Cephalopod Ink: Production, Chemistry, Functions and Applications

Marine Drugs, 2014
One of the most distinctive and defining features of coleoid cephalopods—squid, cuttlefish and octopus—is their inking behavior. Their ink, which is blackened by melanin, but also contains other constituents, has been used by humans in various ways for ...

Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

Conservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.

Effects of Body Size and Environmental Region on the Nutritional Value of Small Pelagic Species in the California Current

Fisheries Oceanography, EarlyView.
ABSTRACT We evaluated the effects of regional environment and body size on the nutritional traits of five small pelagic species differing in habitat use, feeding behavior, and importance as prey for top predators in the California Current Large Marine Ecosystem (CCLME).

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

The Tentacular Strike Behavior in Squid: Functional Interdependency of Morphology and Predatory Behaviors During Ontogeny

Frontiers in Physiology, 2019
This study examines the relationship between morphology and predatory behaviors to evaluate the ontogeny of the specialized tentacular strike (TS) in Doryteuthis opalescens squid reared under laboratory conditions [hatching to 80 day-old; 2–16 mm mantle ...

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

Insect Molecular Biology, EarlyView.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Cephalopod Tissue Regeneration: Consolidating Over a Century of Knowledge

Frontiers in Physiology, 2018
Regeneration, a process consisting in regrowth of damaged structures and their functional recovery, is widespread in several phyla of the animal kingdom from lower invertebrates to mammals.
