Thelenota ananas (pineapple sea cucumber) is a species of sea cucumber characterized by its large size, warm colors, and pointed, star-shaped teats covering the entire body, grouped in rows of 2 or 3, as seen in Figure 1. Their body is reddish-orange in color, with the teats slightly darker and able to reach up to 70 centimeters (28 in) in length, with a weight of between 3 kg to 6 kg, and have numerous large tube feet on the flat ventral side of their body. T. ananas is a slow growing organism. T. ananas plays an important role in coral reef ecosystems by recycling nutrients, bioturbating sediments, buffering sea water from ocean acidification to local scales, prey to a range of predators, and acting as a host for symbiotic biota.
