Bizarre New Deep-Sea Creature Found in Antarctica December 2nd, 2008 More than 700 new species, such as this baby crustacean Ceratoserolis above, were discovered in the depths of the waters around Antarctica. The findings mean deep-sea conditions can support a diverse array of species, a surprise to researchers.
parasitic louse (crustacean family) that attacks fish. Enters fish through gills, then attaches itself to base of tongue. Louse restricts blood flow to tongue, feeding off it, causing the tongue to wither and die where it then takes its place. Then it lives in the fishes mouth, working as a fully functioning tongue and living off its blood and saliva. Apparently this does not harm the fish and is the only known case of a parasite replacing a whole organ.
Watch out though, Longhorned Cowfish can be a dangerous pet. If cornered it is able to secrete a deadly toxin right through their skin! This poison will normally only effect the other members of the tank, but be very careful and never handle this fish! You can check out the Longhorned Cowfish in an aquarium in the videos below.
