Box jellyfish
Although the notoriously dangerous species of box jellyfish are largely restricted to the tropical Indo-Pacific region, various species of box jellyfish can be found widely in tropical and subtropical oceans, including the Atlantic Ocean and the east Pacific Ocean, with species as far north as California ("Carybdea confusa"), the Mediterranean Sea ("Carybdea marsupialis") and Japan (such as "Chironex yamaguchii"), and as far south as South Africa (for example, "Carybdea branchi") and New Zealand (such as "Copula sivickisi").
Lighthouse lizardfish
The lighthouse lizardfish is known to live in a marine environment within a depth range of about 2–100 meters. They are native to reef-associated locations within a tropical climate. The average length of the Synodus jaculum as an unsexed male is about 10 centimeters or 3.9 inches. The maximum recorded length of the Synodus jaculum as an unsexed male is about 20 centimeters or 7.87 inches. This species is identified by its brown colored body with the dark brown splotches. This species also has transparent fins. The lighthouse lizardfish is native to the areas of Indo-Pacific, East Africa, Marquesan, Society islands, north to the Izu Islands in Japan, south to New South Wales in Australia, Palau, and Kosrae in Micronesia. This species occupies coral reefs and it is found on sand or rubble near coral heads. This species of fish is caught and sold as fresh and salted in markets. It is also common to find this species isolated, in pairs, or in small groups.
