Fig. 2

Holothuria sanctori specimens adhered to the experimental hard substrate (tank walls) during active feeding on the soft substrate. (A–D) Sea cucumbers with their bodies partially attached to the tank wall, while the anterior section, including the mouth, extends toward and feeds on the soft substrate. Note that (A–C) are side views, whereas (D) is an upper view, showing the sea cucumber attached to the right side of the tank as it feeds on the soft substrate (100–250 μm).
