Canary
The Canary Islands are a province within Spain. We speak Spanish although not 'Kings Spanish' as in Madrid, but with a local dialect that can be disconcerting to visitors initially! The language seems to have more in common with S American Spanish than that spoken in the Spanish Peninsular.Alongside the official language, many people speak English and German as well.Spanish, but with a different dialect than the ones used in Spain.
Spain's principal chain islands ar two: the Balearics, off the Mediterranean coast, and the Canaries, near the Atlantic coast of Morocco/Western Sahara. Both are common holiday destinations, though the most popular by far are the Balearics - most notably Ibiza.

Non-poisonous spiders include common house spiders, daddy longlegs, and wolf spiders. These spiders do not possess venom that is harmful to humans.
The most common spiders found in Kansas include the common house spider, wolf spider, and garden spider.
