Picture of the week: 'Rainbow from the Sun'

This picture of a  little vividly colored wrasse was taken by Nick More.  I guess it’s the Thalasoma klunzingeri (or ruepelli), abundant over de coral reefs of the Red Sea. The suggestion of speed of the downward darting wrasse inspired  Nick to call it ‘Rainbow from the Sun’. The sun stripes behind the tail, reminiscent of the motion lines in comic strips, are created by moving the camera in the same direction as the wrasse.

 

Highlighted: Villagers against elephants in Botswana

Elephant Paradise Botswana  is now threatened by angry villagers and farmers complaining about their crops being ravaged or eaten by the elephants. Conservationists have reacted with concern to a recent decision by Botswana government to lift its ban on elephant hunting installed in 2014. Elephants are now again running the risk to be shot by any person including ivory and trophy hunters.  Botswana has the largest elephant population in Africa, with more than 135,000 roaming freely in its unfenced parks and wide-open spaces.

Highlighted: killer Orca duo eating sharks

Orca’s have the reputation of killing sharks, including the Sevengill shark in New Zealand and even the great whites in  Gansbaai South Africa. Normally Orca’s feed on the seal, which is also the favorite target for Sevengills and great whites, explaining why the Orca may occasionally attack and eat these lager shark species. Especially the large liver of the great white seems to be a  delicacy for the Orca. Port and Starboard are two old age Orca,s  thought to be responsible for the recent killing of sharks in Gansbaai, South Africa. The notorious duo has now also been spotted near Seal Island in South Africa,  a famous spot for cage diving with great whites and, with the great white visits becoming less frequent in the last years, also the Sevengill shark.

Highlighted: Vaquita on the edge of extinction

The vaquita (Phocoena sinus) about 1.50 m long, is a species of porpoise endemic to the northern part of the Gulf of California that is on the brink of extinction. The vaquita (Spanish for ‘little cow’) is the victim of bycatch from the illegal gillnet fishery. Francisco Gomez Diaz,  chairman of the museum of Whale and marine biology in Baja California Sur doubts if the species can still be saved. Investigators estimate that at present only 10-20 species might be swimming around in the Gulf of California. 

Higlighted: Tiger shark beauty award

This picture of a young female tiger shark taken by Debra Cannabal shows the beautiful markings, which normally are more conspicuous in young than in older tigers shark. But this teenage shark certainly beats all other rivals, deserving the ‘ 2019 Miss Bahamas beauty award’.

 

 

  

News: Suriname aims to reverse coastal erosion with mangroves

The  muddy coastline of Suriname has lost many of its mangroves  in recent decades. Its low-elevation coastal zones are now threatened by erosion and climate change-related sea level rise of the Atlantic. Professor Sieuwnath Naipal, a hydrologist at de Anton de Kom University at Paramaribo now attempts to reintroduce mangroves to stop such losses. Their purpose is holding coastal silt swept it by Suriname’s coastline by currents from the mighty Amazon river. The red mangrove - also called parwa - should flourish in this environment. The Amazon river mud gets caught between the parwa roots and will then hopefully expand and rise the coastline again.
