The coelacanth Latimeria chalumnae is the only living relic of a fossil group of crossopterygian lobe-finned fish1–4. We describe observations of its locomotion in a natural environment using six individuals observed from the research submersible Geo in the Indian Ocean at a depth of between 117 and 198 m. Past speculation on the pattern of locomotion has included crawling with the paired fins on the rocky ocean bottom, stalking like a large piscivorous grouper, or even fast swimming in open… Expand
Locomotion, fin coordination and body form of the living coelacanth Latimeria chalumnae
TLDR
A primary swimming function for the primitive sarcopterygian fin is indicated and earlier evolutionary assumptions of a more open-water life style of coelacanth fishes are confirmed. Expand
Observations on locomotion and feeding of released coelacanths, Latimeria chalumnae
TLDR
Two line-caught coelacanths, Latimeria chalumnae, were released for observation of their free-swimming movements in the open sea at a depth of about 50 m, and a new nomenclature is proposed for the caudal fin region and finnage. Expand
The Coelacanth Latimeria chalumnae
TLDR
The most important distinguishing feature of these fishes is the division of the neurocranium into two parts, an anterior, ethmo-sphenoid portion and a posterior, otico-occipital portion with an intracranial joint between them. Expand
Feeding ecology and evolutionary survival of the living coelacanth Latimeria chalumnae
TLDR
The activity pattern, feeding behaviour, prey abundance and hunting success of the coelacanth is studied to evaluate possible links between environmental conditions, feeding ecology and evolutionary success of this ancient fish. Expand
Habitat and population size of the coelacanth Latimeria chalumnae at Grand Comoro
TLDR
Only the west coast of Grand Comoro is a suitable coelacanth habitat with more structural complexity and prey fish abundance than other coastlines of the island and this small relict population seems to be stable. Expand
A fiftieth anniversary reflection on the living coelacanth, Latimeria chalumnae: some new interpretations of its natural history and conservation status
TLDR
For this year's 50th anniversary of the famous discovery of the first living coelacanth, retraced the routes and visited the main actors of this zoological drama, facilitated by novel interpretation of earlier data and expeditions to the Comoro Islands. Expand
Home range and migrations of the living coelacanth Latimeria chalumnae
TLDR
Large home ranges and highly mobility in a topographically narrow habitat apparently favoured inbreeding of the small local island population. Expand
Habitat requirements of the living coelacanth Latimeria chalumnae at grande comore, Indian Ocean
the seminal receptacles were removed, fixed in Bouin, embedded in paraff in , and serial sections at 3 8/zm were prepared. The receptacles of most mult iparous females so sampled ( N > 4 0 ) wereExpand
The ecology and conservation of the coelacanth Latimeria chalumnae
SynopsisStudies on the ecology of the living coelacanth, Latimeria chalumnae, are reviewed and assessed. Early predictions on the life history of the coelacanth have proved to be accurate but recentExpand
The ecology and conservation of the coelacanth Latimeria chalumnae
TLDR
The coelacanth is a highly specialised, precocial fish which occupies a unique place in biology and international efforts should continue to be made to understand and conserve this remarkable fish. Expand

Early tetrapods converge on Stegocephalia and allied groups in early Carboniferous time and these and the Devonian fishes are the key‐material. Expand
