The mechanics of locomotion in the squid Loligo pealei: locomotory function and unsteady hydrodynamics of the jet and intramantle pressure.
High-speed, high-resolution digital video recordings of swimming squid (Loligo pealei) were acquired. These recordings were used to determine very accurate swimming kinematics, body deformations andExpand

The structure and properties of spider silk
Abstract Silks from the spider's orb-web are amongst the very best structural materials produced by nature: spiders can produce a large aerial filter from a minimal amount of material. By studyingExpand

The locomotory function of the fins in the squid Loligo pealei
Kinematic data of high spatial and temporal resolution, acquired from image sequences of adult long-finned squid, Loligo pealei, during steady swimming in a flume, were used to examine the role ofExpand

Patterns Of Circular And Radial Mantle Muscle Activity in Respiration and Jetting of the Squid Loligo Opalescens
1. 1. By simultaneously recording the electromyographic (EMG) activity of squid mantle muscles, changes in mantle cavity pressure and changes in mantle diameter, we have been able to distinguish theExpand

Tuned oscillations in the swimming scallop Pecten maximus
Scallops swim by rythmic opening and closing of the valves. Water ejected from the mantle cavity during closing of the valves generates thrust that propels the animal. The closing phase is powered byExpand

The structure and physical properties of invertebrate and primitive vertebrate arteries.
Light and electron microscopy and in vitro inflation experiments were conducted on the aortae of three different invertebrate species: the lobster Homarus americanus, the horseshoe crab LimulusExpand

Mechanics of Jet Propulsion in the Hydromedusan Jellyfish, Polyorchis Pexicillatus: I. Mechanical Properties of the Locomotor Structure
A non-destructive test was developed to measure the static mechanical properties of the locomotor structure (bell) in the hydromedusan jellyfish, Polyorchis penicillatus (Eschscholtz, 1829). AExpand

Scallop Shells Exhibit Optimization of Riblet Dimensions for Drag Reduction.
Drag reduction by streamwise surface grooves, or riblets, has been observed by engineers and has been suggested to apply to certain biological systems. Drag reductions as high as 8% have beenExpand

Microfibrils provide non‐linear elastic behaviour in the abdominal artery of the lobster Homarus americanus.
1. Microfibrils are becoming increasingly recognized as an important component of the extra‐cellular matrix. However, almost nothing is known about their mechanical role in the diversity of tissuesExpand
