Biologists Robin Seeley conducted an experiment in which she gathered periwinkle snail shells on Appledore Island and measures their thickness. The time period in which she has found the snails was before the inhabitation of the European green crab. Eighty years later, the shell thickness of the snails were measured again and recorded. This time, the inhabitation of the european green crab has increased significantly and the thickness of the snail shells has increased. She has concluded that when the crabs arrived on the island, they began to eat the thin shelled snails because their shells were easier to crack.

The profile of Pallarenda beach as shown in figure 1 is very typical of a North Queensland, medium energy beach. The lack of organisms present higher up the beach was due to the harsh conditions at low tide. Ghost Crabs, Ocypode quadrata, can survive these areas as a result of their adaptations (The Otter Island Project). The ghost crab burrows during the day and feeds at night to avoid the heat of the day (The Otter Island Project). These crabs can actively take up moisture from damp sand to wet their gills (The Otter Island Project).

Green crabs are found in shallow ocean waters and they have a preference for sheltered areas. They are an aggressive and territorial crab species (CBC, 2012). Although this species is known as the “green crab”, they are not always green. In fact, this species of crab can range from a variety of colors such as red, orange, brown, blue and yellow; the colors often depend on when the crab last exuviated. Due to the fact that green crabs cannot be distinguished solely by color, they are often confused with other crab species such as the rock crab. A few ways to distinguish the European green crab from other crabs is by 5 pointy spines which are located on the front end of the carapace on either side of the eye as cited by GOV, (2013) and 3 rounded lobes located between the eyes. European green crabs are also distinguished by their claws of different sizes and the way the tips of its back legs are pointed, flattened and hairy. A European green crab generally doesn’t surpass 4 inches (appx. 100 mm) and an average green crab is approximately 2.5 inches (appx. 63 mm) (Peters et al. 2004). Male green crabs typically range from 40-70mm whereas female green crabs ranged from 40-65mm. If these crabs, male or female, surpassed their average size they were classified as old adults (Yamada and Gillespie, 2008). The adult green crab can survive out of the water for

The tortoises weigh a lot, the crabs are extremely strong, and the fish come in many different shapes and sizes. This paragraph feels a lot like a zoo, filled with animals and wonders. The giant tortoises can weigh up to 250 kilograms. The giant tortoises are also herbivores. When they poop on the ground, a certain grass called “turtle turf” grows. The coconut crabs are another animal. Their claws are so strong, that they can crack coconuts. They can also be as long as a meter as well. They are usually out in the early morning and the evening because it isn’t as hot, which could make them cook in their shells. Fish and octopi live in the coral reefs. The fish can range from ferocious to snappers to butterfly fish. The giant groupers and the octopi lurk in every crack and crevice. The animals complete the island. From tortoises to crabs to birds. The turtles weigh 250 kilograms, and the crabs can crack coconuts. The animals are unique, beautiful, and interesting. If these animals don’t go extinct, Aldabra will be full of

Kathy Conlan is an expert in understanding the weird and wonderful world of marine creatures that live deep under the Arctic ice. She specializes in marine benthic biology and amphipod systematics.

She is past chief officer for Life Sciences in the Scientific Committee on Antarctic Research (SCAR) and is a judge for SCAR’s Martha T. Muse Prize for Science and policy in Antarctica, represents Canada for the Canadian Committee on Antarctic Research, taught at Huntsman Marine Science Centre and Students On Ice, mentors university students and gives speaches and “Show and tells” at the museum.

Beginning with the simplest one-celled organism, an extraordinary animal rose in the murky waters entitled to a non-comparable killing-eating machine. This organism has become nature’s most genuine and most successful creature that it has remained unchanged for over 250 million years. Nature finally invented the perfect king of the sea. This animal has given the sea it’s “living” adjective; in turn, it was entitled—the “great white shark.”

Therefore, sea otters play an indirect, yet vital role in the preservation of kelp forests. This in turn protects kelp forests and other macroalgae, which would have otherwise been depleted due to grazing by sea urchins. “Where sea otters abound so do lush kelp forests, and where sea otters are absent the habitat is typically deforested by hyperabundant sea urchins” (Soulé et al 1240). The significance of this interaction can be wholly surmised only when the importance of kelp forests is understood. “Kelp forests are a source of food and habitat for dozens of other coastal species” (Soulé et al 1240). Innumerable coastal marine organisms thrive on kelp forests, enhancing biodiversity of the region. Therefore, to maintain the diversity and richness of coastal marine ecology, sea otters should be preserved, who indirectly lead to the preservation of kelps.

