The Blue Whale is a gentle giant of the ocean, while the Mantis Shrimp is a fierce predator. These animals are very different in size, behavior, and where they live.
This article will talk about the unique traits of both the Blue Whale and the Mantis Shrimp. We will find out how different these two interesting animals really are.
There is a huge range of life in the oceans, from tiny plankton to huge whales. Mantis shrimp and blue whales are two marine marvels that stand out because they are so different from each other. One is a small crustacean that packs a powerful punch, and the other is the biggest animal that has ever been found. Let’s explore how these amazing animals differ across various factors.
Size and Appearance
The size difference between mantis shrimp and blue whales is astounding.
-
Mantis shrimp measure just 6-12 inches long as adults. They have elongated bodies encased in a hard shell-like exoskeleton. Their most distinctive feature is the pair of raptorial appendages that can deliver devastating blows.
-
In contrast, blue whales grow up to 100 feet long and can weigh over 300,000 pounds. These gentle giants have streamlined, soft-bodied forms ideally adapted for filter feeding. Their mottled blue-gray color camouflages them in the ocean depths.
Clearly mantis shrimp and blue whales represent opposite ends of the size spectrum. Yet both possess body designs allowing them to thrive in their respective niches.
Habitat
Mantis shrimp and blue whales also occupy very different ocean habitats
-
Mantis shrimp live in shallow, tropical coral reefs, rarely venturing deeper than 130 feet. They reside in burrows and crevices near shorelines.
-
Blue whales inhabit all major oceans except the Arctic. They like both the coast and the open ocean, and to find food, they dive to depths of over 1,000 feet. Their extensive migration covers thousands of miles annually.
So while mantis shrimp stay close to shore in warm waters, blue whales roam entire ocean basins from the equator to the poles. Their habitat ranges vastly surpass those of the diminutive crustaceans.
Diet and Foraging
These species likewise differ in their food sources and foraging methods.
-
As voracious predators, mantis shrimp mainly eat fish, crabs and mollusks. Using spearing or smashing appendages, they capture prey hiding in reef crevices.
-
In contrast, blue whales filter feed on tiny krill, consuming up to 4 tons daily. Lunge feeding and baleen plates let them gorge on dense krill swarms.
The shrimp are active hunters targeting hard-shelled prey, while the whales passively skim small plankton from seawater. This reflects their disparate sizes and feeding mechanics.
Defense and Aggression
Both mantis shrimp and blue whales have specialized defenses, but only the shrimp are aggressive.
-
Mantis shrimp are extraordinarily aggressive, using their hammer-like appendages to smash opponents with incredible speed and force. They even break open snail shells for food.
-
Despite their massive size, blue whales are docile creatures that flee from danger. If threatened, their only defense is their immense bulk and powerful tail. They cannot swallow anything wider than a beach ball.
So mantis shrimp can take down prey larger than themselves, while blue whales rely on passive defense to avoid predators. This likely reflects differences in their natural threats.
Senses
Mantis shrimp and blue whales have evolved unique sensory adaptations for their environments.
-
Mantis shrimp have extraordinarily complex eyes with 16 color receptors, compared to 3 in humans. This lets them see ultraviolet light and enhanced color detail.
-
Blue whales have highly sensitive hearing, using low frequencies to communicate up to 1000 miles. Their hearing evolved to detect far-off sounds in lightless ocean depths.
While mantis shrimp rely primarily on vision near the water’s surface, blue whales use sound to navigate, forage and socialize in the open seas. Their key senses align with their particular lifestyles and niches.
Conservation Status
Both species face anthropogenic threats today, but their conservation status differs significantly:
-
Mantis shrimp populations are currently stable with no major threats. Limited harvesting for aquariums occurs but is considered sustainable overall.
-
Blue whales are listed as Endangered by the IUCN Red List. Whaling devastated their numbers, and only about 10,000 survive worldwide today. Ship strikes and fishing gear entanglement are ongoing threats.
