Frogs

Leeches prefer feeding on thin-skinned animals like frogs because their skin is easier to penetrate with their mouthparts. Mammals typically have thicker skin, making it more difficult for leeches to latch on and feed. Additionally, frogs' moist environments may make them more attractive to leeches.

Some frogs are poisonous as a defense mechanism against predators. They secrete toxins through their skin or from glands that make them taste bad or even cause harm to animals that try to eat them. This adaptation helps them survive in their natural habitats without being easily preyed upon.

Tadpoles typically emerge in early spring, as the weather warms up and conditions become suitable for their development. This timing allows them to take advantage of increasing food sources and higher water temperatures for optimal growth before transitioning into froglets.

if you take a tadpole out of the water it will DIE!!!!!! do not take a tadpole out of the water until it is a frog .I'm not sure about their eggs but im pretty sure the eggs will fail to live (try Google or ask.com).

Frogs are very well-suited to their swampy and amphibious lifestyle. Their strong legs help them to swim quickly, their skin absorbs oxygen and moisture, and their long tongues catch insects from a safe distance.

Tadpoles typically hatch in the spring or early summer when water temperatures are warmer and more conducive to their development. This timing allows them to take advantage of abundant food sources and ensures that they have enough time to grow and metamorphose into frogs before winter.

Frogs have 5 tot 9 vertebrals, most frogs have 8, and 3 to 4 fused tail-bones. Frogs have 5 tot 9 vertebrals, most frogs have 8, and 3 to 4 fused tail-bones.

Frogs' eggs, or frogspawn, need water or they will dry out and die. The eggs of a frog do not have a solid, protective covering like birds' eggs or reptiles' eggs do, so laying them in water preserves the developing tadpole from dehydration.

Liquid waste is eliminated from a frog through its kidneys, which filter waste and excess substances from the blood to produce urine. Urine then travels through the ureters to the cloaca, where it is expelled from the body as waste.

Frogs are semi-aquatic animals with adaptations for both land and water. They have moist skin that helps with gas exchange and can absorb water, but they also have lungs to breathe air. They have muscular hind legs for jumping on land and webbed feet for swimming in water.

Crocodilians have a transparent nictating membrane which serves as a secondary eyelid. This inner eyelid moves from the sides while the outer eyelid moves up and down. When this transparent eye-lid is engaged, it does limit visual ability somewhat, especially in muddy, darker water. However, it protects the main eye from damage that may be caused by debris in the water (or even during scuffles with fellow crocodilians). When visual ability is limited, crocodilians have a keen sense of smell to help back them up.

The bumps on a frog are called tubercles. They are typically located on the skin of male frogs and are used during mating to grip the female frog.

Sea star eggs have more yolk compared to frog eggs. Sea star eggs are considered macrolecithal, meaning they contain a large amount of yolk which is necessary for the development of the embryos. Frog eggs, on the other hand, are typically microlecithal and contain less yolk.

Like Yin and Yang, one would have to say that males and females evolved simultaneously... and there is no male without a female.

In evolution asexual replication would have evolved before sexual replication. For example, bacteria (prokaryotes) are considered to be earlier on the evolutionary tree than eukaryotes (yeasts, molds, and all plants and animals).

The Bacteria divide asexually. However, they are also able to share genes via plasmids as well as picking up environmental DNA.

In a sense, the sharing of plasmids is similar to sexual reproduction, with the entire bacteria resembling the oocyte, and having all organelles to support life. The plasmid would resemble the spermatocyte, only having what is necessary to transmit its genes, and lacking the other cellular organelles. Note, while spermatocytes have mitocondria, for example, they do not transmit mitochondrial DNA to the oocyte.

However, the stability of the genome which would be necessary for the evolution of higher organisms would have required the development of a method not only to share genes, but to also maintain a relatively fixed genome arrangement, and thus the development of the very complex meiosis. Again, it probably would have been developed simultaneously with a mutual method for males and females to share half their DNA (except for the mitochondrial DNA that only comes from the female).

If one looks at the equine species. Different members of the equine species have different numbers of chromosomes and different distributions of genes on the chromosomes. And, while they can interbreed and produce viable first generation offspring, this creates unpaired chromosomes and the offspring are unable to undergo meiosis as would be required for producing second generation offspring.

