A lesson here is that “natural mechanics” support the ultimate survivalists in the marine environment of tidal zones: bio-luminescence, autonomy (dropping a tail or a leg a predator holds), and scent instead of sight (sex in the dark!).
This short article is a “thought-post”. Do these marine creatures surviving best in tidal pools offer any insights in how a mother, or a family, or a loner might survive …. as daily “tides” rise and then recede? Can a marine ecosystem inspire the ultimate survivalist in man? Think about it and please comment:
Like all ecosystems, the marine environment is full of amazing animals that can do fascinating things.
Animals throughout the global ocean must face a variety of challenges – like predators, extreme conditions and altering habitats – and have learned to overcome these adversities by adapting cool features that help them survive.
I am going to share a handful of the coolest adaptations that can be seen in critters in the Northwest Pacific.
Autonomy is an adaptation that is seen both in the marine ecosystem and on land. Animals that can automatize parts of their bodies, essentially “drop” a tail, leg or claw that a predator is holding, allowing them time to try and escape.
Searching around in tide pools you may have seen crabs very much alive, but with one or more missing legs. Most likely, that crab was being attacked and decided to automatize, rather than become a seagull snack.
Although it does take a fair bit of their energy to grow the limb back, these species can replace their limbs over time.
Another interesting adaptation that can take on many forms is scent.
One of my favorite marine animals is the nudibranch, or sea slug, known as the hooded nudibranch. This delicate, unworldly looking creature has a very cool feature – it smells like watermelon! If you were to find a hooded nudibranch and smell it or the water around it, it gives off ….
