Octopus has the ability to see with its skin

In a recent study, researchers found that octopus skin contains the same light-sensitive proteins found in eyes. The skin responds to light independently of the central nervous system, and detects changes or increases in light brightness.

Rescuers have been able to rescue eight brown pelicans, but an intensive clean-up process awaits them. Pelicans must acclimate to their new surroundings for 48 hours and are afterwards extensively cleaned. They are then taken care of for two weeks after which they can return to the wild.

Currently, three of the five rhino species are critically endangered primarily due to poaching for their horns. A California biotech start-up, however has posed an unorthodox solution; creating synthetic rhino horns to offer consumers an ethical alternative. Conservationists are skeptical that synthetic horns will reduce demand for the real thing.

In 2010, Mozambique was home to approximately 20,000 elephants, but today it houses only 10,300. Almost all of the poaching occurred in the remote northern region of the country. Celso Correia, Mozambique’s new Minister of Land, Environment and Rural Development, has stated that tackling poaching is a top priority of the government.

In a recent report, Greenpeace officials noted that vaquitas are being caught and drowned in illegal gillnets, which are meant to catch totoabas, another endangered species. The vaquita population was 200 in 2012, but now only 97 individuals remain.

Researchers believe that the decline in the number of glacous winged gulls reflects changes in the availability of marine food. Considering that gulls are the ultimate diet generalist, their decline suggests some profound changes to local marine ecosystems.

European beavers pair up for life and never cheat

Less than 5 percent of animals are believed to pair together for life, yet not without instances of cheating. One of the exceptions appears to be the Eurasian beaver who is completely faithful to its partner for its entire life.  Conversely, the American beaver is known to mate with others besides their partner.

Peacocks make ‘infrasound’ noises with their tails that are about as loud as a car going by a few meters away. Researchers hypothesize that in males the sound could be used to attract females or ward away other males.

The Mexican government has approved an important measure which aims to protect the vaquita, a porpoise species thought to be the world’s rarest and most threatened marine mammal.

The vaquita is classified as Critically Endangered on the IUCN Red List

Critically Endangered

The vaquita is the smallest porpoise species in the world, reaching a maximum length of just 1.5 metres, and is the only cetacean endemic to Mexico, being found only in the upper Gulf of California.

Sadly, it also has the unfortunate distinction of being the most threatened marine mammal. Classified as Critically Endangered on the IUCN Red List of Threatened Species, the vaquita is struggling for survival as a result of becoming entangled in gill nets and trawl nets cast by commercial and artisanal fisheries to catch shrimps and fish, including sharks. It is estimated that between 39 and 84 vaquitas drown as bycatch every year, which is a worryingly high number given that, in 2007, only an estimated 150 individuals of this species remained.

Positive action

Fortunately, according to WWF-Mexico, positive action is now being taken to promote sustainable fisheries in the vaquita’s range, in measures which will benefit the species as well as fishermen and their families. A new regulation will establish shrimping standards in Mexico, and will define the types of fishing gear permitted in different zones of the country.

Drowning in fishing nets is the main threat to the vaquita

An official norm

The new regulation, known as an ‘official norm’, has come into play as a result of a WWF petition to Mexico’s President Enrique Peña Nieto. Signed by an impressive 38,000 people from 127 countries, the petition requested that measures be established to protect the vaquita whilst also ensuring that fishermen can continue to earn a living through sustainable fishing.

With this norm, drift gillnets – one of the nets used in artisanal shrimping operations in which vaquitas die incidentally – will be gradually substituted, during a three year period, for selective fishing gears that do not kill this porpoise, but that allow fishers to keep earning their livelihoods,” said Omar Vidal, WWF-Mexico’s Director General.

The effective application of the norm requires the participation and commitment of local fishermen. The optimal use of the net requires the development of particular skills; therefore, the support of the government and other organizations through training and temporary compensation programs will be essential along the fisher’s learning curve.”

This positive action represents a major opportunity to promote sustainable fisheries in the Gulf of California region, whilst simultaneously protecting an endemic threatened species.
