interesting facts about shiripm anatomy: A shrimps heart is in its head.
Here's a fun shrimp fact: shrimp hearts are located in their heads! Looks like shrimp don't have to choose when it comes to going with their head or their heart! But what is the reason for this crustacean's curious body composition?
Earthworms are one of the most common animals with multiple hearts. These decomposers can be found pretty much everywhere, as long as there's dirt for them to live in.
To many, leeches are horrifying creatures. To a few, they're impressive and miraculous. They have 32 brains, 2 hearts, 300 teeth grouped in 3 jaws, five pairs of eyes...
The fruit fly, long the organism of choice for scientists studying genetics and basic biological processes, still harbors some secrets of its own. One of these is the fly's so-called “head-heart.” This tiny pumping station supplies hemolymph—the insect equivalent of blood—to the fly's antennae.
Such an enormous pressure would require a very large, strong and slow-beating heart. But, they postulate, instead of a single large heart, the Barosaurus probably had some eight hearts.
In the hagfish, the systemic heart pumps blood through the gills, and by way of arteries through the rest of the body. The accessory hearts are all located on the venous side of the circulation to pump blood back to the systemic heart.
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Snails have more teeth than any animal.
A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
Explanation: Black milk is the slimmest milk containing very little amount of fat (0.2%) is produced by Black rhinoceros.
Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
Spiders usually have eight eyes but few have good eyesight.
Some spiders have median eyes that can detect polarised light and they use this ability to navigate while hunting.
Ants, like other insects, have a heart that pumps hemolymph rhythmically.
Their heart lies above the stomach on the upper surface of the animal (but still below the carapace of course!) A lobster's circulatory system is known as an “open” system whereas our system is known as a closed system. The heart of an adult lobster beats 50-136 beats per minute.
The circulatory system of adult blue crabs, Callinectes sapidus, was mapped by either injecting barium sulfate into intact animals followed by radiography or by resin corrosion casts (Batsons Monomer). Seven arteries arise from the heart.
Do prawns have brains? Answer: Yes, they do, but their brains are not very big. Prawns and shrimp do have a centralized collection of nerve cells that can be considered to be a brain.
Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus' blood appear blue.
Based on the discovery of a single tooth, researchers say they have identified an ancient species of giant platypus.

Other animals naturally have no tongues, such as sea stars, sea urchins and other echinoderms, as well as crustaceans, says Chris Mah via email.
But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
Animals that don't need sleep (bullfrogs and dolphins) Animals that don't need rebound sleep after using up all their energy (bees) Animals that show harmful side effects from sleep deprivation (humans)
It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
How Many Hearts Do We Have? You surely know that humans and giraffes have just one heart, as most animals do—but not all.
It is an octopus. Yes, the multi-tentacled creature that has always intrigued us has three hearts and nine hearts. Read on to know why. The two hearts of this creature are made for the gills and are used to pump blood.
This three-eyed animal is called a tuatara. The third eye of a tuatara, located on the top of its head, has all of the right parts: a lens, a retina, and nerves leading to the brain.
