The largemouth basses homes are typically small and it generally connects with other ones. (Demers and McKinley, 1996; Sammons and Maceina, 2005) The largemouth bass mating system is polyandrous, meaning the female mates with several males during one breeding season. During the breeding season, each male makes their nest is shallow water. Nests are usually very basic in design. After the male create the nest, they do the act of courtship, and then the female swims to the nest and lay her eggs in it.
Within minutes of birth, newly born calves swim with -and in parallel to- their mothers directly behind her flipper. Although a manatee calf is probably nutritionally independent by the end of its first year, it may stay with its mother for another year or two. During this period, mother passes to her calf information on feeding and resting areas, travel routes and warm water refuges.Threats: Human-related activities represent the main threat for
Clown loaches are community fish and thrive when they have at least 4 other clown loaches to hang out with. When they are happy and well cared for they dance and frolic about (no joke). The can dance alone (jittery back and forth swim moves) while other watch or they'll dance as a group (a seemingly choreographed even where the clown loaches swim
Scientists confirm that Seahorses, Snapdragons and Pipe Fish are the only vertebrates in which the males carry the burden of pregnancy. This type of phenomenon is one that leaves more unanswered questions than answers. This pregnancy doesn’t look the same in all species. In some cases, the seahorse brood pouch (the male alternative to a uterus) stores the fertilized eggs to attach while they develop. In other cases, after the mom deposits the eggs in the brood pouch, the eggs are fully enclosed and protected from the outside world.
The article explains the phenomena of sex change in clown fish by using an unlikely event as an example, three young clownfish survive their journey into adulthood and establish a population with an unsettled anemone. Rhodes explains that two of the three fish will become male and female, while the third remains unsexual. In the event that the one female dies, the male clownfish becomes the alpha female while the unsexual third fish will become male, a process which reorganizes the gonads of the clownfish, which usually takes about two weeks. It is also mentioned that sex change does affect the behavior of the fish, with the alpha male who will eventually become female takes on the aggressive behavior of an alpha female. The author does mention that not much is known what role the brain takes in the sex change, but that it might have something to do with the excretion of hormones form the pituitary gland.
These water animals are fun to look at. It would be cool to see and watch how they swim. Some people said they move like a breakdancer. I never knew there was an animal like this in the ocean. As I read about the Spanish Dancer, I found out that there are a lot of interesting things about this neat animal.
The Port and Starboard Lightfish looks like a Pineapple. It is very exciting to observe this fish and its unique features. The Port and Starboard Lightfish is also known as the Knight fish, the Coat of Mail Fish and the Pineapple fish. It is commonly seen in harbors and reefs in the Queensland in Australia. The Port and Starboard Lightfish prefers to live in waters that are about 6 to 200 meters in depth.
Evolution was helping the tweezys out here, at any given moment evolution could have chose to kill them off and focus on a different species. Instead evolution had this bird develop a successful beak compared to other birds beaks. After the disaster the tweezys thrived then another round of natural selection and still came in seconds after the spoon mutated. Overall evolution made tweezys’ beaks different than others to see if they survived, and when they did, evolution would keep the beak type cycling around the
They have also a very big variety of shapes sizes, and colors. Sea anemones are very relatives of orals. They provide refuge for fishes and their eggs. They are known for their symbolic relation with anemone fishes and clown fishes. Anemone fishes, in return, protect the anemone from predators and they also may also remove
The ocean… The sound of the waves applauding and hugging the shore.The internal sounds of the body out in the world’s biggest swimming pool. The echo of my sister’s laughter. The salty smell so strong that one can taste it dancing on ones taste buds. The ocean looked like an enormous pool of wonder. It was exceptionally blue that day with a slight green undertone.
How is this process allowed or encouraged at SeaWorld when they are kept in a concrete pool? Each animal enclosure needs to be updated to meet the specific necessities of each animal. One risk posed by the current habitat for killer whales, is how long these animals spend at the surface in captivity. The whales can become sun burned and two killer whales have died from being bitten by a mosquito (Lewis, 2013). This is unheard of in the wild because the killer whales are able to swim away from pests such as mosquitos.
When nests are found, the biologists enter information on field cards about the number of eggs, species, whether eggs are broken, temperature of the nest and whether the eggs are polarized. If the eggs have progressed to where a shell forms, the yolk has polarized and begun developing into a baby turtle. These eggs are left in the nest, which the team monitors, patrols and tries to protect. The biologists also mark the nests from which the eggs have been removed so that other researchers from the sea turtle protection program know that the nest has already been
Intruding on the fresh water of six US states, roams the scaled head, large mouth, razor sharp teeth and protruding lower jaws of the Snakehead Fish. The life cycle of The Snakehead fish begins between June and July when females begin spawning. The female fish may lay up to 15,000 eggs one to five times per year. After 1 to 2 days, the eggs will hatch and be guarded by both parents. They feed on small crustaceans and fish larvae.
Danio rerio (also known by the common name “zebrafish” due to its conspicuous striped appearance) can be seen in the aquarium section of just about any local pet store, and it has become equally as ubiquitous in scientific research. Biologist George Streisinger is generally credited as the pioneer for D. rerio use as a model organism (Tucker). Streisinger, inspired by his home aquarium hobby, began experimenting with these diminutive fish as early as the 1970s, though his initial work gained little attention, and was at the time was not received without skepticism (Tucker). Specifically, what merit was there in studying a pet store novelty when other animals with an established history as model organisms, such as mice and fruit flies, were already widely available? At a cursory appraisal: D. rerio grows mere inches long, it is small, easily contained, and simple to care for; all are factors that make it practical for laboratory settings (Aleström et al 15).
CleanBill Dolphins try to rescue humans who are drowning. It’s as if they realize we can’t hold breathing as long as they do and push you upwards and even try to reanimate bumping you in the stomach. Although , this is believed to be done out of instinct (since we are about the same size of a baby dolphin and they have to perform this when baby dolphins are born, pretty much the same way newborn babies need a slap to start crying and breate) but I choose to believe they do it because they are awesomely intelligent and nice. 21. Revelgoodpeople The definition of the word “Sonder” – n. the realization that each random passerby is living a life as vivid and complex as your own—populated with their own ambitions, friends, routines, worries and inherited craziness—an epic story that continues invisibly around you like an anthill sprawling deep underground, with elaborate passageways to thousands of other lives that you’ll never know existed, in which you might appear only once, as an extra sipping coffee in the background, as a blur of traffic passing on the highway, as a lighted window at dusk.
