Candy Crab
The candy crab (Hoplophrys oatesii) is a small, colorful species of crab known for its remarkable camouflage and vibrant appearance. These crabs are a great example of marine adaptation, blending perfectly with their coral habitat.
Appearance
- Candy crabs are tiny, typically growing to about 2 cm (0.8 inches) in length.
- They are brilliantly colored, often red, pink, yellow, or white, mimicking the coral they inhabit, especially soft corals like Dendronephthya.
- Their body is adorned with small spines and bumps that resemble the polyps of coral.
- They are masters of disguise, not just mimicking coral visually but also attaching bits of coral to their bodies for added concealment.
- This adaptation helps them avoid predators.
- As one of the smallest crabs, their diminutive size makes them hard to spot in the wild.
- Candy crabs are found in tropical coral reefs of the Indo-Pacific region, including the waters around Southeast Asia, the Philippines, and parts of the Indian Ocean.
- They reside exclusively on soft corals, especially in areas with strong currents that support coral growth.

Elegant Squat Lobster
Allogalathea elegans (known as the feather star squat lobster, crinoid squat lobster or elegant squat lobster) is a species of squat lobster that is sometimes kept in marine aquariums. Despite their common name, they are more closely related to hermit crabs than lobsters
he extremity of the body corresponds to the triangular rostrum of the animal, which are positioned on each side the pedunculated eyes. The rostrum is elongated and dorsally flattened and length varies. They have between five and nine lateral teeth.[4] The chelipeds or the first pair of legs are endowed with pincers and are longer than the animal body. The last pair of legs are wasted. The body and mainly the legs are covered with small hairs. The animal's size depends on the sex. Females are usually bigger than males but never grow over 2 cm. The animal's coloration is variable and is matching the colours of its host but not systematically. It can be uniform and varied from dark red, blackish-purple, orange or brown. But generally, the observed animals have longitudinal stripes which the thickness, the number and the tint varies.

Mantis Shrimp
They are among the most important predators in many shallow, tropical and subtropical marine habitats. However, despite being common in their habitats, they are poorly understood, as many species spend most of their lives sheltering in burrows and holes.
Mantis shrimp typically grow to around 10 cm (3.9 in) in length, while a few can reach up to 38 cm (15 in).[7] A mantis shrimp's carapace covers only the rear part of the head and the first four segments of the thorax. Mantis shrimp widely range in colour, with species mostly being shades of brown to having multiple contrasting, vivid colours.
The eyes of the mantis shrimp are mounted on mobile stalks and can move independently of each other. The extreme mobility allows them to be rotated in all three dimensions, yet the position of their eyes has shown to have no effect on the perception of their surroundings.They are thought to have the most complex eyes in the animal kingdom and have the most complex front-end for any visual system ever discovered
The mantis shrimp's second pair of thoracic appendages is adapted for powerful close-range combat. These claws can accelerate at a rate comparable to that of a .22 caliber bullet when fired, having around 1500 newtons of force with each swing/attack. The appendage differences divide mantis shrimp into two main types: those that hunt by impaling their prey with spear-like structures and those that smash prey with a powerful blow from a heavily mineralised club-like appendage. A considerable amount of damage can be inflicted after impact with these robust, hammer-like claws.

Harlequin Crab
Lissocarcinus orbicularis, common names sea cucumber crab, red-spotted white crab, and harlequin crab is a species of crab in the family Portunidae. This species gains one of its names from its close-knit relationship with holothuroids, the sea cucumbers. L. orbicularis should not be confused with L. laevis, a similar species of swimming crab, or Camposcia retusa, both of which are also commonly referred to as the harlequin crab. L. orbicularis displays numerous morphological and social adaptations for feeding and has a large distribution throughout the Indo-West Pacific.
Lives commensally on sea cucumbers and anemones, singly or in pairs. Smooth, almost round carapace with inconspicuous teeth. Basic color white with brown spots and/or stripes on the carapace, legs and claws. This pattern also occurs in reverse.

Spotted Porcelain Crab
The spotted porcelain crab (Neopetrolisthes maculatus) is a small, delicate marine crustacean known for its striking appearance and fascinating behavior. Despite their name, porcelain crabs are not true crabs but belong to the anomuran family, like hermit crabs.
Appearance
- Spotted porcelain crabs are small, reaching about 3–4 cm (1.2–1.6 inches) in width.
- Their flat, oval-shaped bodies are pale white or cream, covered with red or pink spots that give them their name.
- They have large, flattened claws (chelae) that are primarily used for defense, not feeding.
- Like all porcelain crabs, they have fragile exoskeletons that can break easily, earning them their "porcelain" moniker.
- They possess two long, feathery mouthparts called maxillipeds, used for filter-feeding.
- Found in the Indo-Pacific region, spotted porcelain crabs inhabit coral reefs, rocky substrates, and lagoons
- They have a symbiotic relationship with sea anemones, such as Heteractis and Stichodactyla species, where they live among the anemone's tentacles.

Orangutan Crab
The Orangutan Crab, also known as the Spider Crab, the Hairy Crab, the Bubble Coral Crab or the Decorator Crab comes from the family, Inachidae. These guys are only tiny, their body is only approximately 2 centimeters, but they have extra long arms to make up for this.
Appearance
- Orangutan crabs are tiny, typically measuring 1–2 cm (0.4–0.8 inches) across.
- Their bodies and legs are covered in fine, hair-like setae, which can trap algae and debris, aiding in camouflage.
- They are usually reddish, orange, or brown, though their coloration can vary depending on their environment.
- They have long, spindly legs, giving them a spider-like appearance.
- Their claws are small and delicate, used primarily for feeding rather than defense.
- Orangutan crabs are found in tropical waters of the Indo-Pacific region, particularly around coral reefs and lagoons.
- They often inhabit bubble coral (Plerogyra sinuosa) or other soft corals, where they can hide among the polyps for protection.

Hermit Crab
Hermit crabs are fascinating crustaceans that belong to the superfamily Paguroidea. Despite their name, they are not true crabs but are closely related. Known for their habit of living in empty shells for protection, hermit crabs are both intriguing and ecologically important.
Shell-Dwelling
- Hermit crabs have soft, coiled abdomens that need protection, so they inhabit discarded shells of gastropods (like snails).
- They frequently "upgrade" shells as they grow, engaging in shell-exchange behaviors.
- They have a hard exoskeleton covering the front part of their body.
- Their legs include a set of claws (chelae), with one typically larger for defense or manipulating food.
- Hermit crabs are social animals, often found in groups.
- They communicate using antennae movements, body postures, and vibrations.
- Depending on the species, they can range from a few millimeters to over a foot in length (such as the coconut crab, the largest terrestrial hermit crab).
