What are all the bumps on humpback whales?
In fact, you have probably seen the hairs on humpback whales and not known what they were. The bumps on the rostrum, or head, and the pectoral fins of a humpback whale are, in fact, hair follicles. Called “tubercles,” these fist-sized bumps contain one hair follicle each, connected to a set of sensitive nerves.
Why do humpback whales have tubercles?
The tubercles allow the very large whales to execute tight turns underwater and swim efficiently; a task imperative for the humpback whales feeding. The tubercles on the flippers help to maintain lift, preventing stall, and decreasing the drag coefficient during turning maneuvers.
Why do humpback whales have barnacles on them?
Why do barnacles sit on whales? Barnacles find the bellies and backs of whales an ideal breeding ground. By hitching a free ride on whales, barnacles get a relatively safe place to live, enough water passing by them to engage in filter-feeding as a whale swims, and a proper ground to expand their colonies.
What are the white bumps on whales?
Those patchy white spots you see on gray whales are barnacles. Grays carry heavy loads of these freeloaders. The barnacles are just along for the ride. They don't harm the whales or feed on the whales, like true parasites do.
How do whales benefit from barnacles?
In the case of barnacles and whales, only the barnacles benefit from attaching to the whales, but at no biological cost to the whale. This type of symbiotic relationship is known as commensalism. In this case, attaching to the whales gives the barnacles a stable place to live, a free ride, and access to plenty of food.
Why do whales have ridges?
These grooves expand and contract, allowing the whale to scoop up giant mouthfuls of food and water when it's feeding. During feeding, the whale's mouth is open a lot so it won't get hypothermia in the cold waters. Arteries and veins in the tongue act as heat exchangers to help conserve body heat.
Why do humpback whales have ridges?
A Humpback whale can have anywhere between 14-35 of these pleats along its neck. The grooves have an important function, to help increase the volume of the mouth area and therefore the amount of potential food these creatures can get in one gulp.
Can humans get barnacles?
Animal Planet – You Don't Want a Barnacle Growing In Your Hand | Facebook | By Animal Planet | Yes, barnacles can grow in human flesh.
Do whales get anything from barnacles?
In the case of barnacles and whales, only the barnacles benefit from attaching to the whales, but at no biological cost to the whale. This type of symbiotic relationship is known as commensalism. In this case, attaching to the whales gives the barnacles a stable place to live, a free ride, and access to plenty of food.
Why do Orcas not get barnacles?
In the case of barnacles and whales, only the barnacles benefit from attaching to the whales, but at no biological cost to the whale. This type of symbiotic relationship is known as commensalism. In this case, attaching to the whales gives the barnacles a stable place to live, a free ride, and access to plenty of food.
Why do whales have pleats?
Blue Whale (Suborder: Mysticeti) The blue whale, like the humpback, has ventral pleats—creases that run vertically down the underside of a whale's jaw all the way to its stomach. When feeding, the ventral pleats expand like an accordion to accommodate ahuge amount of food-rich water.
Why do whales have blowholes?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
What are 5 facts about humpback whales?
Fun Facts About Humpback Whales
- Humpback whales grow up to 60 feet (18.3 m) long and 80,000 pounds (36.3 metric tons).
- Humpback whales can live for 80 to 90 years.
- Humpback whales have some of the longest migrations of any mammal with some populations swimming 5,000 miles (8,047 km) between breeding and feeding grounds.
What happens if you touch barnacles?
Depending on the species of barnacle, you can become infected if contact with a barnacle breaks your skin. If this happens, you should immediately clean and disinfect the wound with clean water that you did not get from the ocean. If there is any debris in the wound, you need to scrub it clean.
How do I remove barnacles from my skin?
Liquid nitrogen therapy, or cryogenic treatment, may be used to treat barnacles of aging and freeze them off. Some common forms of treatment for barnacles of aging include: Low-potency Glucocorticoid Creams: The creams can be applied on the person's skin once or twice each day.
Can barnacles grow inside humans?
Yes, barnacles can grow in human flesh.
Do dolphins get barnacles?
The highly specialized coronulid barnacle, Xenobalanus globicipitis, attaches exclusively to cetaceans, particularly dolphins from tropical and temperate waters, but little is known about the factors that drive the attachment location on its hosts.
What are throat pleats?
The throat pleats extend from the mouth to the navel and allow the mouth to expand to a large volume for more efficient capture of the small animals they feed on. These "pleated throat grooves" distinguish balaenopterids from other whales.
Why do whales have a spout?
Both baleen and toothed whales breathe through blowholes–the whale's version of nostrils. The telltale spouts that are formed on the surface occur when whales expel warm air that meets colder air on the surface and condenses into small water droplets.
What comes out of a whales spout?
If you ever watch a whale breathe, you'll see plumes of mist shoot out of a hole in its head. Contrary to popular belief, that's not seawater. It's actually a cocktail mix of hot air and bacteria.
Has a humpback whale ever killed a human?
It's rare, but it has happened. Unlike recreational sailors, whale-watch captains are actively pursuing large marine mammals. They are required by law to keep 100 yards between the ship and the whale, but there are occasional accidents. In Hawaii, for example, whale-watching boats strike a few whales per year.
Is it safe to swim with humpback whales?
Is swimming with whales dangerous? If you are respectful to the whales and follow directions it is quite safe. Humpback whales are some of the most gentle and considerate animals in the world, despite their size.
What’s inside a barnacle?
Barnacles secrete hard calcium plates that completely encase them. A white cone made up of six calcium plates forms a circle around the crustacean. Four more plates form a "door" that the barnacle can open or close, depending on the tide. When the tide goes out, the barnacle closes up shop to conserve moisture.
How do humans get barnacles?
The cause of barnacles of aging is genetic; the tendency to develop them is inherited. The spots start as slightly raised and light brown spots, gradually thickening until they present a rough and wart-like appearance. Barnacles of aging slowly darken and can turn black.

Do sharks get barnacles?
Sharks don't have algae or barnacle problems despite being underwater all their lives. Shark skin is made up of tiny rectangular scales topped with even smaller spines or bristles.
Why do whales have lines on their belly?
These are tubercles. Each one of these tubercles is about the size of your fist and encases one or two hairs called vibrissae. It is thought that these hairs are most likely used to help the whale feel different vibrations in the water column.
Can a whale actually swallow a human?
Despite occasional reports of whales scooping people into their mouths, it's incredibly rare—and for all but one species, swallowing a human is physically impossible. On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed” by a humpback whale off Cape Cod, Massachusetts.
Has anyone been swallowed by a whale?
James Bartley (1870–1909) is the central figure in a late nineteenth-century story according to which he was swallowed whole by a sperm whale. He was found still living days later in the stomach of the whale, which was dead from harpooning.
