🦆 Do Ducks Have Teeth?

No, ducks don’t have teeth similar to humans do. However, some of the ducks may have a bill (or beak) with sharp serrated edges. Ducks use serrated bills for catching and grasping slippery food items such as fish and vegetation. They also use them to filter water and food. These tiny bristles may look like teeth but they are not their true teeth.

🐘 Do elephants have teeth?

Yes, elephants have teeth. They have 26 teeth which include 12 deciduous premolars, 12 molars & 2 tusks as the elongated incisors. These strong premolar and molar teeth help them to chew tough vegetation. The elephant is the largest terrestrial mammal living on the Earth. They are herbivorous animals that rely on grasses, shrubs, roots, branches, tree barks & other vegetation, etc. for their survival. They have generally 26 teeth comprising 12 deciduous premolars, 12 molars & 2 tusks as the elongated incisors. Elephants are generally polyphyodont which has 4 to 6 cycles of teeth replacement throughout their lifespan. 

🕷️ How Long Can Spiders Live Without Food?

A typical spider can live for 1 to 2 months without eating food. Due to uncertainty in the food supply, spiders have evolved such that they can regulate their metabolism according to their environment. Spiders generally have a low metabolism rate compared to similar-sized ectothermic poikilotherms (50% of the expected for their size). Low metabolic rate and carnivorous diet help spiders to survive without food for a long period.

🕷️💨 Do Spiders Fart?

It is not scientifically proven yet but yes, it is possible that spiders do fart. The reasons for flatulence in spider can be ingestion of air during sucking liquid diet or the gas produced by bacteria during the breakdown of liquid food in the stercoral sac.

🕷🍴 What Eats Spiders?

Predators such as insectivorous birds, amphibians, reptiles, spider wasps, monkeys, other arachnids feed on spiders. Even some species of spiders such as wolf spiders and jumping spiders eat other spiders. Some species of male spiders are killed and eaten by their female spiders after mating. A deep-fried spider is one of the popular snacks in the town of Skuon, Cambodia.

🕷️ Are Spiders Insects?

Spiders are not insects, instead, they belong to arachnids. Spiders have two body segments, eight legs, multiple simple eyes, no antennae, and wings while insects have three body segments, six legs, one or two pairs of wings, and a pair of antennae. Therefore, spiders are not insects. Spiders are also not bugs because bugs are part of the Hemiptera order which belongs to the Insecta class. All bugs are insects and spiders are not insects. Therefore spiders are not considered bugs.

🕷️ How Long Do Spiders Live?

A typical spider can live for about 1-2 years. The lifespan of spiders depends on the species, sex, and external conditions. Female spiders usually live longer than male spiders. Some spider species such as tarantulas (15-20 years) live longer than other species such as house spiders (1-2 years). The lifespan of spiders is also gets reduced due to external factors such as parasites (Mermithid nematode), predators (hunting wasps), and many more.

🕷️ Why Do Spiders Curl Up When They Die?

Spiders control their leg movement with the help of flexor muscle (which contracts the legs inwards) and hydraulic pressure of hemolymph fluid (that helps in extending the legs). In the default position, the spider’s legs are flexed inwards due to flexor muscles. During locomotion, spiders increase their hemolymph pressure to extend their leg. When they die, this hemolymph pressure decreases, and the spider’s legs are forced to their default position. Therefore, the spider’s legs curl up in a ball when they die.

🦈How Do Fish Breathe?

Most fish can breathe underwater using their gills. In the breathing process, a large volume of water enters through the mouth and passes through the gills. These gills have comb-like feathery filaments that provide a large surface area to absorb oxygen from the water. After exchanging gases, water exits through gills openings. Note that some fish such as betta fish, and goldfish have a special breathing organ called labyrinth organ that allows them to breathe air and absorb oxygen. How fish breathe? Similar to other living organisms, fish also need oxygen for survival. We know that the fish can

🐟👂🏻 Do Fish Have Ears?

No, fish don’t have ears as humans do but they do have inner ears. Fish can hear the sound by using the auditory organ (otoliths) and the lateral line system. Some fish have enhanced hearing sense due to the presence of a swim bladder. Typically a fish has a hearing capacity in the range of 1 Hz to 1.5 kHz. Hearing is an important sense for the survival of the fish. Fish use their hearing sense to find food, habitat, and mating partner. Some fish with poor vision or living in deep dark oceans rely heavily on their auditory
