CMS agrees on protection of 21 species of shark, ray and sawfish

Article shows hope for coral reefs

The BBC Earth section has posted an extended article about coral regeneration after bleaching events. Entitled ” The corals that came back from the dead”, the article talks about the “Phoenix Effect” which was first described in 1992 by David Krupp. It describes a process whereby corals can regrow from a small fragment of life after a sea temperature rise. Up until now, this has been observed only in disk corals, but the articles cites Peter Mumby’s experience with Porites sp corals in Rangiroa lagoon, French Polynesia.

Paper studies inter octopus asphyxiation

A new paper by Christine Huffard and Mike Bartick has been published in the journal Molluscan Research. Entitled “Wild Wunderpus photogenicus and Octopus cyanea employ asphyxiating ‘constricting’ in interactions with other octopuses, it catalogs several instances in which “aggressive constriction” has been seen in an instance of apparent sexual cannibalism and in an attempt to eliminate a competitor for a food source.

Study into shark social behaviour

A new study published in the Behavioural Ecology and Sociobiology journal suggests that shark social behavior is determined by an individual’s predisposition to be social or not.

Whilst this will come as no surprise to those that have experienced them in the wild, it does help to overcome the preconception that sharks are not sentient.

Western Australian shark cull halted

The BBC reports that the shark cull that was being carried out in Western Australia has been vetoed by the Environmental Protection Agency (EPA). The Western Australian state government had instituted seven drum line baited traps in an effort, it said, to prevent shark attacks on the state’s beaches. This caused a worldwide protest, and the policy has now been overturned by the EPA, citing the fact that there was “a high degree of scientific uncertainty” about its efficacy.
