Abstract Large‐scale digitization projects such as #ScanAllFishes and oVert are generating high‐resolution microCT scans of vertebrates by the thousands. Data from these shared with community using aggregate 3D specimen repositories like MorphoSource through various open licenses. We anticipate an explosion quantitative research in organismal biology convergence available data methodologies to analyse them. Though available, road a series images analysis is fraught challenges for most...
A broad diversity of biological organisms and systems interact with soil in ways that facilitate their growth survival. These interactions are made possible by strategies enable to accomplish functions can be analogous those required geotechnical engineering systems. Examples include anchorage soft weak ground, penetration into hard stiff subsurface materials movement loose sand. Since the have been ‘vetted’ process natural selection, they governed same physical laws both engineered...
The northern clingfish, Gobiesox maeandricus, is able to adhere slippery, fouled and irregular surfaces in the marine intertidal environment. We have found that fish can equally well with a broad range of surface roughness, from finest sandpaper (R(a) = 15 µm) textures suitable for removing finish flooring 269 µm). fishes outperform man-made suction cups, which only smoothest surfaces. adhesive forces clingfish correspond pressures 0.2-0.5 atm below ambient are 80-230 times body weight fish....
A new genus and two species of miniature clingfishes are described based on specimens collected from dense stands macroalgae in intertidal shallow subtidal areas along the coast southern Australia. The genus, Barryichthys , is distinguished other genera Gobiesocidae by unique features adhesive disc, including elongate papillae disc regions B, reduction and/or loss several elements cephalic lateral line canals, lower gill arch skeleton, neurocranium, having distinct types pectoral-fin rays....
Nettorhamphos radula, new genus and species, is described from two specimens, 20.3–40.2 mm SL, trawled sponge algae reefs between 30–40 meters in depth offshore Fremantle, Western Australia. The taxon distinguished all other members of the Gobiesocidae by having vast fields tiny conical teeth throughout oral jaws that are arranged multiple, regular rows along lingual surface premaxilla dentary. tentatively considered a close relative southern Australian endemic clingfish taxa (Posidonichthys...
We contrast 2D vs. 3D landmark-based geometric morphometrics in the fish subfamily Oligocottinae by using landmarks from CT-generated models and comparing morphospace of to one based on images. The shape variables capture common patterns across taxa, such that pairwise Procrustes distances among taxa correspond trends captured principal component analysis are similar xy plane. use two sets test several ecomorphological hypotheses literature. Both data reject hypothesis head correlates...
ABSTRACT The stingray family Myliobatidae contains five durophagous (hard prey specialist) genera and two planktivorous genera. A suite of morphological features makes it possible for the hard specialists to crush mollusks crustaceans in their cartilaginous jaws. These include: 1) flat, pavement-like tooth plates set an elastic dental ligament; 2) multiple layers calcified cartilage on surface jaws; 3) struts running through 4) a lever system that amplifies force jaw adductors. Examination...
Abstract The skeleton of the “wings” skates and rays consists a series radially oriented cartilaginous fin emanating from modified pectoral girdle. Each ray small, laterally skeletal elements, radials, traditionally represented as simple cylindrical building blocks. High‐resolution radiography reveals pattern calcification in batoid wing their organization within ray, to be considerably more complex phylogenetically variable than previously thought. Calcification patterns radials varied...
SUMMARY Mantis shrimp (Stomatopoda) generate extremely rapid and forceful predatory strikes through a suite of structural modifications their raptorial appendages. Here we examine the key morphological kinematic components strike that amplify power output underlying muscle contractions. Morphological analyses joint mechanics are integrated with CT scans mineralization patterns toward goal understanding mechanical basis linkage dynamics performance. We test whether four-bar mechanism...
Abstract The notorious jaws of the white shark Carcharodon carcharias are widely feared, yet poorly understood. Neither its bite force, nor how such force might be delivered using relatively elastic cartilaginous jaws, have been quantified or described. We digitally reconstructed a to estimate maximum and examine relationships among their three‐dimensional geometry, material properties function. predict that in large sharks may exceed c . 1.8 tonnes, highest known for any living species,...
Northern clingfish use a ventral suction disc to stick rough substrates in the intertidal zone. Bacteria, algae and invertebrates grow on these surfaces (fouling) change surface properties of primary substrate, therefore attachment conditions for benthic organisms. In this study, we investigate influence fouling roughness adhesive strength northern clingfish, Gobiesox maeandricus. We measured tenacity unfouled fouled over four roughnesses. exposed 6 weeks Pacific Ocean, until they were...
Three lineages of cartilaginous fishes have independently evolved filter feeding (Lamniformes: Megachasma and Cetorhinus, Orectolobiformes: Rhincodon, Mobulidae: Manta Mobula); the structure branchial filters is different in each group. The Rhincodon typus has been described; species within Lamniformes simple filamentous filters, but anatomy ultrastructure mobulid rays varies functional interest. In most fishes, gill rakers are elongated structures located along anterior ceratobranchial...
We report a strategy for preserving the structural features of collagen triple helix in turbostratic graphite.
While artificial suction cups only attach well to smooth surfaces, the Northern clingfish can surfaces ranging from nanoscale rough stone. This ability is highly desirable for technical applications. The morphology of fish's disc and its slimy have been described before, here we aim close gaps in biomechanical understanding, transfer principles cups. We demonstrate that margin critical feature enabling attachment surfaces. Second, friction measurements show rim increased on substrates...

. –The evolution of biological materials is a critical, yet poorly understood, component in the generation biodiversity. For example, diversification spiders correlated with evolutionary changes way they use silk, and material properties these fibers, such as strength, toughness, extensibility, stiffness, have profound effects on ecological function. Here, we examine dragline silk across phylogenetically diverse sample species Araneomorphae (true spiders). The silks studied are generally...
Elasmobranchs, particularly sharks, function at speed and size extremes, exerting large forces on their cartilaginous skeletons while swimming. This casts doubt the generalization that are mechanically inferior to bony skeletons, a proposition has never been experimentally verified. We tested mineralized vertebral centra from seven species of elasmobranch fishes: six sharks one axially undulating electric ray. Species were chosen represent variety morphologies, inferred swimming speeds...
The batoid fishes (electric rays, sawfishes, skates, guitarfishes, and stingrays) are a trophically morphologically diverse clade in which the observed range of diets is product feeding mechanism with few parts therefore limited number functional interactions. This system allows an intriguing comparison to complex network associations apparatus bony anatomically simple framework for investigations mechanisms underlying evolution phenotypic diversity. We quantified morphology from...
The majority of the skeleton elasmobranch fishes (sharks, rays and relatives) is tessellated: uncalcified cartilage overlain by a superficial rind abutting, mineralized, hexagonal blocks called tesserae. We employed diversity imaging techniques on an ontogenetic series jaw samples to investigate development tessellated in stingray (Urobatis halleri). compared these data with cellular changes that characterize calcification bony skeletons. Skeletal growth characterized appearance tesserae as...
