Fruit drupe attached to the receptacle. In some bramble fruits (such as blackberry) the receptacle is elongated and part of the ripe fruit, making the blackberry an "aggregate-accessory" fruit. The strawberry is also an aggregate-accessory fruit, only one in which the seeds are contained in achenes. In all these examples, the fruit develops from a single flower with numerous pistils. A multiple fruit is one formed from a cluster of flowers (called an "inflorescence"). Each flower produces a fruit, but these mature into a single mass. Examples are the pineapple, fig, mulberry, osage-orange, and breadfruit. In the photograph on the right,
Thelenota ananas over the surface of its body. It has numerous large tubed feet on its flat underside as well. This type of sea cucumber is edible and is considered a delicacy in the Far East countries. Due to intense commercial exploitation, the population of "T. ananas" has declined by 80-90% in at least 50% of its range; it is listed as endangered by IUCN. The worm pearlfish ("Encheliophis vermicularis") is a parasite of this species and each parasitised individual will host a male and female pair of the fish which live inside its body.
