By Hermann Ehrlich

This is the second one monograph by means of the writer on organic fabrics of marine starting place. The preliminary publication is devoted to the organic fabrics of marine invertebrates. This paintings is a resource of contemporary wisdom on biomineralization, biomimetics and fabrics technology with admire to marine vertebrates. For the 1st time in clinical literature the writer offers the main coherent research of the character, starting place and evolution of biocomposites and biopolymers remoted from and saw within the vast number of marine vertebrate organisms (fish, reptilian, birds and mammals) and inside of their special hierarchically prepared structural formations. there's a wealth of latest and newly synthesized info, together with dozens of formerly unpublished pictures of targeted marine creatures together with extinct, extant and dwelling taxa and their biocomposite-based constructions from nano- to micro – and macroscale. This monograph studies the main correct advances within the marine organic fabrics study box, mentioning numerous methods being brought and explored through detailed sleek laboratories.

It was shown that the external skin surfaces of marine Laticauda snakes studied by Lillywhite and coworkers are hydrophobic. Thus, the skin can interact with a microfilm of air at the surface of the stratum corneum. Probably, “variation in the nature of this air film is correlated with species differences in the efflux of water when these snakes are aquatic” (Lillywhite et al. 2009). Sea snakes are known to shed their skin with relative frequency. Probably due to hydration damage of corresponding layers of their skin, which seems inevitable over time (Tu et al.

2011a, b). However, sea snake bite is the cause of human fatalities as well. These animals are known to produce venom that contains neurotoxins (Carey and Wright 1960), some of them (erabutoxins) are similar to curare. These toxins can block the nicotinic acetylcholine receptors on the post synaptic membranes (Tamiya and Yagi 2011). Westhoff and co-workers (2005) described them as “predators that hunt during the day, at dawn or at night. e. that may be useful for the detection of water motions produced by prey fish.
