Which mammal has 2 hearts?
Which mammal has 2 hearts, The systemic heart pumps blood around an octopus’s body, while its two branchial hearts pump blood through its two gills. Since octopus blood is very copper-rich, it’s exceptionally viscous.
What land animals have two hearts?

What animals have 2 hearts?
Some animals like the octopus have more than one heart. An octopus has one main, systemic heart that pumps blood to the whole of its body. But it also has two additional hearts, responsible for pumping blood over each of its gills.
Does a giraffe have hearts?
A giraffe heart weighs on average 11 kilograms and (like in all mammals) is composed of have two halves, the right and the left, which are each responsible for moving blood around the body. The right ventricle of the heart only has to pump blood a relatively short distance to the lungs.
Do giraffes have two brains?
The three brains of the adult male giraffes weighted respectively 722.7, 766.1 and 770.4 g, with a mean of 753.1 xb1 15.23 g (Table 1). The body weights were similar with an average weight of 703.3 xb1 50.4 kg. The EQ calculated with these means resulted in a value of 0.76 (Table 3).
Does any animal have 2 hearts?
Cuttlefish Like squids and octopuses, cuttlefish have three hearts. In addition, their hearts operate similarly to their fellow cephalopods. As you already know, the systemic heart pumps blood throughout the body, while the two branchial hearts’ sole role involves moving blood through the cuttlefish’s gills.
What animal have 2 hearts?
The systemic heart pumps blood around an octopus’s body, while its two branchial hearts pump blood through its two gills. Since octopus blood is very copper-rich, it’s exceptionally viscous.

Are there any mammals with more than one heart?
Squids have three hearts; one main heart and two branchial hearts. Octopuses and squid have three hearts. Earthworms have five hearts.
What animal has 4 hearts?
The systemic heart pumps blood around an octopus’s body, while its two branchial hearts pump blood through its two gills. Since octopus blood is very copper-rich, it’s exceptionally viscous.
Do any animals have 8 hearts?
Since octopus blood is very copper-rich, it’s exceptionally viscous. As a result, it requires a significant amount of pressure to pump blood through its body. To compensate, the octopus evolved three separate hearts to take stress off of its systematic heart and ensure it gets enough oxygen into its gills.
Do octopus has 8 hearts?
An octopus’s three hearts have slightly different roles. One heart circulates blood around the body, while the other two pump it past the gills, to pick up oxygen.
Which animal has highest number of heart?
There are three hearts beating inside octopuses and squid: one main heart that pumps oxygenated blood through the entire body and two branchial hearts that specifically pump blood through the gills to the main heart for oxygenation.
Which animal has more than 10 hearts?
Octopuses or octopi (both are technically correct) are one of the most well-known animals with multiple hearts.
