Lagocephalus Sceleratus
''Lagocephalus sceleratus'' (Gmelin, 1789), commonly known as the silver-cheeked toadfish, or Sennin-fugu ( ja, 仙人河豚), is an extremely poisonous marine bony fish in the family Tetraodontidae (puffer fishes). Habitat and distribution The species is common in the tropical waters of the Indian and Pacific oceans. In the Mediterranean Sea, it is an invasive species likely introduced via Suez Canal. It has been caught off the coasts of Israel, the south of Turkey, in Cyprus, the south coasts of mainland Greece, Crete, and Rhodes. In 2013 it was reported off the waters off Lampedusa Island in the central Mediterranean, and in 2015 off Malta and also in Montenegro, southeastern Adriatic Sea. Currently the westernmost record is from the Strait of Gibraltar. Greek authorities sent out an alert about the fish. A few days before 9th of February 2022, a specimen was caught by Croatian fishermen near the island of Pašman in the Adriatic with the Croatian Institute of Oceanography ...

Pašman
Pašman () is an Adriatic island off the coast of northern Dalmatia in Croatia with an area of 60.11 km2, located to the south of Zadar, surrounded by the islands of Ugljan to the northwest, Iž to the west, and Dugi Otok and Žut to the southwest. The island is inhabited by 2,845 people, according to the 2011 census. There are 10 settlements on the island; Ždrelac, Banj, Dobropoljana, Neviđane, Mrljane, Barotul, Pašman and Kraj, belonging to the Municipality of Pašman, and Ugrinić and Tkon, belonging to the Municipality of Tkon. Among all islands in the Croatian archipelago it is Pašman that has the biggest green surface considering its total area. It is the 12th largest island in the archipelago by land area. It is also known to have the cleanest water in the Adriatic due to the constantly changing currents. History In addition to rare Stone Age finds, many Bronze and Iron Age fortifications confirm the early settlement of the island. Roman writers count ...

Fish Described In 1789
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Tetrodotoxin
Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish and found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails), it is actually produced by certain infecting or symbiotic bacteria like ''Pseudoalteromonas'', ''Pseudomonas'', and ''Vibrio'' as well as other species found in animals. Tetrodotoxin is a sodium channel blocker. It inhibits the firing of action potentials in neurons by binding to the voltage-gated sodium channels in nerve cell membranes and blocking the passage of sodium ions (responsible for the rising phase of an action potential) into the neuron. This prevents the nervous system from carrying messages and thus muscles from contracting in response to nervous stimulation. Its mechanism of action, selective blocking o ...

Pelagic Zone
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Lagocephalus Lagocephalus
The oceanic puffer, sci-name: ''Lagocephalus lagocephalus'' (meaning "rabbit head"), is a pufferfish of the family ''Tetraodontidae Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfis ...'', found in all tropical and subtropical oceans, at depths of between 10 and 475 m. Though indigenous to the Pacific, Atlantic and Indian oceans as well as the Sea of Japan, a surge in its distribution throughout the Mediterranean Sea has been reported in years of recent. Its length is up to 61 cm. It is thought to be responsible for fatal poisoning and should therefore not be eaten.
