Fish Have Personalities

November 22nd 2006 11:41
Lynne Sneddon of the University of Liverpool (UK) says that fish have personalities and those personalities can change in response to their experiences. She and her team observed rainbow trout in various situations in their lab, such as facing down significantly larger or smaller opponents and testing new foods.

Nothing in nature surprises me anymore. Don't know if such personality traits suggest certain forms of brain development, or what. Fascinating, to be sure.

Fish have personalities. Spiders live in family groups. Leopard seals show frustration when human divers can't "talk" to them. Animals are more and more interesting the more we learn about them. Thanks for stopping by, Deorre.

Adele,

I think birds are highly intelligent, have personalities and an extensive repertoire of language,
particularly our rainbow lorrikeets [in Australia] I am forever fascinated by watching them and communicating with them on my window sill.

They brighten my day and 'demand' my attention, but seem to know when I am busy.

I guess if one watched fish enough one would come to the same conclusions as the scientists.

That makes a lovely picture in my mind. Are the lorikeets pets or are they wild?

I keep goldfish and I do think they have different personalities. But they've been kept as pets for so long that such "adorable" traits would have been bred into them. I was a little more surprised to find that wild fish also exhibit those traits.
