Advances in Invertebrate Biohybrid Robotics: Leveraging Nature for Locomotion and Sensing in Engineered Systems

Advanced Intelligent Systems, EarlyView.
This review explores invertebrate biohybrid robots that integrate living organisms—such as insects, jellyfish, spiders, and sea slugs—into robotic systems for locomotion, sensing, and actuation. The advantages in efficiency and cost, discuss control, and power challenges are highlighted, and future considerations to guide the development of sustainable,

A study on structural comparisons of α-chitin extracted from marine crustacean shell waste

Carbohydrate Polymer Technologies and Applications, 2021
In the present study, chitin was extracted from marine crustacean shell waste (shrimp, crab, squilla and lobster) using traditional chemical methods (deproteinisation and demineralization) and its physicochemical and structural properties were ...

A C1qDC Protein (HcC1qDC6) with Three Tandem C1q Domains Is Involved in Immune Response of Triangle-Shell Pearl Mussel (Hyriopsis cumingii)

Frontiers in Physiology, 2017
C1q-domain-containing (C1qDC) proteins are a family of proteins with a globular C1q (gC1q) domain and participate in several immune responses. In this study, a C1qDC gene was identified from the triangle-shell pearl mussel Hyriopsis cumingii (designated ...

Stirring up the relationship between quantified environmental DNA concentrations and exoskeleton‐shedding invertebrate densities

Environmental DNA, 2021
The application of eDNA techniques for the detection, monitoring, and conservation of biodiversity holds great promise. While many studies apply eDNA techniques in aquatic systems to determine the presence or absence of a given species, using eDNA for ...

Enhanced Thermal Stability and Antibacterial Properties of Biodegradable Chitosan Composite Films Reinforced With Clove Essential Oil and Graphene Oxide

Journal of Applied Polymer Science, EarlyView.
This study developed biodegradable chitosan films reinforced with clove essential oil and graphene oxide. The films exhibit hydrophobicity, strong antibacterial properties, and improved thermal stability. The films could maintain their antibacterial efficacy after 28 days of storage.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

The Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Heat Shock Protein 40 (HSP40) in Pacific White Shrimp (Litopenaeus vannamei): Molecular Cloning, Tissue Distribution and Ontogeny, Response to Temperature, Acidity/Alkalinity and Salinity Stresses, and Potential Role in Ovarian Development

Frontiers in Physiology, 2018
Heat shock proteins (HSPs), a family of conserved proteins that are produced by cells in response to stresses, are known as molecular chaperones with a range of housekeeping and cellular protective functions.

Reproduction in deep‐sea vent shrimps is influenced by diet, with rhythms apparently unlinked to surface production

Ecology and Evolution, 2022
Variations in offspring production according to feeding strategies or food supply have been recognized in many animals from various ecosystems. Despite an unusual trophic structure based on non‐photosynthetic primary production, these relationships ...

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated
