What type of symbiotic relationship do barnacles and whales have?
commensalism MORE ON THIS: The relationship between these barnacles and humpback whales is an example of commensalism, where one species benefits and the other is unaffected. The barnacle benefits from this relationship because it is provided with a place to live and filter food.
What do barnacles do to whales?
They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.
How are barnacles and whales commensalism?
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.
Do barnacles protect whales?
On some whales, too many barnacles can cause drag. Minor skin irritations or infections may arise. On the plus side, the barnacles can actually protect the whales, like a suit of armor.
Why do whales have barnacles?
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 is the symbiotic relationship between barnacles and crabs?
This Sand Crab is infected with a parasitic barnacle. The leathery sac protruding from beneath the crab's abdomen is the egg-producing body of the barnacle living inside the crab. Hormones secreted by the barnacle cause male crabs to become females, and once the infection takes hold the crabs are unable to reproduce.
Should barnacles be removed from whales?

Why do whales get barnacles?
Barnacles are opportunistic filter feeders which means they try and grab as much nutrients as they can that floats past them with their hair 'arms'.

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.
Do barnacles have brains?
Abstract. The central nervous system of the cypris larva of Balanus amphitrite consists of a brain and posterior ganglion.
Do whales like barnacles?
The barnacle-whale relationship is generally considered to be obligate commensalism — a type of symbiosis where one species benefits, and the other isn't affected either way.
Can a barnacle grow in a human?
Animal Planet – You Don't Want a Barnacle Growing In Your Hand | Facebook | By Animal Planet | Yes, barnacles can grow in human flesh.
Do barnacles feel pain?
Pain is in the Brain. Crustaceans have long been viewed as maintaining reflexes that do not cause internal suffering, which would mean they do not truly feel pain (as noted by Elwood 2019). A reflex involves the firing of relatively few neurons resulting in a very fast response to stimuli.
Do lobsters feel pain when boiled alive?
U.K. researchers say crabs, lobsters and octopuses have feelings — including pain. The nervous systems of these invertebrates are at the center of a bill working its way through Britain's Parliament.

What animal is immortal?
jellyfish Turritopsis dohrnii 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.
Is it cruel to cook lobster live?
Most scientists and animal activists agree that it is cruel to boil a live lobster. Lobsters do not have an advanced nervous system, but they do understand how to stay away from anything that may hurt them. Placing them in boiling water will cause them to feel pain until the second they die.

Maisie Tomlinson, from the campaign group Crustacean Compassion, which organised the letter, told BBC News: "It's really not acceptable to be boiling animals alive, to be cutting them up alive.
