Day 23 prompt Ancient
The Horseshoe Crab is actually not a crab at all, but is more closely related to spiders and scorpions. This ANCIENT creature has existed for more than 400 million years - that's older than dinosaurs! They breed only during full moons, new moons, and high tides in May and June! Unlike mammals and birds, they use hemocyanin to carry oxygen through their blood, a copper-based compound that makes their blood blue. There are four species of Horseshoe Crab still surviving today, and they're under threat from overfishing (used for bait and fertiliser) and to a lesser extent from the science industry as a synthetic option has been found that performs an identical function. Nevetheless, the IUCN Red List classifies the American Horseshoe Crab as Vulnerable, and the Tri-Spine Horseshoe Crab as Endangered. The other two species are still listed as Data Deficient.
Brazilian street artist Sipros is well known for his portraiture of exaggerated characters mainly painted on city walls as colorful murals. One of his best pieces is in Murray Hill on 35th Street and 2nd Avenue, featuring surrealist Salvador Dalí with his iconic mustache and an extra large set of ears. #graffiti#muralartist
