These extremes take multiple forms. This note reports an abnormal weather event in which winds, apparently Force 10 on the Beaufort Scale (90-100 km/hour), killed hundreds of birds at a farmhouse in the Karoo, South Africa. The wind was so strong that it removed birds from their roosts in trees and flung them against the walls of the farmhouse with such force that it killed them. There are no published accounts of comparable events in southern Africa.","PeriodicalId":155392,"journal":{"name":"Biodiversity Observations","volume":"49 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139172888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The snails were amphibious; they moved about in damp sediment when the sea had receded and readily left the water in the laboratory to move on dry surfaces. The siphon, normally used for the intake of oxygenated water in submerged snails, remained open when snails were out of water, suggesting that they can also breathe air. Videos of snails taken from below explained  the mechanics of their stop-and-go locomotion. Close-up photographs also revealed the presence of a pallial eye at the top of the  siphonal canal. When a snail was partially buried in soft sediment, its pallial eye remained above the sediment. The pallial eye may orient the snail and help it detect potential dangers when its tentacular eyes are obstructed.","PeriodicalId":155392,"journal":{"name":"Biodiversity Observations","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133329501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
