Portuguese Man o' War: An Organism Made of Organisms?

The video explores the Portuguese man o' war, a siphonophore that resembles a jellyfish but is not one. Siphonophores are unique organisms that challenge scientific classification, as they are composed of specialized zooids that function both independently and as part of a whole. These zooids include nectophores for movement, gastrozooids for feeding, and gonophores for reproduction. Despite their collaborative nature, each zooid can act independently, making siphonophores a complex subject of study. The video concludes with a caution against touching these creatures due to their sting.

In what way do the zooids of a siphonophore function differently from those in colonial organisms like corals?

What challenges do biologists face when studying siphonophores?
