Krøyer's deep sea angler fish is a species of fish in the family Ceratiidae, the sea devils. This deep-sea anglerfish is found in all oceans, at depths of 0 to 4,400 m, but mainly between 400 and 2,000 m. Females typically are 77 cm (2.53 ft) long, but can reach 120 cm (3.9 ft). The much smaller males only reach 16 cm (0.52 ft) and they are symbiotic, as they attach themselves to a female.
Venomous fish produce strong mixtures of toxins harmful to humans which they deliver by means of a bite, sting, or stab. This results in an envenomation. As a contrast, poisonous fish also produce a strong toxin, but they do not bite, sting, or stab to deliver the toxin. Instead they are poisonous to eat because the human digestive system does not destroy the toxin they contain in their body. Venomous fish don't necessarily cause poisoning if they are eaten, since the digestive system often destroys the venom.
A blind fish is a fish without functional eyes. Most blind fish species are found in dark habitats such as the deep ocean, deep river channels and underground.

Dollfus' stargazer is a fish of the family Uranoscopidae, widespread in the Western Indian Ocean: Gulf of Suez, Gulf of Oman, and Persian Gulf. It is a marine demersal fish, and occurs at depths down to about 46 metres (151 ft). It was named in honour of Dr R. P. Dollfus who led an expedition to Egypt in 1928–1929 and who brought back some specimens of this fish which he mistakenly identified as Uranoscopus affinis. These were new to science and became the type specimens of the new species U. dollfusi, with the Gulf of Suez being the type locality.
Whitemargin stargazer is a fish of family Uranoscopidae, widespread in the Indopacific: Red Sea, Indonesia, Fiji, Samoa, and Tonga. Marine reef-associated fish, up to 45.0 cm maximal length.
Atlantic stargazer is a marine, subtropical fish of family Uranoscopidae. Its body is suited for living on the sea floor, and is one of few fish capable of bioelectrogenesis, or the ability to generate an electric charge.
Ceratias is a small genus of seadevils.
Trachicephalus uranoscopus, the star-gazing stonefish, is a species of stonefish native to the Indian Ocean and the western Pacific Ocean where it is found on muddy bottoms in estuaries.

Thalassophryne maculosa, the Cano toadfish, is a species of toadfish which is common along the Caribbean coasts of South America from Colombia to Trinidad and Venezuela. It occurs on the sandy bottoms of reef flats, lagoons, and seaward edges of reefs where it sits partially buried in the substrate. It is a venomous species with the venom being delivered through spines and wounds from the spines have been known to cause severe symptoms of pain and illness that may persist for up to a week. A study of the holotype of Batrachus uranoscopus, said to be a freshwater toadfish from Madagascar, in the Muséum national d’Histoire Naturelle in Paris found that it was most probably a misslabelled specimen of Thalassophryne maculosa and that subsequent records of Batrachus uranoscopus were attributable to Allenbatrachus meridionalis, a species found in Madagascar. T. maculosa is the type species of the genus Thalassophryne, the generic name translates from Greek as "sea toad" while the specific name is Latin for "spotted".
