Diet This nocturnal hunter feeds on bony fish, small sharks and rays, octopus, and large crustaceans. Unique Adaptations Sand tiger sharks are often found in groups of a few dozen, hovering in caves or near reefs or shipwrecks.
Sand tigers migrate, coming toward shore during the summer and moving southward or to deeper waters in the winter. Reproduction Female sand tiger sharks are viviparous (producing living young from eggs that hatch within the body).
Southern stingrays inhabit temperate waters of bays and estuaries from New Jersey to Brazil, as well as the Gulf of Mexico. Diet Rays feed on a wide variety of bottom organisms, such as crustaceans (shrimp and crab), mollusks (snails and shellfish), and worms.
Development is viviparous (pups hatch from their egg capsules while inside the mother’s uterus and are born soon after). In the early spring and summer, females may leave the water and return to their home beach to nest.
Kemp’s Ridley sea turtles are carnivores, feeding on crabs, mollusks, jellyfish, mussels, and fish. Unique Adaptations Streamlined bodies and flippers make these large animals powerful swimmers and divers-some species routinely diving to depths greater than 1,000 feet and staying underwater for several hours.
Unlike their freshwater relatives, sea turtles have a special gland that rids their bodies of excess salts. These events are called an “arrived” and take place on a small strip of beach at Ranch Nero, Mexico.
Their populations have declined due to commercial harvest of turtle meat, eggs, skins for leather, and shells for ornaments and jewelry. They die from ingesting marine debris, such as plastic bags, or get caught in nets as by catch and drown.
Moray eels are found in tropical reefs and shallows from New Jersey to Brazil, including Bermuda and the Gulf of Mexico. They feed on fish and crustaceans, especially crabs, and use their long, slender bodies to enter holes and crevices in search of hidden prey.
Despite warning predators with a large open mouth and sharp teeth, morays are not aggressive and do not usually bite unless provoked. Moray eels begin adult life as males, then later change to females (sex reversal).
Cobra can be found on the western coast of the Atlantic from Massachusetts to Argentina, often in open waters. They frequently follow large animals like sea turtles, sharks, and rays to scavenge leftovers.
They live in the tropical and temperate waters of the Atlantic Ocean, along the eastern coast of the U.S. and south to Brazil and Uruguay. Jacks are typically light, usually silver with red pigmentation which disappears in dark ocean water.
Diet These strong-swimming carnivores rely on speed and strength to catch their prey, which includes small fish, cope pods, and other ocean animals. Unique Adaptations Jacks are often found swimming with sharks, but when roaming the open sea they school as a defense mechanism.
Jacks can also be seen hitching a free ride in the bow wake of their predatory “companions.” Juveniles hide among jellyfish, debris, plants, etc, and have a deeper and sleeker appearance then the adults. They prefer the sheltered habitats of coral reefs, and especially shady areas such as shipwrecks, rock ledges, and caves.
Atlantic goliathgrouper have a broad, flat head and mouth, and can grow up to 8 feet long and weigh over 700 pounds. These hunters are not built for speed over long distances and prefer to ambush prey, rather than pursue it in open water.
The diet of these large predators consists mainly of crab, lobster, fish, octopus, and young sea turtles. Habits and Adaptations Atlantic Goliath groupers are often spotted or dark, allowing them to camouflage with their surroundings.
Small groupers may be preyed upon by barracuda, king mackerel, moray eels, and sharks. When threatened, an Atlantic goliathgrouper will defend its territory with aggressive body language and a distinctly audible rumbling sound.
These puffer fish primarily inhabit coral reefs and other warm shallow waters. Usually brown, with some yellow on the underside, these stocky, slow swimming fishes have a large head and a “box-shaped” body.
Diet Porcupine fish use their strong beaks to crush coral polyps, mollusks, crustaceans, crabs, and sea urchins. Unique Adaptations Puffers hide in coral and as their name implies, can puff up two to three times their normal size by sucking air or water into a special chamber in their abdomen.
Puffers employ a number of defenses to avoid getting eaten: they are covered with sharp spines, their internal organs contain an extremely toxic nerve poison, and when cornered they can bury themselves in the sand. This important food fish can be found in warm coastal waters, from Massachusetts to Brazil, including Bermuda and the Gulf of Mexico.
They have a triangular-shaped head and a notched tail, and are capable of inflicting injuries to unsuspecting fishermen with their well-developed teeth. Predators approaching from the bottom see a white belly that blends with the bright ocean surface above.
Tarpon are found in tropical and temperate waters along the eastern Atlantic coasts of North and South America. Unique Adaptations When swimming in oxygen-poor water, tarpons can gulp air from the surface using special lung-like bladders.
Initially the young head to shallow water where they become an intricate part of the plankton that drifts with ocean currents far from shore. Trigger fish usually spend a large portion of their lives near a coral reef-inhabiting areas in coastal waters from New York to Brazil.
Small eyes set high on a large, angular head and jaw give them a “bucktoothed” appearance. Diet Trigger fish have powerful jaws and teeth that allow them to easily crush hard-shelled prey like crustaceans, mollusks, coral, and sea urchins.
