Clever camouflage

Certain jellyfish and larval fish, are nearly transparent, making them difficult to see in the water.

Marine animals use camouflage in various ways to blend into their surroundings, avoid predators, and ambush prey. Here are some common camouflage techniques:

1. Coloration: Many marine animals can change their color to match their environment. For example, octopuses and cuttlefish use specialized cells called chromatophores to rapidly change their skin color and pattern.
2. Countershading: This is a form of coloration where the animal's underside is lighter than its top side. This helps them blend in with the lighter surface when viewed from below and with the darker ocean depths when viewed from above. Sharks and dolphins often use this technique.
3. Mimicry: Some marine animals mimic the appearance of other objects or organisms in their environment. For example, the leafy sea dragon has appendages that resemble seaweed, making it difficult for predators to spot.
4. Disruptive Coloration: This involves patterns and markings that break up the outline of the animal, making it harder to detect. Many fish have stripes or spots that help them blend into their surroundings.
5. Transparency: Some marine animals, like certain jellyfish and larval fish, are nearly transparent, making them difficult to see in the water.
6. Texture Matching: Some animals can change the texture of their skin to match their surroundings. For example, some octopuses can alter their skin texture to resemble rocks or coral.

A seahorse can blend into its surroundings either to hide or in wait to capture prey.
