Frogs are said to have two lives because they begin their lives in a completely different form than they end them.
The red blood cells of frogs are larger than human red blood cells. They are also somewhat elliptical rather than round like human red blood cells.
Frogs are another species whose farting status is uncertain. For one thing, their sphincter muscles aren’t very strong, so any gas escaping their rear end may not cause enough vibration to be audible.
Frogs may scream when they are touched because they are afraid, feel like they are in danger and want to be left alone. Screaming is a defence mechanism used by frogs to scare off predators. If you touch a frog and it screams, you should leave it alone.
Frogs and fish do not mate together and could not have viable offspring. Depending on their size, frogs and fish are each other’s predators. Frogs may grab fish in amplexus during mating season in an attempt to find a suitable female of the same species.
In sulfhemoglobin, the sulphur atom prevents the iron from binding to oxygen, and since it’s the oxygen-iron bonds that make our blood appear red, with sulfhemoglobin blood appears dark blue, green or black. Patients with sulfhemoglobinemia exhibit cyanosis, or a blueish tinge to their skin.
Brachiopods
Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus’ blood appear blue.May 24, 2018
Some types of octopus, squid, and crustaceans have blue blood. Their blood contains a high concentration of copper. When copper mixes with oxygen, it gives their blood its blue color.
The Eyes Have It
To help move the food along, frogs close their eyes and push downward with their eyelids. This presses on the food in their mouths, serving two purposes: holding the prey steady so the tongue can move it backward and pushing downward enough to help propel the food toward the throat.
Since the stercoral sac contains bacteria, which helps break down the spider’s food, it seems likely that gas is produced during this process, and therefore there is certainly the possibility that spiders do fart.
Yes, sand sharks gulp air at the surface which they release to achieve greater depth. This is the only shark species that farts.
The frog’s body is supported and protected by a bony framework called the skeleton. The skull is flat, except for an expanded area that encases the small brain. Only nine vertebrae make up the frog’s backbone, or vertebral column. … The frog has one “forearm” bone, the radio-ulna.
From high-pitched whirring, to a deep “bonk”, or an insect-like chirp, male frogs sing to attract their own kind. Female frogs even have ears tuned into the specific call of their own species, so that they can locate a male of their own species in a chorus of multiple, noisy males.
THE fact that the common frog (Rana temporaria) is capable of crying out lustily when he feels himself in danger, does not seem to have been frequently remarked. … This sound is a shrill and rather sibilant wail, like the note of a small penny trumpet or the cry of a new-born infant.
What Do Frogs Do When Scared? When frogs are scared they may jump or swim away, puff up their bodies, try to surprise their predators using color, play dead, bite, scream, urinate, camouflage, or roll away. Some frogs are poisonous and will secrete a toxic coating around their bodies to avoid being eaten.