The Homo Sapien species points back to a "Mitochondrial Eve" approximately 200,000 years ago from which all living humans derive. Neanderthal man became evolutionary distinct from Homo Sapiens around that time, but co-existed with humans for over 100,000 years more. There is no evidence of significant interbreeding of the two hominid species, perhaps because of not being able to produce viable second generation offspring just like horses and donkeys are unable to have second generation offspring.

It is likely that a chromosomal shift occurred either in a single step, or rapid succession during the time of Mitochondrial Eve that necessarily excluded interbreeding with Neanderthals. This shift would have occurred in a single tribe or family, but would have symmetrically affected both males and females of the tribe or family, with no true distinction between the males or females coming first other than an unknown firstborn in the family.

Oddly the human male lineage ("Y" Chromosome Adam) is only about 60,000 years old, and is much younger than mitochondrial Eve. Certainly "Adam" would have had ancestors with lineages tracing back to Eve's time. But, about 60,000 years ago a line of dominant males evolved which effectively was able to out compete all other homo sapien males to the point that over time it became the only surviving male bloodline.

It wouldn't be unexpected though if one considers polygamous animal species in which most females of "breeding age" eventually breed, but many males never have offspring, thus female lineages would have greater diversity than male lineages.

Frogs reproduce through a process called spawning, where female frogs release eggs and male frogs release sperm into the water simultaneously. Fertilization occurs externally, and tadpoles develop from the eggs that hatch. Reproduction typically occurs during the breeding season, which varies depending on the species and environmental conditions.

Frogs are considered environmental barometers because they are sensitive to changes in their ecosystems. Their population, behavior, and health can provide insights into the overall health of an environment. For example, declines in frog populations may indicate pollution or habitat destruction, making them valuable indicators of environmental quality.

yes...they can. I have a small frog in my backyard that I absolutely adore! Crazy I know, but he comes around at the same time every night and just kinda hangs out on the porch. I was planting some flowers around June, and when I put the shovel in the ground this little frog jumped up and it only had three limbs. I realized that I had cut it with the shovel, and felt horrible. He survived, and still comes around everynight. I have been watching him, and he has begun to grow a stump from the area that his front leg/arm was missing. It has tripled in size in the past few months, and he is beginning to use it as if he had a normal arm. I researched amphibian regeneration and found that yes, it is possible. They form a stump called a blastema on the site of detachment to form the basis for the limb, and eventually a normal, scar free limb will replace the old one and have fully restored function.

Features are a hollow nerve cord in the dorsalside of the body; ... Larger sharks have been said to exist, but at the moment have not been documented

The external organs of a frog are very complex but very easy to learn. All you have to know about the external of a frog is that it's green, slimy, and silky. The external organs are whatever your little heart desires. Thank you for reading!

There is no such thing as "tadpole eggs", as tadpoles cannot lay eggs. However, it can certainly rain frogspawn. There are many tales of creatures such as sardines, pilchards and frogs raining down over areas, so frogs' eggs, being much lighter, would easily be carried into clouds. This is caused when water from a pond is taken up into the clouds during a thunderstorm, and dumped elsewhere.

The wood frog is typically small in size, measuring about 1.5 to 3.5 inches in length. They have smooth skin with a brownish or reddish coloration and are known for the dark mask-like patch behind their eyes. Wood frogs also have a distinctive 'raccoon-like' black mask that stretches from the eye to the shoulder.

No. African dwarf frogs are not poisonous.

No, tadpoles primarily feed on algae, plants, and small insects found in their aquatic environment. Grass is not typically a part of their diet as they are adapted to consuming softer and smaller food items.

Ideally, you collect rain water. Let it set outside where it will naturally gather dust, leaves and other natural debris. After about three weeks the water will be ideally suited to begin to grow algae which is perfect for tadpoles. The ideal container is one that is relatively shallow and offers a wide surface that can be exposed to the sun. If you have an old satellite dish, wok or similar vessel the algae will grow quickly.

A frog is an amphibian that typically has smooth and moist skin, jumps to move, and lays eggs in water. In contrast, a crab is a crustacean with a hard exoskeleton, walks sideways, and typically lives in marine or freshwater habitats. Frogs typically have long hind legs for jumping, while crabs have claws for grabbing food.
