Jewel Beetles, Escaped Cobra, and Hungry Gators, Oh My!

We discussed many different forms of adaptive mechanisms of different animals in class yesterday.  I scoured the internet for some others, but found these guys to be especially awesome:

Male Anglerfish: the clingy boyfriend who moves in, lives on your couch and doesn’t have any intention of getting a job

Video

Recently, we’re spoken extensively about sexual dimorphism and the difference between males and females.  Often times, the males and females vary in appearance based on the amount of energy they invest in raising young.

The anglerfish, a member of the Lophiiform order, displays an extreme example of sexual dimorphism.  The males, a fraction of the size of females, lack the the luring apparatus used to attract prey.  They have a highly developed sense of smell, however, used to detect the pheromones given off by females.  Once a female has been found, the male bites her body and an enzyme fuses his jaw to her flesh.  He gains nutrients from her bloodstream and in effect, becomes the ultimate freeloader.  Often times, multiple males are found attached to females since anglerfish are hard to come by.

The curiously strong, not so jumbo shrimp

The Pistol Shrimp, a species of Alpheus, is capable of making cavitation bubbles by snapping its one (or sometimes two) over-sized claws.  In the process of making the bubbles, a jet of water is shot out of the socket of the claw at speeds up to 62mph and can emit a deafening “crack” that reaches up to 218 decibels (louder than a get engine).  The bubble blast can also reach a temperature of up to 5000 degrees Celsius to stun small fish and other shrimp.  I would hate to be caught in this guy’s line of fire…
