Caudal fin absent; tail beyond anal fin slender and usually cylindrical; no dorsal any, mouth small or large filament e. The weak pulses are implicated in the electrosensory system see Chapter 11, this volume ; the strong pulses have offensive or defensive value. The Electric Eel. One Along the coast of South America the too small for both, and the adult has to rest needs to have one in the hand to be able to Peruvian diving petrels feed on anchovies in a nearby hole. The enhanced rate of sequence evolution of this gene likely underlies the species-level variations in the electric signal.

The distribution of several of them is so peculiar as to suggest that their arrival has been fortuitous and not dependent on dry-land connections.

Clothbound Excerpt The brief history of this species is now well known. Nor is it only rafts from rivers that need be considered. Fugu genome analysis provides evidence for a whole-genome duplication early during the evolution of ray-finned fishes. FEBS Letters93—6. Many years ago Cuvier and Valenciennes described a Fundulus from Puerto Rico, but it has remained known from the single type specimen in Paris, since the other type specimens were shown to be a Gambusia.
San Diego: Academic Press, pp. The importance of fresh-water fishes to students of geographical distribution depends primarily on two facts. At rest the resistance of innervated and uninnervated faces is relatively high. The bridge builders are those zoogeographers who are prone to postulate vast continental connections, which they believe existed in what is now the deep sea, in order to provide bridges over which the land faunas could march to destinations to which they obviously got somehow.
As discussed in respect to electrocytes of Astroscopus this finding indicates that the resistance of the uninnervated face is very low.

The caudal, innervated surface on the left has some small processes from it. A Fundulus has been described from them by Fowler from the old van Rijgersma collection, but the specimens are only doubtfully distinct from a common North American brackish water killyfish Fundulus hereroclitus.

The oviparous cyprinodonts of the family Cyprinodontidae likewise occur from central North America to Argentina, but it has recently been shown Myers, that the dominant South American genera are closely related to African rather than to North American forms. Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype.
We know that many living things could not be found where they are if the land and sea had always been exactly as they exist today, and only a study of paleogeography, or the geography of ancient times, will enable us to understand how plants and animals moved about over the face of the earth and reached the places where we now find their living descendants.
My chief contention is that the proponents of Holarctic dispersal have given too little attention to contrary conclusions in other groups and have, perhaps, ridden along on the coattails of the mammal evidence a little more easily than the evidence of their own groups actually warrants.
Each cell is contained in a connective tissue chamber, and successive layers of cells in the anterior posterior direction are fairly accurately aligned, one behind the other. California Acad.With David Greenfield he co-authored the book Fishes of the Continental Waters of Belize ().
Inthe doradid catfish Rhinodoras thomersoni of Venezuela and Colombia was named in his honor. Dr. Thomerson introduced the senior author (Donald C.
Taphorn) to the study of fishes and led Taphorn’s first trip to South America. Although the nonfiction book should be full of definite facts, the author can add some emotions to make this memoir or chronic and not so bored. It is a perfect literature for studying.
