Southeast Asian snakes of the pareatidae family — the oriental slug-eating snakes — specialize in eating slugs and snails, and because the majority of snails are dextral with the shells on the right side, the snakes attack from the left, grabbing the shell with its upper jaw and sticking its lower jaw into the gap. The snakes have also evolved asymmetrical mouth parts with more fangs on one side than the other to help them eat the dextral snails. These changes, however, make it difficult for them to eat sinistral snails, especially as the snakes continue to attack from the left.”

Remains of a crusader fortress built from October 1178 until March 1179. The cost of cutting the stones was 80,000 golden dinars, it is said that Saladin himself offered 100,000 dinars if the crusaders do not build it. The castle was maintained by the Templers, the masters of Safad on the east, and was built at a strategic point at the passage of the Jordan river. The crusaders never saw it finished. In the spring the fight between the crusaders and Saladin renewed, following a raid by the Crusaders on Muslim shepherds near Banias further north. On 25/08/1179 the army of Saladin appeared in front of the fort. Other forces were sent to the Galilee to set havoc. On 30 of August, five days after the beginning of the siege, an underground tunnel that was dug was big enough. Wood was placed and set on fire in the tunnel, and the roof collapsed with the tower of the fortress on top. Some 1000 people were in the fortress, most were slaghtered on the spot and some on their way to Damascus. Saladin stayed to eversee the destruction work carried out and finished.
Note the break in the wall: it was caused by an earthquake. The fortress is located on a local sinistral strike-slip fault - as all of the Syrian African rift. Indeed, the eastern half of the fortress moved north relative to the western one by more than 2 metres.

A Câmara Municipal do Funchal assinala presentemente mais uma edição da Semana Europeia da Mobilidade na cidade do Funchal, com uma série de iniciativas que visam promover uma maior sensibilização de todos os cidadãos para uma utilização mais eficiente dos meios de transporte disponíveis.
A Semana Europeia da Mobilidade é uma iniciativa anual da Comissão Europeia, que se iniciou em 2002, e que e que tem vindo a ganhar dinamismo. Em 2013, por exemplo, 1.931 cidades europeias aderiram a esta iniciativa, o que revela o impacto positivo que este evento tem vindo a ter ao longo dos últimos anos.
"As nossas ruas, a nossa escolha", é o tema central deste ano de 2014, tendo em vista os problemas urbanos decorrentes do excessivo uso do automóvel, que contribuem para a diminuição da qualidade de vida, ou seja pelos problemas causados pela elevada concentração de poluentes tóxicos emitidos ou pelo elevado sedentarismo causado pela dependência do transporte particular, a que se alia ainda a sinistralidade rodoviária.
O programa da Semana da Mobilidade Funchal 2014, apresenta um programa diversificado de atividades, desde uma exposição denominada de “Autocarros na Madeira 100 Anos de História”, que estará disponível ao público até 22 de Setembro, na Praça do Município; conferências, passeio de bicicleta, prova de orientação, desfile de moda, entre outras atividades.

