Papers, like school pad papers, have stripes printed on them as a guide for straight-lined handwriting. This is useful especially to young students learning to write legibly. You may remember that in handwriting lessons, you use the blue and red lines as boundaries of letters drawn.

A recent study of the marine hawksbill turtle's stomach contents revealed that sponges constitute a major portion of their diet.

Answer:

These structures that protect the sponges from most predators, but not turtles, are spicules.

Explanation:

Sponges skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.

There are different kinds of spicules:

- Monoaxonic spicule: needle-shaped, straights or curves

- Tetraxonic spicules: they have four prolongations

- Triaxonic or Hexaxonic spicules

- Poliaxonic spicules

Two terms can be applied to any of these spicules kinds:

- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton

- Microspicules: Variable in shape and size, with ancillary functions

Sponges have few predators thank to the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
