish), falscher bonito (German), thunnin (Danish), tunnin (Norwegian). Family: Scombridae (Tuna & Mackerel) Description The little tunny, Euthynnus alletteratus, is a common species of tuna and a popular sport fish inhabiting the Atlantic. Relatively small in size, the little tunny may grow to be a meter in length, although they are often much smaller. This species can weigh up to 12 kg, but, as stated with their length, tend to be much smaller (Robins, 1986)

gases, electrolytes, nutrients, wastes material and regulatory substances. Lymph is the part of plasma that perfuses out of the capillaries to both the tissue. It also contains cellular components; particularly more lymphocytes. The study on blood of fish dates as far back as 1920. Hall and Gray [1929] have given the concentration of haemoglobin iron in few teleosts, and elasmobranch showing that the elasmobranchs have lesser concentration, Vars [1934] reported the values of iron, blood sugar, RBC Count

can be a little ridiculous. Its between the 3-inch snail darter fish and then whether to build the Tellico dam. The main eye attention to this argument is whether we should let the snail darter fish live or not. If we build the Tellico dam to snail darters will die. On the other hand its a big deal because the snail darters are on the endangered species list. In my opinion I'm on the snail darter fish side because I think the fish should live. The cost to build the dam is eighty million dollars

water fish and saltwater fish are fully aquatic animals. Fully aquatic mean that both freshwater fish and saltwater fish will die shortly if they are taken out of water (Anderson et al, 2016).. Like most vertebrae, fish primarily require oxygen for metabolism. However, fish cannot obtain oxygen from air directly. Fortunately, water contains significant amount of dissolved oxygen. Fish obtain their oxygen from water through their gills (Grantly, Hastings & Walker, 2015). Both freshwater fish and saltwater

barbels that stick out from their chins like whiskers. These barbels help the catfish find crabs, fish and shrimp in the muddy bays where they live. The dorsal and pectoral fins each are supported by a sharp, slime-covered barbed spine. The catfish is covered in a mildly toxic slime, that causes severe pain, and swelling, should the catfish cut you. The dorsal spine normally is held erect when the fish is excited and a tennis shoe or even a leather-soled shoe offers little protection. Adults may reach

Great White Shark Ocean Life The Carcharodon Carcharias, or more commonly known as the Great White Shark, is the outspoken king of the ocean. They are a nektonic organism. Every organism has a full biological classification. The Kingdom is Animalia, the Phylum is Chordata, the Class is Chrondrichtyes, the order is Lamniformes, the Family is Lamnidae, the Genus is Carcharodon, and the Species is the Carcharias. The Great White Shark has a robust, torpedo shaped body, a hefty, conical snout. It has

Blacktip Reef sharks are unique organisms that appear as the way their name describes it. The sharks have black tips on its caudal and dorsal fins, as well as angled saw-like teeth and a round and small snout. Other fins that this fish has is its two pectoral fins, pelvic fin, and an anal fin. These sharks can grow to be six to seven-feet long and have white bellies and dark backs, this allows the shark to disguise itself with the obscured seafloor and the lighter ocean surface. Blacktip Reef sharks

talk about specific kinds of biomimetic robotics, CALibot and Tumbler robotics . CALibot Abstract CALibot is the most naturally swimming robotic fish in the world. and is a biomimetic CAlibot with actuated pectoral fins and actuated caudal fin for propulsion for turning and dynamic lift. 2D velocity fields around a free swimming freshwater 2 black shark fish in transverse (YZ) longitudinal and plane (XZ) are measured using digital particle pic velocimetry (DPIV). By transferring momentum to fluid, thrust

Understanding the biology of early life history stages of fish is essential for effective fisheries management (Mwaluma et al., 2014; Hames Hichford, 2005). For example, knowledge in fish development such as ontogenetic intervals and embryonic and larval development of fish species is a prerequisite to set the policies for their conservation and stock enhancement through larviculture (Rahman et al, 2009; Yanes-Roca et al., 2012; Amini et al., 2015; Andrade et al., 2016). Furthermore, the mechanisms
