Nature is full of beauty and horrors in equal measure. Some animals may look perfectly sweet and harmless, but when they open their mouths, that illusion is over in an instant! Just the mere sight of their oral cavities can make you flee the scene. So out in the wild, an animal’s strongest weapon may be its mouth, which is why there are some very, very creepy ones!
The sea lamprey has an eel-like body without paired fins. Its mouth is jawless, round and sucker-like, and as wide or wider than the head; sharp teeth are arranged in many concentric circular rows. There are seven branchial or gill-like openings behind the eye. Sea lampreys are olive or brown-yellow on the dorsal and lateral part of the body, with some black marblings, with lighter coloration on the belly. Adults can reach a length of up to 120 cm (47 in) and a body weight up to 2.3 kg (5.1 lb).
The lamprey uses its suction cup-like mouth to attach itself to the skin of a fish and rasps away tissue with its sharp, probing tongue and keratinized teeth. A fluid produced in the lamprey’s mouth, called lamphredin, prevents the victim’s blood from clotting. Victims typically die from excessive blood loss or infection. After one year of hematophagous feeding, lampreys return to the river to spawn and die, a year and a half after the completion of metamorphosis.
Leatherback Sea Turtle is the largest of all living turtles. they also known as lute turtle or leathery turtle. They can be found in all tropical and subtropical oceans, and its range extend well into the Artic Circle.
They may seem friendly, but who would have thought behind their friendly looks, they have a very creepy mouth. They have hundreds of sharp teeth that resemble thorns called papillae all the way down to their gut. Although it looks scary, their creepy mouths are very useful. It’s like a food-crusher for them.
Their favorite food is the jellyfish. So, those creepy teeth that help them not to sting by the jellyfish tentacles. and those creepy teeth help prevent the slippery body of jellyfish from coming out of their mouths when they eat it.
Sarcastic fringeheads live in the pacific waters, off the coast of North America – from San Francisco, USA to Baja California in Mexico. They are ambush predators, so they like to stake out a hide-y hole that offers them both protection and a great vantage point from where to pounce on prey.
Once they’ve reverse parked into their chosen nook, they’ll aggressively charge at anything that comes too near – including divers. And rumour has it, they don’t like to let go.
When rival males get too close to each other they unfurl shockingly large and colourful mouths and make gaping threats at one another, like yupping muppets.
If one of the males does not back down, this will escalate into a full-scale kissy battle – with the two rivals pushing mouth to mouth against each other in order to establish who’s the biggest.
The goblin shark (Mitsukurina owstoni) is one of the creepier fish out there! It has a long, prominent snout covered with special sensing organs (ampullae of Lorenzini) that help it to sense electric fields in the deep, dark water it calls home. It also has unusual coloration, ranging from pinkish to purplish grey, with bright blue around the edges of its fins. But even stranger is its jaw. Though close to the head in this picture, it can be extended to the length of its snout to help the goblin shark ambush fish, squids and crustaceans.
