Ebook "Biology and conservation of horseshoe crabs" is organized, as the title implies, into two main sections: biology and conservation. The biology section is divided into two subsections: (1) populations and habitats and (2) physiology, reproduction, and development. The conservation section is divided into three subsections: (1) commercial use and management of populations and habitat, (2) culture and captive breeding, and (3) public awareness and community-based conservation.

Ebook "Changing global perspectives on horseshoe crab biology, conservation and management" reports significant progress of scientific research on horseshoe crabs, including aspects of evolution, genetics, ecology, population dynamics, general biology and physiology, within the recent 10 years. It also highlights the emerging issues related to world-wide conservation threats, status and needs. The contributions in this book represent part of an ongoing global effort to increase data and concept sharing to support basic research and advance conservation for horseshoe crabs.

Liquid chromatography-mass spectrometry (LC-MS/MS) was used for measurement of the variation of tetrodotoxin (TTX) in a horseshoe crab Carcinoscorpius rotundicauda collected from Can Gio coast, Ho Chi Minh City, Vietnam from May 2021 to May 2022 over the seasons, body weight and gender.

Horseshoe crabs are ancient marine arthropods with a long evolutionary history extending back approximately 450 million years, which may benefit from their innate immune systems. However, the genetic mechanisms underlying their abilities of distinguishing and defending against invading microbes are still unclear.

Arthropod cuticles play an important role as the first barrier against inva-ding pathogens. We extensively determined the sequences of horseshoe crab cuticular proteins. Proteins extracted from a part of the ventral side of the cuticle were purified by chitin-affinity chromatography, and separated by two-dimensional SDS⁄PAGE. Proteins appearing on the gel were designa-ted high molecular mass chitin-binding proteins, and these proteins were then grouped into classes based on their approximate isoelectric points and predominant amino acid compositions. ...

In the horseshoe crab, bacterial lipopolysaccharide (LPS) induces exocyto-sis by granular hemocytes, resulting in the secretion of various defense molecules, such as lectins and antimicrobial peptides, via a G protein-mediating signaling pathway. This response is a key component of the horseshoe crab innate immune response against infectious microorganisms. Here, we report an endogenous amplification mechanism for LPS-induced hemocytes exocytosis.

Endotoxin-neutralizingprotein (ENP) of the horseshoe crab isoneof themost potent neutralizersof endotoxins [bacterial lipopolysaccharide (LPS)]. Here, we report on the inter-action of LPS with recombinant ENP using a variety of physical and biological techniques. In biological assays (Limulusamebocyte lysate and tumour necrosis factor-a induction in human mononuclear cells), ENP causes a strong reduction of the immunostimulatory ability of LPS in a dose-dependent manner.
