In the article‚ “Sunken Steel Cages Could Save Coral Reefs”‚ Gaia Vince discusses that sunken steel cages may help restore endangered coral reefs. First‚ Vince explains how the steel cages are showing results for the endangered reefs. Carbon dioxide is above the level that it needs to be‚ and that is part of why coral reefs are going extinct. The metal cages do not fix that problem‚ but they appear to show results. The steel cages are connected to a long electrical cable that triggers a chemical

Snails‚ clams‚ squids‚ chiton. Is it possible that they may all be related in some way? Could they come from the same family tree? How does an octopus related to an oyster other than living in water? Yes it is very true that all of the above named specimen evolved from the same ancestor. The hypothetical ancestral mollusk has evolved into so many different species that are adapted to live in a variety of environments. Among the many species clams and snail‚ land snails in particular‚ have evolved

Sea anemones are members of the Phylum Cnidarian. The cnidarians include the anemones‚ jellyfish‚ coral‚ Portuguese man-of-war and hydroids. Their characteristics include a soft body with two tissue layers arranged around a central gut cavity. A ring of tentacles surrounds a central mouth‚ and the tentacles endure stinging cells which contain nematocysts used to capture food and for defense. ("Marine Life Profile: Sea Anemones”) The two basic body forms among the cnidarians are the polyp‚ which looks

Porifera? Porifera is a phylum under the kingdom of Animalia. Porifera is the oldest phylum in this kingdom and has been around for the last 600 million years. The most common organism in this phylum is sponges. Porifera comes from the Latin words porus (pore) and ferre (bear)‚ meaning "pore-bearer". This is a reference to the numerous holes (pores) on the sponge ’s surface. Characteristics of Porifera All organisms belonging to the phylum Porifera; Have no definite symmetry Have

This sponge is in the Kingdom of Animalia‚ Phylum of Porifera‚ Class of Demosphongiae‚ Order of Verongida‚ Family of Aplysinidae‚ Genus of Aplysina‚ and Species of A. archeri. This sponge gets its name from its cylindrical shape and long tube like structure. It can grow up

Hexacorallia The subclass Hexacorallia includes 6 orders: Actiniaria (true sea anemones)‚ Antipatharia (black corals)‚ Ceriantharia (tube anemones)‚ Corallimorpharia‚ Scleractinia (true or "stony" corals)‚ and Zoanthidea. Hexacorallia includes roughly 4‚300 known extant species. As the name suggests‚ most hexacorallians have hexamerous symmetry (i.e.‚ parts in multiples of 6). The most familiar group of corals‚ the reef builders‚ includes around 650 extant species (i.e.‚ around half the known stony

NEWLY DISCOVERED DEEP-SEA MARINE CARNIVOROUS SPONGE Phylum Porifera is considered as a simplest form of animal consisting of sponges. Many families under this phylum have distinctive characteristics specifically feeding processes that help them become successful in terms of adaptation and survival despite of being simple and some are smaller compared to other marine organisms. A new species of carnivorous sponge (Phylum Porifera) have been discovered in the coast of Namibia particularly in the

The Orangespotted Sunfish (Lepomis humilis) is often confused with other sunfishes. This species is classified in the class Actinopterygii‚ order Perciformes‚ and family Centrarchidae. One characteristic that makes them stand out from other fishes are their black and orange spots. Also‚ their operculum is lined with a solid white band. Nine to ten bars can be identified on this fish. The bars on the female have a light center‚ which is a way of gender identification when the males are outside of

Climate Change Impacts on the Ocean Climate change has widespread effects. It doesn’t just affect weather and temperature. It will also have lasting effects on the ocean and the ecosystems within it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching‚ a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg‚Donner‚pg. 9‚ par 3). This bleaching can stress the reefs