Effective management can ensure mantis shrimp remain at healthy levels. But protecting blue whales is critical for preventing their extinction after past overexploitation by whalers.
While mantis shrimp and blue whales inhabit the same oceans, they represent vastly different animals adapted to unique ecological roles. From minute shrimp to enormous endangered cetaceans, comparing these disparate creatures reveals just how biologically diverse marine environments are. Yet both play important parts in ocean food webs and ecology. Understanding their differences can help conserve these captivating animals for future generations.
Habitat And Behavior: Where Do They Live And How Do They Behave?
Mantis Shrimp are benthic creatures that live in shallow, tropical or subtropical waters. You can find them living in cracks or crevices, under rocks, or in holes they dig in the sand or mud. They are usually found along shores and are known to be solitary and territorial sea creatures. Mantis Shrimp are most commonly found in U-shaped burrows at the base of coral reefs.
Mantis Shrimp are powerful hunters and feed primarily on fish, crabs, snails, and shrimp. They use a pair of specialized mouthparts, the raptorial appendages, to catch their prey. The two kinds of Mantis Shrimp are called “spearers” and “smashers” because they catch their prey in different ways. Spearers have sharp parts that they use to spear or slice their prey. Smashers, on the other hand, have a big part that looks like a club that they use to crush their prey with their shells or hard exoskeletons.
Mantis Shrimp are not known for their communication skills. Unlike Blue Whales, they do not emit loud calls that can be heard for hundreds of miles. Instead, they produce sounds by vibrating their carapace. The low frequency rumbles of the mantis shrimp are approximately 167 Hz and last approximately 0. 2 s.
Size Comparison: Blue Whale Vs Mantis Shrimp
When it comes to size, there is a vast difference between Blue Whales and Mantis Shrimp. Blue whales are the world’s biggest animals. They can weigh up to 200 tons and be up to 100 feet long. In contrast, Mantis Shrimp are much smaller, ranging from 1 to 12 inches in size. When you put it that way, a Blue Whale can be as heavy as 33 elephants, while a Mantis Shrimp is only a few ounces.
Despite their size difference, both animals are fascinating in their own right. Blue whales are gentle giants that eat krill. Mantis shrimp, on the other hand, are aggressive hunters that use special mouth parts to catch their prey. Mantis Shrimp and Blue Whales both have different ways of catching and killing their prey. Mantis Shrimp use either sharp appendages or a large club-like appendage to catch and kill their prey.
Blue Whales talk by making loud noises that can be heard from hundreds of miles away. Mantis Shrimp make noises by shaking their shells. The Blue Whale and the Mantis Shrimp may look very different, but they are both amazing animals that need to be respected and protected.

FAQ
How are mantis shrimp different than blue whales?
Why is the mantis shrimp so special?
What are the characteristics of the mantis shrimp?
Do mantis shrimp have eyesight?
As if its predatory prowess wasn’t enough, the mantis shrimp is also endowed with incredible eyesight. Humans have three types of color-receptive cones—green, blue and red—that form the basis of how we perceive all color. The mantis shrimp has 16 types of color-receptive cones.
Can mantis shrimp see different colors?
While humans have 3 types of cells that can detect different colors and wavelengths of light, mantis shrimp have up to 16 different types of cell in their eyes. That means mantis shrimp can likely see a number of wavelengths that are far beyond human perception.
How many species of mantis shrimp are there?
About 520 species of mantis shrimp have been discovered worldwide; all living species are in the suborder Unipeltata, which arose around 250 million years ago. These aggressive and typically solitary sea creatures spend most of their time hiding in rock formations or burrowing intricate passageways in the sea bed.
Can a mantis shrimp tell the difference between a human and a butterfly?
A human could tell the difference between the colours in the left and middle columns with a 50% accuracy. A mantis shrimp could only do the same for the colours in the middle and right columns. Despite their 12 photoreceptors, mantis shrimps are worse at telling apart different colours than humans, honeybees and butterflies.
