Being able to tie their body into a knot is beneficial to some moray eels and other cylindrical vertebrates for various reasons, although not all morays’ tie knots. Knot tying can generate leverage for feeding activity by moving the knot up the body, and this leverage may be affected by knot type. Three types of knots are known to have been used by morays’ and this study further elucidates this behaviour and ability. Baited Remote Underwater Videos (BRUVs) were used to compare knot tying… 
Follower fish of the goldspotted eel Myrichthys ocellatus with a review on anguilliform fish as nuclear species
The frequency and time duration of foraging associations among the goldspotted eel Myrichthys ocellatus and reef fish in a subtropical marginal reef and nuclear eel species and their followers described in the literature are investigated.
Body shape transformations by alternate anatomical adaptive peak shifts in blenniiform fishes
The results suggest that extreme elongation arose with distinct shifts in selective factors and development in the Blenniiformes, a radiation of small‐bodied substrate‐associated marine teleost fishes.
A field and video annotation guide for baited remote underwater stereo‐video surveys of demersal fish assemblages
Baited remote underwater stereo‐video systems (stereo‐BRUVs) are a popular tool to sample demersal fish assemblages and gather data on their relative abundance and body size structure in a robust,


To knot or not? Novel feeding behaviours in moray eels
It is suggested that morays have an extensive behavioural repertoire for manipulating and extracting large prey items from the interstices of the reefs where they typically hunt.
Raptorial jaws in the throat help moray eels swallow large prey
It is shown that the moray eel overcomes reduced suction capacity by launching raptorial pharyngeal jaws out of its throat and into its oral cavity, where the jaws grasp the struggling prey animal and transport it back to the throats and into the oesophagus.
Mimicry and foraging behaviour of two tropical sand‐flat octopus species off North Sulawesi, Indonesia
The key finding was that octopuses used flounder mimicry only when their movement would give away camouflage in this open habitat, which is a highly unusual circumstance of a guild of small, long-armed octopus species that shared the same habitat, den sources, food, activity period, and some behaviours.
Functional morphology of the pharyngeal jaw apparatus in moray eels
It is speculated that morays have evolved this alternative prey transport strategy as a means of overcoming gape constraints, while hunting in the confines of coral reefs.
The Moray Eels of Australia and New Zealand, with the Description of Two New Species (Anguilliformes: Muraenidae)
The types of moray eel type specimens in museums have been re-examined, their identities established, and brief descriptions of the specimens written, and a key to the 59 muraenid species of Australia and New Zealand is presented.
Elongation of the body in eels.
The diversity of axial elongation is described as well as how characters such as head length, branchial-arch length, and shape of the pectoral fins correlate with vertebral number to possibly facilitate changes in absolute diameter of the body.
Hagfish predatory behaviour and slime defence mechanism
New footage from baited video cameras that captured images of hagfishes actively preying on other fish suggest that the functional adaptations and ecological role of hragfishes, past and present, might be far more diverse than previously assumed.
A checklist of the moray eels of the world (Teleostei: Anguilliformes: Muraenidae)
A checklist of the currently recognized species of moray eels (Muraenidae) is presented and a list of nominal genera and species is given, with the current status of each.
Habitat complexity modifies the impact of piscivores on a coral reef fish population
Adult abundances in this damselfish species were strongly influenced by the densities of different predators and the availability of preferred refuges, suggesting that transient predators may be even more important than the residents.
