Order Xiphosura: Horseshoe Crabs

x

Horseshoe crabs are the only living creatures in class Merostomata.  The other creatures, Eurypterids, or giant water scorpions, went extinct around 200 million years ago.  Merostomates are probably the closest living relatives of the Trilobites, which have been extinct around 251 million years.

x- Giant Sea Scorpions, kinda terrifying

There are four extant (living) species of horseshoe crabs alive today: Limulus polyphemus, Carcinoscorpius rotundicauda, Tachypleus tridentatus, and Tachypleus gigas.  Limulus, which i will be focusing on in this post (because it’s the one on my exam), lives in the North American Atlantic coast, and is largely the same in external morphology since the Triassic period.

Horseshoe crabs has an unsegmented, horseshoe- shaped (hence the name) carapace (a hard dorsal, or upper, shell).  It also has a broad abdomen and a long tail-like telson, which is mostly used for digging and flipping itself back over if it gets stuck on its back.

Horseshoe crabs breathe using book gills, which are somewhat similar to the book lungs of spiders.  They have book gills under their five paired gill opercula, which are directly under the genital operculum.  The opercula move as the animal moves, and the current this creates helps to pull water through the gills. Inside are thin, vascular membranes called lamellae, and those membranes are where the gas exchange takes place.

x

Horseshoe crabs have blue blood due the use of copper- based hemocyanin to carry oxygen.  They use amebocytes to fight off infection, and their amebocytes will coagulate around as little as one part per trillion of bacterial contamination, a process that only takes 45 minutes.  This incredibly efficient system means that their blood can be used in vaccine testing, implant sterilization, and has even been taken to the International Space Station.

Telson, Turner extend partnership in Spain Juan Fernandez Gonzalez | 18-12-2013 Telson and Turner have extended their distribution agreement in Spain. The Tres60 Grupo subsidiary will produce the signals and distribute the new Turner channels – TCM HD, TNT HD and Cartoon Portugal – for the Iberian Peninsula. Telson specialises in advertising and cinema post-production, but also works with play-out services. The project with Turner required a large investment in broadcasting equipment – video servers, graphic systems and content management system – in order to integrate Telson's broadcasting centre and Turner's systems in Madrid and London. The Tres60 company is currently distributing 18 signals in Portugal and Spain. The play-out provider mostly works for international groups including NBC Universal and Viacom. The agreement with Turner has been active since 1999, when the Atlanta-based group started to operate in Spain's pay-TV market. Turner has lately been restructuring its operations in Spain, ending the pay-TV broadcasting of Cartoon Network and Cartoonito, although it has retained its online channel and has announced an on-demand service. TCM and TNT have a large presence on Spanish pay-TV platforms and are now available in high definition (HD) on most of the cable and satellite services including Canal+, Movistar TV and ONO, as well as the regional platforms R and Telecable.
