Did you know that the deadly, highly venomous blue-ring octopus cannot tell the sex of another blue-ring at first sight? They have to feel the other one first in order to be able to figure it out. An encounter can be witnessed in this video where two blue-ring octopuses (Hapalochlaena sp.) meet each other for the first time. Love at first sight or disaster date? Watch to find out!
Frogfishes are a member of the anglerfish family and eat pretty much everything, shrimps, fish and even other frogfish. The strike itself is accomplished with the sudden opening of the jaws, which enlarges the size of the mouth up to 12 times, pulling the prey into the mouth along with water. The water flows out through the gills, while the prey is swallowed and the food pipe closed with a special muscle to keep the victim from escaping. In addition to expanding their mouths, frogfish can also expand their stomachs to swallow animals up to twice their size.
