Comparison of MA silks from Araneus diadematus and Nephila clavipes shows variation in fibroin sequence and properties between spider species provides the opportunity to investigate the design of these remarkable biomaterials.
Strategies for life in flow: tenacity, morphometry, and probability of dislodgment of two Mytilus species
The attachment strength of sessile intertidal organisms is continuously challenged by the hydrodynamic forces generated by breaking waves and the attachment strength, or tenacity, can vary for one of the dominant competitors for space.

It is probable that elastic proteins will provide a wealth of chemical structures and elastic mechanisms that can be exploited in novel structural materials through biotechnology.
Silk Properties Determined by Gland-Specific Expression of a Spider Fibroin Gene Family
A gene family from the spider Araneus diadematus was found to encode silk-forming proteins (fibroins) with different proportions of amorphous glycine-rich domains and crystal domains built from poly(alanine) and poly(glycine-alanine), which allows for a range of mechanical properties according to the crystal-forming potential of the constituent fibroins.
The structure and properties of spider silk
Functional design of horse hoof keratin: the modulation of mechanical properties through hydration effects.
The results lead to the hypothesis that the density of secondary bonding sites within the hoof-wall keratin matrix proteins provides the hoop organ with the means to modulate tissue properties, even though this epidermal tissue functions after the cells have died.
Elastin as a random‐network elastomer: A mechanical and optical analysis of single elastin fibers
The physical properties of single, 5–8‐μm diameter, water‐swollen elastin fibers have been investigated on a microtest apparatus attached to a polarizing microscope. Analysis of the mechanical and…
The role of elastic energy storage mechanisms in swimming: an analysis of mantle elasticity in escape jetting in the squid, Loligo opalescens
The role of elastic energy storage in jet locomotion of the squid, Loligo opalescens, is considered and analysis indicates that these muscles are used at virtually 100% of their potential through the jet cycle.
Recombinant human elastin polypeptides self‐assemble into biomaterials with elastin‐like properties
Here, using recombinant polypeptides based on sequences in human elastin, it is demonstrated that as few as three hydrophobic domains flanking two crosslinking domains are sufficient to support a self‐assembly process that aligns lysines for zero‐length crossl linking, resulting in formation of the crosslinks of native elast in Tropoelastin.
