Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas.
Without a host to provide a blood meal, a flea's life can be as short as a few days. Under ideal conditions of temperature, food supply, and humidity, adult fleas can live for up to a year and a half. [16] Completely developed adult fleas can live for several months without eating, so long as they do not emerge from their puparia. Optimum ...
The Diplostraca or Cladocera, commonly known as water fleas, is a superorder of small, mostly freshwater crustaceans, most of which feed on microscopic chunks of organic matter, though some forms are predatory. [2] Over 1000 species have been recognised so far, with many more undescribed.
Daphnia pulex is the most common species of water flea. [3] It has a cosmopolitan distribution : the species is found throughout the Americas, Europe, and Australia. [ 4 ] It is a model species , and was the first crustacean to have its genome sequenced.
Adult snake with prominent two-toned scales giving a reticulated pattern. Australia's largest venomous snake, the king brown snake can reach 2.0 to 2.5 m (6.6 to 8.2 ft) in length with a weight of 3 to 6 kg (6.6 to 13.2 lb), [16] with males around 20% larger than females. [24]
Snakes are cold-blooded, meaning they cannot regulate their own body temperatures like humans or other warm-blooded animals. A snake’s body temperature changes with the outside temperatures.
Being able to tell the difference between, say, a fleabite, a bed bug bite, and a mosquito bite can mean the difference between an infestation (fleas, bed bugs) and figuring out whether the ...
It can also be an intermediate host for the flea tapeworm cestode Dipylidium caninum. Fleas can spread rapidly and move between areas to include eyebrows, eyelashes, and pubic regions. Hair loss as a result of itching is common, especially in wild and domestic animals. Anemia is also possible in extreme cases of high-volume infestations.
