Sharks, paddlefishes and several other aquatic vertebrates
have similar sensory systems have a sixth sense, and can detect weak electrical fields in the water and use this information to detect prey, communicate and orient themselves.
Some aquatic vertebrates
, for example, have the ability to see a wide spectrum of colors, varying between ultraviolet and red (Yokoyama, 2008).
Globally, nearly 22% of all evaluated aquatic vertebrates
are on the endangered list--this includes fish and amphibians.
The question remains as to what aquatic vertebrates
produced the coprolites and cololites.
Terrestrial and aquatic vertebrates

Like the recreational sport in which fishermen enjoy the lure of catching fin-tailed aquatic vertebrates
, the fraudulent practice of phishing is also out to lure--but in this case the targets are unsuspecting victims asked to divulge personal information.
Approximately 460 million years ago, the anterior gill arches of some aquatic vertebrates
evolved into jaws and their supporting structures, including the hyomandibular bone.
IT must be the dreaming spires that send Oxford to sleep at the Kassam Stadium, but the boys from boffin alley are an entirely different kettle of cold-blooded aquatic vertebrates

They can occur in very large numbers and serve as food for fish, water birds, and other aquatic vertebrates
Specifically, the precise functional design in the feeding modes of terrestrial relative to aquatic vertebrates
reduces opportunism in prey capture, leading to competition for specific prey sizes and character displacement (cf.
Overview of USEPA Tests with Aquatic Vertebrates

Summary: TEHRAN (FNA)- People experience the world through five senses but sharks, paddlefishes and certain other aquatic vertebrates
have a sixth sense: They can detect weak electrical fields in the water and use this information to detect prey, communicate and orient themselves.
Despite the known action of perchlorate on iodide uptake by the mammalian thyroid gland (Capen 1997; Wolff 1998) and evidence of perchlorate occurrence in aquatic ecosystems, remarkably few studies have investigated the effects of perchlorate on thyroid function of aquatic vertebrates
However, aquatic vertebrates
with rudimentary legs disappear from the fossil record about 360 million years ago, says Jennifer A.
Estrogenic endocrine-disrupting chemicals abnormally stimulate vitellogenin gene expression and production in the liver of many male aquatic vertebrates
