They are a little bit of a mystery to us humans, especially in their younger stages of life. However, what we do know is that their feeding habits involve catching prey such as small invertebrates with small lures that reside above their noses.
This lure catches the prey and the coffinfish eat them straight away. It is called the illicium and is a feature that is common with anglerfish. This illicium can be lowered back into a groove on their face.
This is needed when considering the risks they are subject to from natural and manmade sources. They are sometimes, cruelly, sourced for alternative medicine by humans, as well as being endangered by pollution.
They grow to around 8 or 9 inches, making them a little bigger than their seahorse relatives. However, some scientists have even reported them growing up to 13 inches or more!
They are very independent creatures from the moment they are born and are usually ready to breed at around two years old. They feed on a diet of plankton, fish in their larval stage, amphipods, and small shrimp.
They do this by sucking them up through their snout. Unlike their seahorse relatives, they can not curl their tails around seaweed, kelp, and seagrass to stay safe during a storm. For this reason, they are often found washed up on the shores if the weather has been particularly bad.
