1.
What is the IUCN status of Seahorse?
Correct Answer
A. Near Threatened
Explanation
The IUCN status of Near Threatened indicates that the seahorse species is not currently considered to be at immediate risk of extinction, but it is close to meeting the criteria for being classified as Vulnerable. This status suggests that the seahorse population is declining or facing threats that could potentially lead to their endangerment in the near future.
2.
Who give births in seahorses?
Correct Answer
A. Male
Explanation
Seahorses are unique in that it is the male seahorse that gives birth. The female seahorse transfers her eggs to the male's pouch, where they are fertilized and develop until birth. This is a rare phenomenon in the animal kingdom, as most species have females giving birth. Seahorses have evolved this way to ensure successful reproduction and survival of their offspring.
3.
Which seahorse's scientific name is Hippocampus erectus?
Correct Answer
B. Lined Seahorse
Explanation
The scientific name for the seahorse species Hippocampus erectus is Lined Seahorse.
4.
How does seahorse sleep?
Correct Answer
B. With eyes open
Explanation
Seahorses sleep with their eyes open. This is because they do not have eyelids, so their eyes remain constantly open even when they are asleep. This allows them to stay alert and aware of their surroundings, which is important for their survival as they are vulnerable to predators. Keeping their eyes open also helps them to quickly respond to any potential threats or opportunities for food.
5.
How many predators does seahorse has?
Correct Answer
A. More than 50
Explanation
Seahorses have more than 50 predators. This means that there are over 50 different species that prey on seahorses, making them vulnerable to a wide range of threats in their natural habitat. The large number of predators highlights the challenges that seahorses face in terms of survival and the need for them to have effective camouflage and defensive strategies to avoid being eaten.
6.
Seahorses are?
Correct Answer
A. Fish
Explanation
Seahorses are classified as fish because they possess the key characteristics of fish. They have gills, fins, and scales, which are defining features of fish. Despite their unique appearance and behavior, seahorses share many anatomical and physiological traits with other fish species. They also reproduce by laying eggs, another characteristic common to fish. Therefore, seahorses belong to the category of fish.
7.
Which species of seahorse is the smallest?
Correct Answer
C. Yellow Seahorse
Explanation
The correct answer is Dwarf Seahorse. The question asks for the smallest species of seahorse, and out of the given options, the Dwarf Seahorse is known to be the smallest.
8.
How long does Sea horses usually live?
Correct Answer
A. 3-5 years
Explanation
Sea horses usually have a lifespan of 3-5 years. This is relatively short compared to other marine creatures. The main factors that contribute to their shorter lifespan include predation, habitat destruction, and vulnerability to disease. Additionally, sea horses have a unique reproductive system where the male carries and gives birth to the young, which can be physically demanding and may shorten their lifespan. Despite their short lifespan, sea horses play an important role in marine ecosystems and are fascinating creatures to study.
9.
Sea horses are unlikely to be found in
Correct Answer
A. Arctic Ocean
Explanation
Sea horses are unlikely to be found in the Arctic Ocean because they are generally found in warm and tropical waters. The Arctic Ocean is characterized by extremely cold temperatures and icy conditions, which are not suitable for sea horses to survive. Sea horses are more commonly found in the Indian Ocean, Atlantic Ocean, and Pacific Ocean, where the water temperatures are warmer and provide a more suitable habitat for these creatures.
10.
Seahorses lack?
Correct Answer
A. Stomach
Explanation
Seahorses lack a stomach. Unlike most other animals, seahorses do not have a digestive system that includes a stomach. Instead, they have a short digestive tract that allows food to pass quickly through their bodies. This unique adaptation is believed to be related to their feeding behavior, as seahorses consume small prey items that are easily digested. Without a stomach, seahorses rely on their rapid digestion to extract nutrients efficiently from their food.
