Monday Archives: Fluorescent Fairy Wrasses

In the ocean, longer wavelengths of light (i.e. red) are quickly filtered out, so that with increasing depth the red pigmentation of marine life takes on increasingly inky tones. This provides excellent camouflage in the darkness and is why so many deeper-water...

Monday Archives: Bicinctus in the wild

Amphiprion bicinctus is not a common fish in the trade, but for visitors to the Red Sea, it’s a common sight. I’ve had a great fondness for clownfish since I first saw one on an old nature documentary in the 1970s, so when I first saw one in the wild I was utterly...

Miami’s Pioneering Urban Brain Coral at the Frontier of Marine Science

Symmetrical Brain Corals (Pseuododiploria strigosa) emersed during low tide along the shoreline of PortMiami. For more than a decade, Coral Morphologic has sought to shine a spotlight on Miami’s intertidal urban corals and their potential scientific value. These surprisingly resilient corals appear to avoid bleaching and stem disease better than their conspecifics offshore on the natural reefs. Over the past two years we have been working with scientists at NOAA to explain these differences using molecular lab analysis of tissue samples collected in the field. That work finally culminated in ‘Molecular Mechanisms of Coral Persistence Within Highly Urbanized Locations in the Port of Miami, Florida‘ published in the research journal Frontiers in Marine Science. We found that the Symmetrical Brain Corals (Pseuododiploria strigosa) living in the urban environment (specifically alongside MacArthur Causeway and Star Island in Miami) were predominantly colonized by the Durusdinium sp. strain of symbiotic algae (zooxanthellae) that provides the coral with photosynthetic energy during daylight hours. Durusdinium is known to be a heat-tolerant genus of zooxanthellae, and has long been investigated by scientists seeking to create bleaching-resistant ‘super corals’. However, until this study, the Symmetrical Brain Coral had rarely been observed hosting this species of zooxanthellae elsewhere in the region, making these observations here in Miami quite remarkable. Beyond the helpful symbionts, the Symmetrical Brain Corals living in the urban environment were also found to be producing proteins and enzymes known to identify and digest pathogenic invaders. These proteins could be a two-fold benefit to the coral since disease-causing microbes can be digested as food before they can infect the coral. The urban marine environments around Miami often have high concentrations of phytoplankton and turbidity in the water, along with high bacterial concentrations that frequently require ‘no swim’ public health advisories. The ability to capture and extract more energy from food could enhance its health and provide sustenance during times of bleaching. These findings from a single species of urban coral in Miami’s coastal environment suggest further investigation is warranted in the variety of other reef-building species that have self-recruited to the City’s concrete and riprap shorelines. It also demonstrates how the human-made hydrogeologic conditions around PortMiami serves as an evolutionary gauntlet selecting for corals better adapted for life in the Anthropocene.

The broodstock pairing attempts started in 2017 with one successful pair, then additional potential broodfish were obtained in 2018. Currently, there are four bonded pairs of copperband butterflyfish at IRREC. One pair (henceforth referred to as Pair A), consisting of the largest-sized individuals, is spawning consistently. Another pair has spawned a few infertile eggs but is not consistently spawning yet. Two other pairs may not be sexually mature yet. There is still a long way to go but the very large numbers of eggs laid (upwards of 50k) and fair fertilization rate (up to 35%) actually make these a viable option in the near future. http://bit.ly/newsJeremy164 Peter- A Lego Reef?? In a makeshift saltwater nursery located on an offshore Singapore island, a vital scientific experiment is taking place involving corals and sea invertebrates and Lego bricks. We needed to create flat and stable surfaces for the animals to rest on, explained Neo Mei Lin, a leading marine biologist and senior research fellow from the National University of Singapore's Tropical Marine Science Institute. Detachable Lego bricks proved very useful in helping us to hold corals and giant clams in place. http://bit.ly/newsPeter164 Remy's Bahama Llama Tip of the Week: Spring Purge Main Topic: Hawaiian Fish Ban what does it mean for us? Will this fuel a major push of captive bred options? Will we see price increases, what will be available/scarce? Will we also go over some favorites and alternative options that might float your boat.
