Sensory Organ facts

While investigating facts about Sensory Organs and Sensory Organization Test, I found out little known, but curios details like:

A Narwhals tusk is actually it's left tooth which breaks through its lip. It is soft, and covered with small holes that fill with water and basically make the tusk a sensory organ, like a nose or ears.

how sensory organs work?

Although there is no specialized sensory organ for time, our perception of time nevertheless depends on the rate of change in different sensory modalities. In the absence of sensory input, e.g. under anaesthesia, the sense of time is often lost or impaired.

What sensory organs do sharks have quizlet?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what sensory organs did the shark have. Here are 23 of the best facts about Sensory Organs Definition and Sensory Organs Function I managed to collect.

what sensory organs do sharks have?

1. Saw shark has a pair of barbels in the middle of the snout. They are used as a sensory organ which facilitates detection of the prey.

2. Just like sharks, piranhas are equipped with special sensory organs which help them detect blood in the water.

3. Grasshoppers have a pair of antennas on the head. They serve as sensory organ which detects various stimuli from the environment.

4. Angel shark has a pair of barbels on the snout. Angel shark uses these sensory organs to detect the prey and taste the food.

5. Cod has three dorsal fins, two anal fins and one pair of pectoral fins. It has beard-like barbel on the chin, which facilitates finding of food (it acts like sensory organ).

6. Web-spinners have thin and linear antennas divided in 15 to 32 segments, depending on the species. Antennas are used as sensory organ.

7. Ticks can detect their hosts via body odor, temperature, moisture and vibration. Sensory organ which helps in identification of potential hosts is located on the legs.

8. Russian desman has eyes, but they are not functional (animal is blind). Instead of eyes, Russian desman obtains sensory information from its environment via Eimer's organs (touch-sensitive organ located on the snout).

9. Unlike other species of pythons, woma python does not have heat-sensing pits (type of sensory organs located close to the mouth, used for detection of warm-blooded animals).

10. Silver arowana has elongated body, wedge-shaped head and wide mouth that opens in drawbridge-like manner. Two barbels on the lower jaw serve as sensory organs (they facilitate detection of food). Jaw bones, palate, tongue and pharynx are covered with teeth.

Why are sensory organs more prominent in cephalopods?

You can easily fact check why do animals need sensory organs by examining the linked well-known sources.

Wrinkled pinkish skin of naked mole rats is covered with around 100 hairs on the head and tail. These hairs function as sensory organ which facilitates orientation in the dark underground environment.

A Narwhal's tusk is actually a canine tooth that protrudes through the lip, on the left side of the upper jaw. It is a sensory organ used to collect information from the environment around them, and not in-fact used for spearing fish or jousting. - source

Hermit crab has two long ocular stalks with eyes on the top and antennas which serve as sensory organs.

Kangaroo rat has big head, large eyes and small ears. Their whiskers act as sensory organ which detects vibration of the ground.

Entire body of catfish is covered with taste buds that can detect chemicals in the water and respond to touch. Greatest concentration of sensory organs is located on the whiskers, also known as barbels. Catfish develops up to 4 pairs of whiskers.

When the eyes are open what sensory organs?

Camel spider has elongated jaws (called chelicerae), 4 pair of long legs and one pair of leg-like sensory organs (called pedipalps) near the jaw.

How many sensory organs?

Woodlouse has one pair of antennas on top of the head. They function as sensory organs which facilitate navigation in the space. Uropods are small, tube-like structures on the rear end of the body. They release foul-smelling substance when woodlouse is faced with danger.

Bowhead whales have a 12-foot long penis-shaped organ in their mouth that is filled with nerves and is made of the same tissue as a penis is. Scientists believe that this bizarre organ is used to regulate body temperature and/or as a sensory organ.

Octopuses' pupils will always be oriented horizontally due to special sensory organs called statocysts.

Sharks have a sensory organ that enables them to detect electrical fields in the water

Saliency detection is considered to be a key attentional mechanism that facilitates learning and survival by enabling organisms to focus their limited perceptual and cognitive resources on the most pertinent subset of the available sensory data
