Furthermore, some fish also have an oxytocin-enabled ability to sense another's fish's fear. Australian biologist Culum Brown has argued that fish may give the appearance of being less intelligent than they are due to differences between aquatic and terrestrial environments. [6] Fish hold records for the relative brain weights of vertebrates ...
These fish make use of spectral changes and amplitude modulation to determine factors such shape, size, distance, velocity, and conductivity. The abilities of the electric fish to communicate and identify sex, age, and hierarchy within the species are also made possible through electric fields.
Therefore, having more ruffe in the water leads to less food for other fish. This fish is unique in its ability to adapt in many habitats and temperatures, resulting in success despite such factors as climate change or other biological changes. The ruffe also has an exceptional ability to detect water vibrations through organs called neuromasts ...
The study involved experiments in which the fish species Labroides dimidiatus, called the bluestreak cleaner wrasse, was given a mirror self-recognition test, a technique developed in 1970 for ...
Cuttlefish eat small molluscs, crabs, shrimp, fish, octopuses, worms, and other cuttlefish. Their predators include dolphins, larger fish (including sharks), seals, seabirds, and other cuttlefish. The typical life expectancy of a cuttlefish is about 1–2 years. Studies are said to indicate cuttlefish to be among the most intelligent ...
Mudskippers are any of the 23 extant species of amphibious fish from the subfamily Oxudercinae of the goby family Oxudercidae. [2] They are known for their unusual body shapes, preferences for semiaquatic habitats, limited terrestrial locomotion and jumping, and the ability to survive prolonged periods of time both in and out of water.
The family Antennariidae use a unique form of locomotion which includes a jet type like propulsion that involves breathing. Water is taken in from the mouth and expelled through tube like gill openings behind the pectoral fins that propel the fish forward by performing opercular exhalations [ 14 ] The family generally has a globulous body shape ...
They are unique among electric fish in not possessing electroreceptors, meaning that they do not use an electric sense to locate prey. [2] Stargazer's paired electric organs are aligned vertically inside the head, behind the eyes. [3] Uniquely, they are used only for hunting or defence, as the fish does not electrolocate. [2]
