Behavioral and Chemical Ecology of Marine Organisms with Respect to Tetrodotoxin
نویسنده
چکیده
The behavioral and chemical ecology of marine organisms that possess tetrodotoxin (TTX) has not been comprehensively reviewed in one work to date. The evidence for TTX as an antipredator defense, as venom, as a sex pheromone, and as an attractant for TTX-sequestering organisms is discussed. Little is known about the adaptive value of TTX in microbial producers; thus, I focus on what is known about metazoans that are purported to accumulate TTX through diet or symbioses. Much of what has been proposed is inferred based on the anatomical distribution of TTX. Direct empirical tests of these hypotheses are absent in most cases.

The Chemical and Evolutionary Ecology of Tetrodotoxin (TTX) Toxicity in Terrestrial Vertebrates
Tetrodotoxin (TTX) is widely distributed in marine taxa, however in terrestrial taxa it is limited to a single class of vertebrates (Amphibia). Tetrodotoxin present in the skin and eggs of TTX-bearing amphibians primarily serves as an antipredator defense and these taxa have provided excellent models for the study of the evolution and chemical ecology of TTX toxicity. The origin of TTX present ...

Echinoderm diseases have attracted little interest in contrast to the other commercial marine organisms. This study reports the pathogenesis pattern of juvenile Holothuria scabra. 11 pure bacteria were isolated from lesions of juvenile H. scabra with the symptoms of skin ulceration disease. Phylogenetic identification based on 16S rRNA gene sequences analysis revealed that they belonged to the ...

For more than 50 years, organic chemists have been interested in the novel chemical structures and biological activities of marine natural products, which are organic compounds that can be used for chemical defense and chemical communication by diverse marine organisms. Chemical ecology, the study of the natural ecological functions of these compounds, is an interdisciplinary field involving ch...
متن کاملIntegrative Approaches to the Study of Baleen Whale Diving Behavior, Feeding Performance, and Foraging Ecology
For many marine organisms, especially large whales that cannot be studied in laboratory settings, our ability to obtain basic behavioral and physio logical data is limited, because these organisms occupy offshore habitats and spend a majority of their time underwater. A class of multisensor, suctioncupattached archival tags has revolutionized the study of large baleen whales, particularly wi...