The Queen trigger fish will blow mouthfuls of water at sea urchins to flip them over and expose their softer underparts. The Atlantic goliathgrouper, like most groupers, is an ambush predator and eats fairly large fishes and invertebrates and even small sharks.
Throughout most of the year, low numbers of the Atlantic Goliath groupers are observed in any one place. However, during reproduction (immediately after the full moons between June and December), they come together in groups of at least 100 individuals.
These groups are known as spawning aggregations, and they form at relatively few places throughout the species’ range. Though they were likely naturally rare, scientists believe that destructive fishing practices have reduced the numbers of the Atlantic Goliath groupers by at least 80% and that the species is now critically endangered.
These fish utilize the same, few locations and same, few days for spawning every year, so their presence is quite predictable. Furthermore, a total lack of fear of people makes them an easy target for spear fishers.
Finally, the Atlantic goliathgrouper ’s large size, slow growth, and ease of capture all contribute to slow its recovery, even where laws have been put in place to give it some or complete legal protection from fishing (e.g., in the USA and Brazil). It is important to continue to monitor Atlantic goliathgrouper population trends in order to determine whether the species is recovering or if stronger legal protection may be required.
The two species are similar in both appearance and behavior, but little is known about the population trends or conservation status of the Pacific goliathgrouper. Groupers are generally a friendly species and can be found patrolling artificial and coral reefs alike, primarily in shallow tropical waters.
Goliath groupers navigate to an annual spawning for breeding, the season and location varies depending on the population. In Florida, hatchlings join their brethren in safe spaces near coastal mangrove estuaries and spend their first six years of life dining exclusively on fish, crabs, and shrimp before heading out to open waters.
The Goliath grouper grows slowly, attaining maturity around age 20-25, which is why it is important to manage fishing of the species; they need the chance to reach adulthood to reproduce in order to create a sustainable fishery. The Goliath grouper is a key species in Florida waters because their presence is an indicator of health for local coral reefs.
This particular species feeds by swallowing their prey whole, creating negative pressure that quickly them to bring in whole invertebrates, fish, and even smaller sharks. Many grouper, manatees, and turtles were found washed ashore on Southwest Florida beaches during the red tides in 2003 and 2005.
The good news is that as of 2006 the Goliath grouper ’s population had improved and was considered to be on a recovery trajectory due to the careful protection by NOAA Fisheries. The Goliath bird eater, with the scientific name of Therefore blonde, is the king of spiders that inhabit northern South America upland rainforests.
In addition to this, the Goliath bird eater family is Tarantulas and are the largest arachnids on this planet. The Goliath bird eater weight is only 0.38 pounds, thus having a leg span of up to twelve inches.
Their location includes under rocks and roots, silk-lined burrows, and deep rainforests. The terrestrial Goliath bird eaters appear to live in the Amazon rainforests, marshy or swampy areas, and deep burrows.
Furthermore, these spiders dig holes in the moist and soft soil, thus hiding within them. Like all other animal species, these spiders also require a proper diet for their survival.
The Goliath bird eater diet also includes giant insects, amphibians, worms, snake, cockroaches, and small vertebrates. These tarantula species have bad eyesight, unlike other jumping spiders.
By choice, they depend upon their modified leg hairs, vibration-sensitive, for warning them about the danger. These spider lings undergo the molting process for growing and become sexually mature at the ages of two to three years.
The Goliath bird eaters are eaten by some of its natural enemies, i.e. snakes, wasps, and other tarantula species. In addition to this, small insects can also kill them very quickly during the molting process when they are fragile and cannot move well.
Researches have shown that they do not use their venom son humans but sometimes can bite due on threatening. Although their long fangs can easily get penetrated to human skin, the death will not occur.
Some exciting Goliath bird eater fun facts include that their bodies’ hair can cause severe irritation to humans’ skin. Furthermore, they can quickly regenerate their lost limbs or body parts by the process of molting.
The male ones appear to die after fulfilling their biological functions and mating with females. They detect prey’s presence by sensing their vibration on the ground and usually hunt at nighttime.
The Goliath bird eaters also produce hissing sounds by bristles rubbing on their legs together for frightening the intruders or other predators. These spiders also appear to throw off barbed hairs from their abdomen during the alarming situations.
The Goliath bird eaters can be made as good pets to only those people who have some experience to adopt them. Also, due to their large fangs and other characters, there must be proper research before buying them as pets.
The Goliath bird eater care sheet also includes that they should be feed with larger insects, cockroaches, and locusts. Sometimes the people get confused and raise some questions about these spiders even after knowing the interesting facts and information about them to make their minds clear.
These bird eaters rely on birds, locusts, toads, rodents, lizards, snakes, small vertebrates, and other invertebrates to survive. Researches have shown that cockroaches make a considerable proportion of their diet in the wild.
Although some of them have developed unique behavior patterns, they still do not know about the personalities’ definition. As we have discussed many exciting facts and information about these tarantula species, they also do biting to humans.
These Goliath bird eaters also have some predator threats, i.e. snakes, lizards, toads, rodents, and small vertebrates.
