Washington University researchers have mapped the regions of the brain in mormyrid fish in extremely high detail. In a study published in the Nov. 15 issue of Current Biology, they report that the part of the brain called the cerebellum is bigger in members of this fish family compared to related fish — and this may be associated with their use of weak electric discharges to locate prey and

But research published July 13 in Proceedings of the Royal Society B finds that some individual differences in cognitive ability among fish of the same species may stem from relative size differences between specific brain regions, not just brain size overall (289:20220844, 2022). Zegni Triki, a biologist at Stockholm University, had an inkling

Helmet-heads of the freshwater fish world, African mormyrid fishes are known for having a brain-to-body size ratio that is similar to humans. But there's actually a great deal of variation in the size of mormyrid brains. These differences provide an opportunity to look at what's behind the bulk.

Figure 1. Variation in animal brain size. Across the animal kingdom, brains differ in size relative to body mass. The vertical distance between a species' data point and the regression line of its class denotes whether the species is relatively large-brained or not. The authors [3] found that after just two generations, guppies selected for

Understanding the size of a fish brain is essential in appreciating the scope of their cognitive abilities and behaviors. Despite its diminutive size, the fish brain is a marvel of evolution, tailored to fit the aquatic life perfectly. These tiny yet complex organs allow fish to navigate their environments, hunt for prey, and exhibit social

Fish with larger brains and higher intelligence have higher expression of a certain gene, Angiopoietin-1. According to a new study by researchers at the University of Helsinki, University College London (UCL) and Stockholm University when expression levels of Ang-1 are experimentally reduced, brains shrink. In the study, these trends were seen in two unrelated species of fish - guppies and

This mean intraspecific slope value (0.46) is similar to that of the encephalisation quotient reported for teleosts (0.5), which can be used to predict mean cognitive performance in fishes. Importantly, such a mean value (0.46) is much higher than in endothermic vertebrate species (≤0.3). Second, we used wild-caught adult cleaner fish

Fish literally get brainier when they have to think harder, and less brainy when they don't. At least, that is the implication of two studies by Frederic Laberge at the University of Guelph in Canada and colleagues that show fish brains grow larger relative to their body size in more challenging environments and shrink in less challenging ones.

The size of a fish's brain, for example, can vary widely depending on the species, environment, and other factors. In this article, we will explore the anatomy of fish brains, compare their size to other animals, discuss the factors that affect brain size, and examine the role of the brain in fish intelligence.

We looked at how different factors affect relative brain size across 1,176 bird species. The amount of energy parents invested in their young played a key role in the development and evolution of larger brains. Among the bird species we studied, parental provision was more important than ecological or social factors.

The best live baits for bass include worms and minnows set 1 to 3 feet below a bobber with a small weight placed 2 inches above the hook. Hooks should be larger than those used for bluegill. Largemouth have large mouths. Bass can, also, be caught using artificial lures such as jigs, crankbaits, plastic worms, etc.

The small, colorful fish is found only in central Tennessee in clear, spring-fed streams on the Barrens Plateau in Cannon, Coffee and Warren counties. The Barrens topminnow was first proposed for Endangered Species Act protection more than 40 years ago, but the species is now critically endangered due to chronic underfunding of the Act.