O Conselho Municipal de Quelimane através da Vereação de Actividades Económicas da Autarquia, procedeu na manha desta quinta-feira a entrega de um novo espaço para a venda de calçados. Com a iniciativa segundo explicou o responsável do pelouro, Celestino Ginote, pretende-se colocar fim a proliferação de vendedores ambulantes de sapatos nas ruas e avenidas da Cidade e emprestar um ambiente afável e livre transito para os munícipes.
O Espaço em referência localiza-se nas proximidades do mercado Chabeco. São no seu todo mais de vinte e nove vendedores ambulantes, que beneficiaram de espaços para construção das suas bancas, para exercer as suas actividades de venda de sapatos de forma segura “ este mercado traz mais uma valia aos munícipes da urbe, que terão facilidades de compra de sapatos e outro tipo de calçado num único local”- refere Celestino Ginote.
Refira-se que este é o segundo mercado, entregue aos vendedores ambulantes em menos de um mês, as autoridades municipais, efectuaram a entrega em Dezembro ultimo o de venda de roupas usadas, sempre com o intuito de oferecer melhores condições de transitabilidade nas ruas e avenidas bem como reduzir os níveis de sinistralidade a que estes comerciantes estavam votados exercendo as suas actividades na via pública.
Pareas chinensis
CHINESE SLUG SNAKE
INTERESTING FACT:
Since most snails are dextral (their shells spiral to the right),
snakes of the Pareidae family, i.e. oriental slug snakes, attack from the left. In order to facilitate such a hunting strategy, almost all of them have much more teeth on the right mandible (lower jaw) than on the left.
"Snail shells can spiral to the left (sinistral) or to the right (dextral), as determined by a single gene, and a study has found the advantage of being in the minority sinistral group: they survive predation by snakes much better than dextral snails. The effect of this advantage is so great they could separate into a distinct species.
(...)
Southeast Asian snakes of the pareatidae family — the oriental slug-eating snakes — specialize in eating slugs and snails, and because the majority of snails are dextral with the shells on the right side, the snakes attack from the left, grabbing the shell with its upper jaw and sticking its lower jaw into the gap. The snakes have also evolved asymmetrical mouth parts with more fangs on one side than the other to help them eat the dextral snails. These changes, however, make it difficult for them to eat sinistral snails, especially as the snakes continue to attack from the left.”

Pāpala kēpau or Umbrella catchbird tree
Nyctaginaceae (Four O'Clock family)
Indigenous to the Hawaiian Islands
Hawaiʻi Island (Cultivated)
The early Hawaiians used an adhesive gum from pāpala kēpau for repairing bowls.
The milky sap from pāpala kēpau was used for cuts. The cooked leaves were used to cure pāʻaoʻao (childhood disease with physical weakening) and for lepo paʻa (constipation).
Pāpala kēpau are truly fascinating plants with a sad, but interesting, cultural history. A sinistral use for the sticky fruit was to trap native birds. [6] The captured victims provided feathers for the strikingly colorful cloaks (capes), helmets, lei, images and kāhili. Birds such as 'ō'ō and mamo were plucked of their few moulting yellow feathers and set free to grow more for the next season. However, this was not the case with the 'i'iwi and 'apapane which were covered with red- or green-colored feathers and would not have survived the plucking. They were captured, plucked and eaten.
For all you lefties out there, the lightning whelk is the only whelk that has a left (sinistral) whorl and opening unlike most univalves. Some cultures believe this left-oriented characteristic gives the lightning whelk special powers in addition to its great beauty.

This ancient Norman style doorway on the east side of the castle in Dalton reveals much. Judging by the heavy wear on the step in the foreground this may have been the main passage of entry for those who were required to appear before the magistrates.
There is evidence of an iron slot in the centre of the step so there must have been some sort of gateway where most people were required to enter the castle and of course, judging by the wear, they entered on the left, the sinistral side, considered evil by our forebears. Were they judged before they were tried? An interesting conundrum.
The arch is of course original but the wooden door must be a recent replacement. I would be interested to know whether the steps are original.
Usually, the shell has no visible umbilicus by the aperture, but there is an umbilicus-like slit (1) in the apex caused by the change from the sinistral larval shell (protoconch) to a dextral shell.
Shell height 3.5 mm. Salting on tidal River Dee, Flintshire, Wales. December 2018.

A member of the family Achatinellidae and the endemic Hawaiian subfamily Achatinellinae, is known only from the island of Maui. All members of this species have sinistral (left-coiling), oblong, spindle-shaped shells of five to seven whorls that are coarsely sculptured. Newcomb’s tree snail reaches an adult length of approximately 0.8 in (21 mm) and its shell is mottled in shades of brown that blend with the bark of its native host plant, Metrosideros polymorpha or the ohia tree.
