Each species in the world have a specific job in our world, a niche, some species are important and get the title keystone. Keystone species have an important life, without them the ecosystem they live in will have a domino effect that will change the ecosystem or destroy it all together (Nancy, 2013). The Sea Otter (Euhydra lutris) are remarkable creatures in that they help keep their environment in check (Konar, 2000). The genus name Euhydra and the specific name lutris are both translated…

Scales are the exoskeleton covering of the fishes found in most of the cartilaginous and bony fishes which provide protection to the body. Scales are small, thin, cornified, calcareous or bony plates which fit closely together or overlap. Scales are complex derivatives of the integument and are derived from the mesenchymal cells of the dermis. They vary greatly in size, shape, structure, and extent, ranging from rigid armour plates in fishes such as shrimp fishes and box fishes, to microscopic…

Coelenterata - Characteristics of coelenterata are as follows: Coelenterata are creatures that live in the sea although there are some who live in fresh water.Coelenterata included in the class of diploblastik. Exterior body composition has epidermal cells and in the inner layer of gastrodermis. Coelenterata have a difference compared to the porifera where although equally hollow but coelenterata has only one hole for all activities such as eating and as a disposal. Another feature is on the…

Scuba Diving in Tarkarli - Read before you dive By: Mansi Sharma Scuba diving is definitely the most interesting water sports of all time. It gives us the opportunity to explore the underwater species which we cannot see from outside. Ever wondered how do all those species we usually find on Discovery channel look like? Or how does it feel to really touch them or have a real look at them outside of the TV sets? This is what Scuba Diving offers; it gives you once in a lifetime experience which…

structures such as sea shells and coral skeletons decreases. Consequently, insufficient carbonate ions present in the ocean can make building and maintaining shells and other calcium carbonate structures more difficult. Other than that, lower pH of the ocean menaces the marine life such as corals, mollusks, and crustaceans as they face a great challenge when their calcium carbonate shells or skeletons dissolve in the acidic ocean. According to Rodolfo-Metalpa et al. (2011), corals, mollusks and…

33-km long island of Aruba is sited on the Caribbean Sea at the south. It combines three other nations to form the Kingdom of Netherlands. Inhabitants here have a Dutch citizen and there is a moderate population at the island. You do not need to sail all the way to Africa to look at ostriches any longer, because Aruba is home to 80 of these intriguing birds!

Comb Jellies are a type of jellyfish that have eight “comb rows” of cilia that are fused together and arranged along their sides. In Figure 1, the fused cilia can be seen easily along the length of the red lines. The cilia are used to propel the animal through the water. Some of them move through the water by doing a flapping motion with their lobes or undulations of the body. They usually have two tentacles, but lack stinging cells. To capture their prey by using sticky cells, called…

Hairy Chested Yeti Crab The hairy chested yeti crab and sometimes known as the Hoff crab after David Hasselhoff, Kiwa tyleri, (Bittel) belong to a group called squat crabs are extraordinary creatures for different reasons. Some including their outer appearance and the way they live in the climates where most other crabs or lobsters couldn’t survive. The white hair body and the spikes on its legs have been due to it adapting to its habitat and climate. (Palermo) Its living conditions are very…

Crabs are a type of crustacean that occur within mangrove ecosystems and can be found from high tide through to low tide levels. Crabs shelter underneath logs and in cool places to avoid drying out and many create burrows for refuge from larger prey, it can also be the site of mating and incubation. Other crabs use burrows to store their food as the water tide rises or lowers. Red fingered marsh crabs and fiddler crabs are commonly active at low tides where they are often out looking for food,…

Trophic Cascade: Effect of Hemigraspus sanguineus on Intertidal Food Chain Abstract Hemigraspus sanguineus (Asian crabs), an invasive species, are found in multitude on east coast and more precisely along the long island sound. The end goal of this experiment is to see what long term effect of having this invasive crab could have on other organisms in the tides, more specifically littorina littorea (periwinkle snails). This would be achieved by studying the interaction between Asian crabs,…
