Pycnogonids (sea spiders) are commonly collected at bathyal and abyssal. It's not a good time to be a coral. Less than a third of coral reefs have legal protection from fishing and other damaging human activity. And as. Typical coral mariculture tables found at Pulau Serangan. Here I briefly .

Despite the fact that most toxicological studies of cnidarians have focused on the class Anthozoa, the order Scleractinia remains relatively unexplored. Scleractinian corals, also called stony corals, are the most abundant reef-forming cnidarians found in coral reefs throughout the world [ 8 ]. In an earlier study, variable toxicity was found in several scleractinian corals from the Great Barrier Reef [ 9 ].

In the present study, the chemical composition and the biological activities of the aqueous extracts of three scleractinian corals collected in the Mexican Caribbean — Pseudodiploria strigosa, Porites astreoides, and Siderastrea siderea — were assessed for the first time.

The biological activities evaluated were toxicity to crickets, hemolysis, vasoconstriction, and nociceptive activity. Furthermore, enzymatic activities such as phospholipase A2 PLA2serine protease, and hyaluronidase activity were investigated. Methods Laboratory animals The animals were permitted free access to standard mouse food pellets and water ad libitum. Refined chemicals used for buffer preparations, deionized water, and HPLC grade water were purchased from J.

All reagents used in the determination of protein concentration and in electrophoretic analysis were obtained from Bio-Rad USA. The protein content of the aqueous extracts was determined by the Bradford assay [ 10 ], using a standard curve prepared with lyophilized bovine serum albumin. Injections were performed using a 0. After the injection, the crickets were placed in small plastic containers with food and water ad libitum.

Hemolysis assay In order to determine the presence of cytolysins in the extracts, the hemolytic activity in human and rat erythrocytes was monitored according to a previously reported method [ 12 ].

Different concentrations of the aqueous extracts 0. The A of the supernatant containing the hemoglobin released from lysed erythrocytes was measured in a spectrophotometer.

Isolated rat aortic ring assay The assay was carried out in order to determine whether or not the extracts contain components that produce effects on the cardiovascular system [ 13 ]. After a final adjustment of the passive resting tension to 1. Once a stable contractile tone was reached, the bathing medium was renewed to restore a resting tension of 1.

The bathing medium was changed again to restore the original resting tension, and then the aqueous extracts were added to the organ bath.

The isometric tension was measured by a Grass FT03 force-displacement transducer connected to a Grass 7D polygraph. The responses were expressed as a percentage of the initial contraction achieved with phenylephrine. Formalin test Acute neurogenic and chronic inflammatory nociception of the extracts were measured using the rat paw formalin test [ 14 ].

Results We show that clownfishes morphological characters are linked with ecological niches associated with the sea anemones. This pattern is consistent with the ecological speciation hypothesis.

Furthermore, the clownfishes show an increase in the rate of species diversification as well as rate of morphological evolution compared to their closest relatives without anemone mutualistic associations.

Conclusions The effect of mutualism on species diversification has only been studied in a limited number of groups. We present a case of adaptive radiation where mutualistic interaction is the likely key innovation, providing new insights into the mechanisms involved in the buildup of biodiversity. Due to a lack of barriers to dispersal, ecological speciation is rare in marine environments.

Hoegh-Guldburg had already concluded coral lacked the evolutionary ability to adapt and survive in the Anthropocene.

Instead he suggests that the best hope for the future of reefs would come from political action rather than scientific innovation. When coming from a pillar in the field, the assessment that politicians are better suited than his peers to preserve the future of coral comes across quite cynically bleak.

But the fact that the term super coral was first used in the media by a distinguished scientist from a skeptical, pejorative perspective only serves to highlight the biases the scientific establishment has long held against coral restoration concepts and ideas. I believe this conservative attitude displayed by many of the eldest coral researchers in the field has actually impeded development of progressive concepts that will help preserve global coral biodiversity and reef health.

A classic Coral Morphologic image: Back then, the majority of coral researchers were focused on studying dead and dying corals in the wild, rather than figuring how to keep them alive and reproducing. Inafter a fruitless search for a mentor in either coral aquaculture or corallimorph taxonomy, I took a leap of faith to develop Coral Morphologic as an independent platform for science, art, education, aquaculture, and public communication.

Empathy, or the lack thereof, is usually the difference between a person caring about an issue or not. While charismatic megafauna like pandas have long been the literal face of the environmental movement, corals lack a face entirely.

Without a brain, cuddly fur, or eyes to make contact with, it is easy to see why they have been misunderstood for so long. But what they lack in cute facial features, corals make up through their captivating fluorescence, geometric beauty, and remarkably futuristic life history strategies.

Rather than focusing on the habitat-scale declines of the reef, Coral Morphologic instead chose to highlight the individual-scale of the coral animals in a way that builds empathy and symbiosis between human and coral.

This focus on the individual was precisely our modus operandi in presenting the pioneering Acropora prolifera living along PortMiami as a super coral; one that defies expectations and serves as an inspiring example of surviving against all odds. A perfect example is in the water alongside the highway connecting Miami to Miami Beach. A look from shore reveals the rocky riprap shoreline littered with trash and plastics of all kinds.

The water is murky green and visibility can be less than a meter at low tide. Not ten meters away from this shore, endless traffic belches out acidifying CO2 and the fumes of fossil fuel on a daily basis. Multiple times throughout the year, the county issues E. The discovery of these highway-living corals followed shortly after finding the hybrid Acropora prolifera in Basically, my thought process was: Alongside them live a myriad of soft corals, sea fans, sponges, and other invertebrate reef species.

After introducing the seawall-living Acropora prolifera to the world as a super coral during the TEDx talk, Coral Morphologic made the conscious decision to use the term urban coral over the scientifically-ambiguous super coral.
