The blow lugworm (Arenicola marina), also known as sandworm, is a large species of marine worm.Its coiled castings are a familiar sight on a beach at low tide but the animal itself is rarely seen except by those who, from curiosity or to use as fishing bait, dig the worm out of the sand.
Sand dollars bury into intertidal sand leaving a characteristic mark at the sediment surface. This species had been recorded in Ghana though rare (Yankson and Kendall, 2001). Other species found on the West Africa shore such as sea anemone, Perna perna , Ocypode cursor, Diadema antillarum have already been described on this site.
The test of certain species of sand dollar have slits called lunules that can help the animal stay embedded in the sand to stop it from being swept away by an ocean wave. [8] In living individuals, the test is covered by a skin of velvet-textured spines which are covered with very small hairs . Coordinated movements of the spines enable sand ...
This may be detected by the physical characteristics of the sand. As the tide falls, the sand is allowed to settle; when Emerita detects this, it uses the temporary liquefaction from a breaking wave to emerge from its burrow, and is carried down the beach by the wave action. [7] Longshore drift may also drag Emerita laterally along a beach. [7]
Ghost crabs are negatively affected by human activity on sandy beaches, such as sand trampling by foot traffic, the building of seawalls, or the presence of inorganic pollutants. Due to their worldwide distribution and the ease by which their burrows can be surveyed, ghost crab burrows are regarded as valuable ecological indicators for quickly ...

The tail shaft, 2 to 3 in (5.1 to 7.6 cm) from it, is marked by a highly coiled cast of sand. The lugworm lies in this burrow with its head at the base of the head shaft, swallowing sand from time to time. This makes the columns of sand drop slightly, so there is a periodic sinking of the sand in the saucer-shaped depression.
[6] [37] Zebra mantis shrimp capture agile prey such as fish primarily at night while hidden in burrows, striking very hard and fast, with a mean peak speed 2.30 m/s (5.1 mph) and mean duration of 24.98 ms. [37] A chameleon's tongue striking ballistically at food. Chameleons (family Chamaeleonidae) are highly adapted as ambush predators. [38]