Three years ago, the author took a trip to Delaware. As his family was walking on the beach they came across some horseshoe crabs mating. He wondered how they have changed. The type of horseshoe crab he saw along the beach was called “limulus polyphemus”. Limulus Polyphemus is not found in the fossil records. The fossil record for horseshoe crabs is deeper than 20 million years, and the

“They see something, walk up to it, pick it up, and maybe beat the crap out of it,” says Justin Marshall, referring to a commonly unknown creature called the Mantis Shrimp. This species often goes overlooked and unnoticed by most of the world and not just because it only grows 2-7 inches (“Peacock Mantis Shrimp” 1). Since it is such an unknown animal, many people do not know what it is or what makes it remarkable. How can the small mantis shrimp, a crustacean whose appearance is more like that of a clown than a ferocious beast, be worth noting in the different fields of science? They are more interesting than they seem. Mantis shrimp possess a vast array of fascinating physical features that set them apart from other sea-dwelling animals: their clubs

Within a few minutes of leaving Saltburn, we are walking along the cliff-top to Hunt Cliff. The cliff face hereabouts supports colonies of kittiwake, and during the breeding season, you will hear an unmistakable ‘kitti-wa-a-k’ call. Kittiwakes live out at sea feeding on small fish and squid, and they only come ashore to breed. In summer, swathes of wildflowers bathe the cliff top with colour. The coastal grasslands sustain the scarce dyer’s greenweed and three species of orchid, as well as other plants including sea plantain, spiny restharrow and wild carrot.

The 59-year-old author, Sy Montgomery, has written 20 books, each based on a specific research or expedition she has taken part in. Her studies, which she descriptively incorporates into her novels, have warranted her various book awards and acclaims. She plunges herself into the lives and mysteries of Earth’s wildlife in order to gain a further understanding of how particular organisms thrive in their wild, dangerous environments. Although Montgomery was no expert in the field of cephalopods, she quickly learned all she could about the intriguing invertebrates through fellow researcher, experts, aquarists, divers, and colleagues encountered throughout her studies about octopuses. Through diligent research via articles, studies, field

The Ocean is 70 percent of the earth’s surface, humans have explored less than five percent of the ocean, and is home to an innumerable amount of living organisms. One of its oldest inhabitants is the Cheloniidae dates back to the Triassic era, roughly 250 million years ago, (Wang et al., 2013). The Cheloniidae family has several subspecies the Eretmochelys imbricate, Caretta caretta, Dermochelys coriacea, Lepidochelys olivacea, and Chelonia mydas. While there are multiple endangered subspecies of the Cheloniidae; the endangered Chelonia mydas, commonly known as the green turtle, will be the focus of this paper. The paper will discuss the green turtle’s importance to its ecosystem, where they are most commonly found, importance to its ecosystem,

Lobsters are benthic organisms because they on the ocean bottom (Townsend, 2012). These animals are on the bottom of the seabed and do not swim as much as organisms that never touch the seabed (Townsend, 2012). In this case, epifaunal is a word to characterize that lobsters live on the seabed (Townsend, 2012). Lobsters do not burry themselves into the seabed, but instead hind under rocks for protection from prey (Townsend, 2012). In addition, the mobility of lobsters was designed to catch prey and the mobility of a lobster is used for a survival technique that is heavily influenced based on feeding styles (Townsend, 2012). Furthermore, feeding styles increase growth in a lobster therefore molting and temperature of ocean are also important to study (Townsend, 2012). Studies are trying to find correlations that climate change can be linked to molting patterns, or with more carbon dioxide in the water lobsters carbon shells could be impacted (Townsend, 2012). Surprisingly, after over twenty years of studying many lobsters researcher Dr. Jelle Atema has come up with a detailed explanation for lobster mating behaviour where female lobster does not have a shell (University of Maine, 2016). On the other hand, Dr. Robert Steneck debates technology is best used to understand the lifestyle of a lobster (Gulf of Maine Research

The Caribbean Spiny Lobster, a uniquely adorned decapod, is found in subtropical to tropical waters, inhabiting rocky crags to sponges to sea grass. A carnivorous species, they will feed on gastropods, sea urchins, worms, and crustaceans. In addition to this, they are also important aquatic scavengers, aiding in the process of decomposition of dead organisms that fall to the ocean floor (Kanciruk 1980). Commonly fed on by moray eels and nurse sharks, they play a significant role in the food chain for not only marine species, but for humans as well. According to the FAO Fisheries and Aquaculture Department, this is one of the most important Palinurid species that is harvested in American waters due to high demand (Holthuis 1991). The economic

The Uca genus is comprised of fiddler crabs. There are currently 120 different extant species found worldwide. The members of the Uca genus can be found near the Eastern Atlantic, Western Atlantic, Eastern Pacific, and Indo-West Pacific (Rosenberg, 2014). This review will focus on eight species found in the Continental US: Uca burgersi (Saltpan Fiddler Crab), Uca crenulata (California Fiddler Crab), Uca minax (Redjointed Fiddler Crab), Uca pugilator (Atlantic Sand Fiddler Crab), Uca pugnax (Atlantic Marsh Fiddler Crab), Uca rapax (Mudflat Fiddler Crab), Uca speciosa (Longfinger Fiddler Crab), Uca thayeri (Atlantic Mangrove Fiddler Crab).
