Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Roadside Abundance of Anurans within a Community Correlates with Reproductive Investment
Frontiers in Ecology and Evolution, 2017 Roads and their associated effects (road-kill, pollution, etc.) have a largely negative impact on animals, especially amphibians, but not all species are affected to the same degree. Variation in life histories may explain some of these differences. Here,

Macrophages and pigment cells in the liver of tailless amphibians
Zoodiversity, 2020 The morphological features of pigment-containing cells and phagocytic cells were observed on the smears of the liver of the lake frogs. Based on an analysis of more than 1500 cells, it was concluded that cells that have pigment granules in the cytoplasm ...

Effects of guanidine on synaptic transmission in the spinal cord of the frog [PDF]
, 1977 The effects of guanidine on motoneurons of the isolated frog spinal cord were studied by adding the drug to the solution bathing the cord during intracellular recording. Guanidine (5·10–4 M) did not alter the membrane potential of motoneurons.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Characterization and mechanism of action of amphibian-derived wound-healing-promoting peptides
Frontiers in Cell and Developmental Biology, 2023 Wound-healing-promoting peptides are excellent candidates for developing wound-healing agents due to their small size and low production cost. Amphibians are one of the major sources of bioactive peptides, including wound-healing-promoting peptides.

Advanced Science, EarlyView.Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Ecology and Evolution, 2020 Many animals rely on vocal communication for mating advertisement, territorial displays, and warning calls. Advertisement calls are species‐specific, serve as a premating isolation mechanism, and reinforce species boundaries.
