Though sometimes called the Mexican walking fish, the axolotl (Ambystoma mexicanum) is not a fish at all, but an aquatic salamander that remains in its larval form throughout its life. Because axolotls can regenerate most of their body parts, including entire limbs and portions of the brain and spine, they’re popular subjects in scientific-research labs.
These wonderfully strange creatures only seem alien to us because they are so different from us. Nothing showcases the biodiversity of our planet better than a look at species we find bizarre or unusual. All of these critters have found totally different niches in nature than we have. Sadly, species are being lost rapidly every single year, and the biodiversity of our planet is shrinking as a result of our human influence. If we want amazing species like the sea pig and the spider crab to continue to thrive, we need to work actively to preserve and protect the natural environment.
The goblin shark is, without a doubt, one of the weird ocean animals that looks more like the predators from the thriller shark movies. This living fossil sports a protruding nose or stout to detect its prey. Along with its unique and extendable jaw that appears to unhinge when feeding, the overall appearance of the goblin shark is both fascinating and terrifying at the same time.
When they hatch, they quickly infect other local anemonefishes. Parasites, by definition, don’t aspire to kill their host. After all, if the host dies, the parasite loses its home and food source. However, in the case of the tongue-eating louse, some individuals can grow to be so large that the hapless anemonefish struggles to close its mouth. Eventually, as you might imagine, this hinders the host’s ability to eat.
The daintily named sea pig is actually a kind of locally abundant sea cucumber that inhabits the world’s abyssal plains up to 3.7 miles beneath the surface. It gets its name from a characteristic pink, eggplant-shaped body and bloated legs that give it a porcine appearance. Like their shallower cucumber cousins, sea pigs play an important role in marine ecosystems. They feed on detritus that falls to the seafloor from the rich waters above, whether plankton or a whale carcass. They walk along on a few large tube feet, using a combination of muscle contractions and body fluids. Modified pairs of legs can act as antennae to detect food.
