A new Reef Site in Coral Reefs (Green and Cote 2009) describes the striking densities of non-native lionfish on coral reefs in the Bahamas. Lionfish (Pterois volitans), a predator from the central and western Pacific ocean, were first sighted in 1992 off Florida and have been spreading rapidly throughout the Caribbean (USGS Nonindigenous Aquatic Species Database 2009). On deep offshore reefs off of North Carolina, they are now the second most abundant fish (Whitfield et al. 2007). Continue reading Caribbean lionfish invasion
Go check out these incredible photographs by National Geographic photographer Thomas Peschak of mantaray feeding frenzies in the Maldives. Apparently this swirling ‘cyclone‘ feeding behavior is rarely seen outside of the Maldives. Click here for a previous post on Climate Shifts for more details and video footage of Mantaray feeding behaviors. Continue reading “One-ton manta cyclonic feeding frenzy”

The megamouth shark (Megachasma pelagios) is one of the worlds rarest sharks – spotted only 43 times since its discovery back in 1976 off Oahu, Hawaii. These sharks are huge and bizzare creatures, capable of growing upwards of 5m in length, with luminescent light organs surrounding the mouth to attract plankton and small fish. So … Continue reading Endangered shark found. Eaten.
A fluff piece in more ways than one! The Institute For Figuring have been developing the ‘hyperbolic crochet coral reef’, a collective of crochet coral reef organisms knitted by hundreds of people across the globe. By altering the style of crochet through differing algorithms, the crochet reef has ‘evolved‘ an impressive diversity of reef associated … Continue reading Raising awareness of coral reefs through the art of crochet
A harbor seal, presumably from the north Atlantic, showed up in Bermuda this week and effectively debunked the global conspiracy known as AGW (Anthropogenic Global Warming). William Weaver of the group Americans for Climate Truth said in a statement “scientists have reported that thousands of species were moving away from the equator, but this sighting … Continue reading Harbor seal debunks AGW myth

First described by the naturalist Johann Julius Walbaum back in 1792, the manta ray grows in excess of 7.6m (>25ft) and weighs up to 2300kg (~5,000lbs) – about 4/5ths of … Continue reading Manta rays
