Flatworm mimicry
Fun fact! Did you know that certain flatworms are mimicked by certain types of fish?
This is speculated to be from the flatworms TTX (Tetrodotoxin) content. More research is being conducted on the topic, but mimicry like this can be used to infer that the TTX content in flatworms is a defense mechanism. (Although, some studies show that there are high concentrations of TTX in the pharynx, or feeding organ, which has had scientists hypothesize wether or not TTX is used in prey capture.)
Very cool!!
If you’re looking for good flatworm videos, this one has a lot of interesting footage!
heyy!! So this blog is an alternate one to my main (krutomu) where I will be posting about mostly polyclad flatworms. I’m currently researching them so I will talk about some of my research on occasion as well. Feel free to send an ask if you wanna know some stuff or just wanna talk about flatworms!!
Marine Flatworms: The World of Polyclads
Marine Flatworms: The World of Polyclads Marine Flatworms provides a fascinating introduction to the intriguing world of polyclad flatworms, a group of large, free-living marine Platyhelminthes, which are found throughout the world but are most colorful in tropical waters. Although not related to molluscs, they are often mistaken for sea slugs because of their brilliant color patterns. Written in an accessible style by two leading experts in the field, this book explores flatworms’ unusual structure, feeding habits, their curious reproductive behaviour (including "penis fencing"), their mimicry and toxicology. With a foreword by Professor Reinhardt Kristensen of the Copenhagen Zoological Museum, Marine Flatworms is the first comprehensive guide to polyclad families and genera. It contains more than 300 colour photographs from every part of the world
